5.24.2. Command Descriptions

5.24.2.1. Configuration Commands

bgp

Syntax 
[no] bgp
Context 
config>router
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables the BGP protocol instance and BGP configuration context. BGP is administratively enabled upon creation.

The no form of this command deletes the BGP protocol instance and removes all configuration parameters for the BGP instance. BGP must be shutdown before deleting the BGP instance. An error occurs if BGP is not shutdown first.

add-paths

Syntax 
[no] add-paths
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables the context to configure multiple paths for one or more families in a BGP instance, group, or neighbor. The BGP add-path capability allows the router to send and receive multiple paths per prefix to and from a peer.

The no form of this command removes the add-path capability from the BGP instance, group, or neighbor, causing sessions established using add-paths to go down and come back up without the add-path capability.

Default 

no add-paths

ipv4

Syntax 
ipv4 send send-limit receive [none]
ipv4 send send-limit
no ipv4
Context 
config>router>bgp>add-paths
config>router>bgp>group>add-paths
config>router>bgp>group>neighbor>add-paths
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the add-path capability for IPv4 labeled routes; the add-path capability is disabled by default.

Note:

The add-path capability is not supported for IPv4 native routes (that is, IPv4 routes without a label).

The maximum number of paths to send per IPv4 NLRI is configured using the send-limit mandatory parameter. The capability to receive multiple paths per prefix from a peer is configured using the optional receive keyword. If the receive keyword is not specified, the receive capability is enabled by default.

The no form of this command disables add-path support for IPv4 routes, causing sessions established using add-paths for IPv4 to go down and come back up without the add-paths capability.

Default 

no ipv4

Parameters 
send-limit —
Specifies the maximum number of paths per IPv4 NLRI that can be advertised to add-path peers. The actual number of advertised routes may be less depending on the next-hop diversity requirement, other configuration options, route policies, and route advertisement rules.
Values—
1 to 16, none

 

Default—
max
receive —
Specifies that the router negotiates the add-paths receive capability for IPv4 routes with its peers.
none —
Specifies that the router does not negotiate the add-paths receive capability for IPv4 routes with its peers.

ipv6

Syntax 
ipv6 send send-limit receive [none]
ipv6 send send-limit
no ipv6
Context 
config>router>bgp>add-paths
config>router>bgp>group>add-paths
config>router>bgp>group>neighbor>add-paths
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the add-path capability for IPv6 labeled routes; the capability is disabled by default.

Note:

The add-path capability is not supported for IPv6 native routes (that is, IPv6 routes without a label).

The maximum number of paths to send per IPv6 NLRI is configured using the send-limit mandatory parameter. The capability to receive multiple paths per prefix from a peer is configured using the optional receive keyword. If the receive keyword is not specified, the receive capability is enabled by default.

The no form of this command disables add-path support for IPv6 routes, and causes sessions established using add-paths for IPv6 to go down and come back up without the add-path capability.

Default 

no ipv6

Parameters 
send-limit —
Specifies the maximum number of paths per IPv6 NLRI that can be advertised to add-path peers. The actual number of advertised routes may be less depending on the next-hop diversity requirement, other configuration options, route policies, and route advertisement rules.
Values—
1 to 16, none

 

Default—
max
receive —
Specifies that the router negotiates the add-paths receive capability for IPv6 routes with its peers.
none —
Specifies that the router does not negotiate the add-paths receive capability for IPv6 routes with its peers.

advertise-inactive

Syntax 
[no] advertise-inactive
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables the advertising of inactive BGP routes to other BGP peers. By default, BGP only advertises BGP routes to other BGP peers if a specific BGP route is chosen by the route table manager as the most preferred route within the system and is active in the forwarding plane. This command allows system administrators to advertise a BGP route even though it is not the most preferred route within the system for a specific destination.

The no form of this command disables the advertising of inactive BGP routers to other BGP peers.

Default 

no advertise-inactive

advertise-label

Syntax 
advertise-label ipv4 [use-svc-routes]
no advertise-label
Context 
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the IPv4 transport peers to exchange RFC 3107-labeled IPv4 routes.

If the ipv4 keyword is configured, all IPv4 routes advertised to the remote BGP peer are sent with an RFC 3107 formatted label for the destination route.

The optional keyword use-svc-routes allows the user to limit the number of BGP 3107 IPv4 labeled routes that are installed in the MPLS FIB. If the keyword is specified, only BGP 3107 labeled routes that are required by services or required for establishing a BGP session with a configured neighbor are installed in the MPLS FIB. The following will trigger installation of the MPLS label into the MPLS FIB for the received BGP 3107 IPv4 labeled route:

  1. configuration of SDP to use BGP tunnel to the far-end
  2. dynamic creation of spoke-SDP binding when a route is received through BGP AD and the far-end of the SDP binding is reachable using the labeled route
  3. installation of VPN IPv4 routes received from the PE, which is reachable using the labeled route
  4. configuration of the BGP session to a BGP peer using the bgp>neighbor CLI command, and the BGP peer is reachable using the labeled route

Other IP applications such as FTP, SSH, and other applications will not trigger installation of the IPv4 labeled routes into the MPLS FIB.

The no form of this command disables any or all configured options.

Default 

no advertise-label

Parameters 
ipv4—
Specifies the advertisement label address family for core IPv4 routes. This keyword can be specified only for an IPv4 peer.
use-svc-routes—
Optional keyword that allows the user to limit the number of BGP 3107 labeled routes that are installed in the MPLS FIB. If it is specified, only BGP 3107 labeled routes that are required by services configured in the system, or required for establishing a BGP session with a configured neighbor, are installed in the MPLS FIB.

aggregator-id-zero

Syntax 
[no] aggregator-id-zero
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command sets the router ID in the BGP aggregator path attribute to zero when BGP aggregates routes. This prevents different routers within an AS from creating aggregate routes that contain different AS paths.

When BGP is aggregating routes, it adds the aggregator path attribute to the BGP update messages. By default, BGP adds the ASN and router ID to the aggregator path attribute.

When this command is enabled, BGP adds the router ID to the aggregator path attribute. This command is used at the group level to revert to the value defined under the global level. This command is used at the neighbor level to revert to the value defined under the group level.

The no form of this command used at the global level reverts to the default, where BGP adds the ASN and router ID to the aggregator path attribute.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no aggregator-id-zero

aigp

Syntax 
[no] aigp
Context 
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables AIGP path attribute support with one or more BGP peers. BGP path selection among routes with an associated AIGP metric is based on the end-to-end IGP metrics of the different BGP paths, even when these BGP paths span more than one AS and IGP instance.

The no form of this command disables AIGP path attribute support, removes the AIGP attribute from advertised routes, and causes the AIGP attribute in received routes to be ignored.

Default 

no aigp

auth-keychain

Syntax 
auth-keychain name
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures a TCP authentication keychain to use for the session. The keychain allows the rollover of authentication keys during the lifetime of a session.

Default 

no auth-keychain

Parameters 
name
Specifies the name of the keychain, up to 32 characters, to use for the specified TCP session or sessions.

authentication-key

Syntax 
authentication-key [authentication-key | hash-key] [hash | hash2]
no authentication-key
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the BGP authentication key.

Authentication is performed between neighboring routers before setting up the BGP session by verifying the password. Authentication is performed using the MD-5 message based digest. MD5 authentication is disabled by default.

The authentication key can be any combination of ASCII characters up to 255 characters.

The no form of this command reverts to the default value.

Parameters 
authentication-key—
Specifies the authentication key. The key can be any combination of ASCII characters up to 255 characters (unencrypted). If spaces are used in the string, enclose the entire string in quotation marks (“ ”).
hash-key—
Specifies the hash key. The key can be any combination of ASCII characters up to 342 characters (encrypted). If spaces are used in the string, enclose the entire string in quotation marks (“ ”).

This is useful when a user must configure the parameter, but, for security purposes, the actual unencrypted key value is not provided.

hash—
Specifies the key is entered in an encrypted form. If the hash parameter is not used, the key is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file with the hash parameter specified.
hash2—
Specifies the key is entered in a more complex encrypted form. If the hash2 parameter is not used, the less encrypted hash form is assumed.

backup-path

Syntax 
[no] backup-path [ipv4] [ipv6]
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables BGP Fast Reroute (FRR) with Prefix-Independent Convergence (PIC), allowing for the creation of a backup path for labeled IPv4 and IPv6 BGP learned prefixes belonging to the base router. Multiple paths must be received for a prefix to take advantage of this feature.

If a prefix has a backup path and its primary paths fail, the affected traffic is rapidly diverted to the backup path without waiting for control plane reconvergence to occur. If many prefixes share the same primary paths, and in some cases also the same backup path, the time to failover traffic to the backup path is independent of the number of prefixes.

By default, IPv4 and IPv6 prefixes do not have a backup path installed in the IOM.

The no form of this command disables BGP FRR with PIC.

Default 

no backup-path

Parameters 
ipv4—
Enables BGP fast reroute for labeled IPv4 routes.
ipv6—
Enables BGP fast reroute for labeled IPv6 routes.

best-path-selection

Syntax 
best-path-selection
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables path selection configuration.

always-compare-med

Syntax 
always-compare-med {zero | infinity}
no always-compare-med strict-as {zero | infinity}
no always-compare-med
Context 
config>router>bgp>best-path-selection
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the comparison of BGP routes based on the MED attribute.

The default behavior of 7210 SAS is to compare two routes on the basis of MED only if they have the same neighbor AS (the first non-confed AS in the received AS_PATH attribute). By default, a route without a MED attribute is handled the same as though it had a MED attribute with the value 0.

The always-compare-med command without the strict-as keyword allows MED to be compared even if the paths have a different neighbor AS. In this case, if neither zero nor infinity is specified, the zero option is inferred, meaning a route without a MED is handled the same as though it had a MED attribute with the value 0. When the strict-as keyword is configured, MED is only compared between paths from the same neighbor AS, and in this case, zero or infinity is mandatory and tells BGP how to interpret paths without a MED attribute.

The no form of this command reverts to the default behavior.

Default 

no always-compare-med

Parameters 
zero—
Specifies that for routes learned without a MED attribute, a zero (0) value is used in the MED comparison. The routes with the lowest metric are the most preferred.
infinity—
Specifies that for routes learned without a MED attribute, a value of infinity (2^32-1) is used in the MED comparison. This, in effect makes, these routes the least desirable.
strict-as—
Specifies that the MEDs of two paths are compared even if they come from different neighboring AS.

as-path-ignore

Syntax 
as-path-ignore [ipv4] [vpn-ipv4]
no as-path-ignore
Context 
config>router>bgp>best-path-selection
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command determines whether the AS path is used to determine the best BGP route.

If this option is present, the AS paths of incoming routes are not used in the route selection process.

The no form of this command removes the configuration.

Default 

no as-path-ignore

Parameters 
ipv4—
Specifies that the AS-path length will be ignored for all IPv4 routes.
vpn-ipv4—
Specifies that the AS-path length will be ignored for all IPv4 VPRN routes.

ignore-nh-metric

Syntax 
ignore-nh-metric
no ignore-nh-metric
Context 
config>router>bgp>best-path-selection
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command instructs BGP to disregard the resolved distance to the BGP next-hop in its decision process for selecting the best route to a destination.

When configured in the config>router>bgp>best-path-selection context, this command applies to the comparison of two BGP routes with the same NLRI learned from base router BGP peers. When configured in the config>service>vprn context, this command applies to the comparison of two BGP-VPN routes for the same IP prefix imported into the VPRN from the base router BGP instance. When configured in the config>service>vprn>bgp>best-path-selection context, this command applies to the comparison of two BGP routes for the same IP prefix learned from VPRN BGP peers.

The no form of this command restores the default behavior where BGP factors the distance to the next-hop into its decision process.

Default 

no ignore-nh-metric

ignore-router-id

Syntax 
ignore-router-id
no ignore-router-id
Context 
config>router>bgp>best-path-selection
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command modifies the route selection behavior. When this command is enabled and the current best path to a destination was learned from eBGP peer X with BGP identifier x, new paths that are received from eBGP peer Y with BGP identifier y and are equivalent will not change the best path even if y is less than x during BGP identifier comparison.

The no form of this command restores the default behavior of selecting the route with the lowest BGP identifier (Y) as best.

Default 

no ignore-router-id

bfd-enable

Syntax 
[no] bfd-enable
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables bidirectional forwarding (BFD) to control the state of the associated protocol interface. By enabling BFD on a specific protocol interface, the state of the protocol interface is tied to the state of the BFD session between the local node and the remote node. The parameters used for the BFD are set via the BFD command under the IP interface.

IPv4 BFD can be used for multihop or single hop MP-BGP sessions. For more information about the protocols and platforms that support BFD, refer to the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Router Configuration Guide.

The no form of this command removes BFD from the associated IGP/BGP protocol adjacency.

Default 

no bfd-enable

connect-retry

Syntax 
connect-retry seconds
no connect-retry
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the BGP connect retry timer value in seconds.

When this timer expires, BGP tries to reconnect to the configured peer. This configuration parameter can be set at three levels: global level (applies to all peers), peer-group level (applies to all peers in group) or neighbor level (only applies to specified peer). The most specific value is used.

The no form of this command used at the global level reverts to the default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

connect-retry 120

Parameters 
seconds—
Specifies th BGP connect retry timer value, in seconds, expressed as a decimal integer.
Values—
1 to 65535

 

damping

Syntax 
[no] damping
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables BGP route damping for learned routes, which are defined within the route policy. Use damping to reduce the number of update messages sent between BGP peers and reduce the load on peers without affecting the route convergence time for stable routes. Damping parameters are set through route policy definition.

When damping is enabled and the route policy does not specify a damping profile, the default damping profile is used. This profile is always present and consists of the following parameters:

Half-life:

15 minutes

Max-suppress:

60 minutes

Suppress-threshold:

3000

Reuse-threshold:

750

The no form of this command used at the global level reverts route damping.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no damping

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables BGP peer tracking. BGP peer tracking allows a BGP peer to be dropped immediately if the route used to resolve the BGP peer address is removed from the IP routing table and there is no alternative available. The BGP peer will not wait for the holdtimer to expire; therefore, the BGP reconvergance process is accelerated.

The no form of this command disables peer tracking.

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command specifies the export route policy used to determine which routes are advertised to peers.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific level is used.

When multiple policy names are specified, the policies are evaluated in the order they are specified. A maximum of five (5) policy names can be configured. The first policy that matches is applied.

When multiple export commands are issued, the last command entered overrides the previous command.

When no export policies are specified, BGP routes are advertised and non-BGP routes are not advertised by default.

The no form of this command removes the policy association with the BGP instance. To remove association of all policies, use the no export command without arguments.

Default 

no export

Parameters 
policy-name—
Specifies the route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes. Route policies are configured in the config>router>policy-options context.

no hold-time
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the BGP hold time, expressed in seconds.

The BGP hold time specifies the maximum amount of time that BGP waits between successive messages (either keepalive or update) from its peer before closing the connection.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in group) or neighbor level (only applies to specified peer). The most specific value is used.

Even though the 7210 SAS implementation allows setting the keepalive time separately, the configured keepalive timer is overridden by the hold-time value under the following circumstances.

  1. If the specified hold-time is less than the configured keepalive time, the operational keepalive time is set to a third of the hold-time; the configured keepalive time is not changed.
  2. If the hold-time is set to zero, the operational value of the keepalive time is set to zero; the configured keepalive time is not changed. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

hold-time 90

Parameters 
seconds—
Specifies the hold-time, in seconds, expressed as a decimal integer. A value of 0 indicates the connection to the peer is up permanently.
Values—
0, 3 to 65535

 

strict —
When this parameter is specified, the advertised BGP hold-time from the far-end BGP peer must be greater than or equal to the specified value.

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command specifies the import route policy to be used to determine which routes are accepted from peers. Route policies are configured in the config>router>policy-options context.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific level is used.

When multiple policy names are specified, the policies are evaluated in the order they are specified. A maximum of five (5) policy names can be specified. The first policy that matches is applied.

When multiple import commands are issued, the last command entered will override the previous command.

When an import policy is not specified, BGP routes are accepted by default.

The no form of this command removes the policy association with the BGP instance. To remove association of all policies, use no import without arguments.

Default 

no import

Parameters 
policy-name—
Specifies the route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes. Route policies are configured in the config>router>policy-options context.

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the BGP keepalive timer. A keepalive message is sent every time this timer expires.

The keepalive parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

The keepalive value is generally one-third of the hold-time interval. Even though the 7210 SAS implementation allows the keepalive value and the hold-time interval to be independently set, under the following circumstances, the configured keepalive value is overridden by the hold-time value.

  1. If the specified keepalive value is greater than the configured hold-time, the specified value is ignored, and the keepalive value is set to one third of the current hold-time value.
  2. If the specified hold-time interval is less than the configured keepalive value, the keepalive value is reset to one third of the specified hold-time interval.
  3. If the hold-time interval is set to zero, the configured keepalive value is ignored. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default

local-address

Syntax 
local-address ip-address
no local-address
Context 
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the local IP address used by the group or neighbor when communicating with BGP peers.

Outgoing connections use the local-address as the source of the TCP connection when initiating connections with a peer.

When a local address is not specified, 7210 SAS uses the system IP address when communicating with IBGP peers and uses the interface address for directly connected EBGP peers. This command is used at the neighbor level to revert to the value defined under the group level.

The no form of this command removes the configured local-address for BGP.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no local-address

Parameters 
ip-address—
Specifies the local IP address.
Values—

ipv4-address:

a.b.c.d (host bits must be 0)

ipv4-prefix-length:

0 to 32

ipv6-address:

x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x: [0 to FFFF]H

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures a BGP virtual autonomous system (AS) number.

In addition to the ASN configured for BGP in the config>router>autonomous-system context, a virtual (local) ASN is configured. The virtual ASN is added to the as-path message before the router ASN makes the virtual AS the second AS in the as-path.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). Therefore, by specifying this at each neighbor level, it is possible to have a separate as-number per EBGP session.

When a command is entered multiple times for the same AS, the last command entered is used in the configuration. The private attribute can be added or removed dynamically by reissuing the command.

Changing the local AS at the global level in an active BGP instance causes the BGP instance to restart with the new local ASN. Changing the local AS at the global level in an active BGP instance causes BGP to re-establish the peer relationships with all peers in the group with the new local ASN. Changing the local AS at the neighbor level in an active BGP instance causes BGP to re-establish the peer relationship with the new local ASN.

This is an optional command and can be used in the following situation.

Example: Provider router P is moved from AS1 to AS2. The customer router that is connected to P, however, is configured to belong to AS1. To avoid reconfiguring the customer router, the local-as value on router P can be set to AS1. Therefore, router P adds AS1 to the as-path message for routes it advertises to the customer router.

The no form of this command used at the global level will remove any virtual ASN configured.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no local-as

Parameters 
as-number—
Specifies the virtual autonomous system number expressed as a decimal integer.
Values—
1 to 65535

 

private—
Specifies the local AS is hidden in paths learned from the peering.

no local-preference
Context 
config>router>bgp

config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables the context to set the BGP local-preference attribute in incoming routes if not specified and configures the default value for the attribute.

This value is used if the BGP route arrives from a BGP peer without the local-preference integer set.

The specified value can be overridden by any value set via a route policy. This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

The no form of this command at the global level specifies that incoming routes with local-preference set are not overridden and routes arriving without local-preference set are interpreted as if the route had local-preference value of 100.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no local-preference

Parameters 
local-preference—
Specifies the local preference value to be used as the override value expressed as a decimal integer.
Values—
0 to 4294967295

Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures how the BGP peer session handles loop detection in the AS path.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

Dynamic configuration changes of loop-detect are not recognized.

The no form of this command used at the global level reverts to default, which is loop-detect ignore-loop.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

loop-detect ignore-loop

Parameters 
drop-peer—
Specifies to send a notification to the remote peer and drops the session.
discard-route—
Specifies to discards routes received from a peer with the same ASN as the router. This option prevents routes looped back to the router from being added to the routing information base and consuming memory. When this option is changed, the change will not be active for an established peer until the connection is re-established for the peer.
ignore-loop—
Specifies to ignore routes with loops in the AS path but maintains peering.
off—
Disables loop detection.

Description 

This command instructs the router to negotiate the send capability in the BGP ORF negotiation with a peer.

This command also causes the router to send a community filter, prefix filter, or AS path filter configured as an inbound filter on the BGP session to its peer as an ORF Action ADD.

If the comm-id parameters are not exclusively route target communities, the router will extract appropriate route targets and use those. If, for some reason, the comm-id parameters specified contain no route targets, the router will not send an ORF.

The no form of this command causes the router to remove the send capability in the BGP ORF negotiation with a peer. The no form also causes the router to send an ORF remove action for a community filter, prefix filter, or AS path filter configured as an inbound filter on the BGP session to its peer.

Default 

no send-orf

Parameters 
comm-id—

Syntax 
[no] neighbor ip-address
Context 
config>router>bgp>group
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command creates a BGP peer/neighbor instance within the context of the BGP group.

This command can be issued repeatedly to create multiple peers and their associated configuration.

The no form of this command is used to remove the specified neighbor and the entire configuration associated with the neighbor. The neighbor must be administratively shutdown before attempting to delete it. If the neighbor is not shutdown, the command will not result in any action except a warning message on the console indicating that neighbor is still administratively up.

Parameters 
ip-address—
Specifies the IP address of the BGP peer router.
Values—

ipv4-address:

a.b.c.d (host bits must be 0)

ipv4-prefix-length:

0 to 32

ipv6-address:

x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x: [0 to FFFF]H

d: [0 to 255]D

 

peer-as

Syntax 
peer-as as-number
Context 
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the autonomous system number for the remote peer. The peer ASN must be configured for each configured peer.

For eBGP peers, the peer ASN configured must be different from the autonomous system number configured for this router under the global level since the peer will be in a different autonomous system than this router

For iBGP peers, the peer ASN must be the same as the ASN of this router configured under the global level.

This is required command for each configured peer. This may be configured under the group level for all neighbors in a particular group.

Parameters 
as-number—
Specifies the autonomous system number expressed as a decimal integer.
Values—
1 to 4294967295

 

path-mtu-discovery

Syntax 
[no] path-mtu-discovery
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables path MTU discovery for the associated TCP connections. In doing so, the MTU for the associated TCP session will be initially set to the egress interface MTU. The DF bit will also be set so that if a router along the path of the TCP connection cannot handle a packet of a particular size without fragmenting, it will send back an ICMP message to set the path MTU for the specific session to a lower value that can be forwarded without fragmenting.

The no form of this command disables path MTU discovery.

Default 

no path-mtu-discovery

preference

Syntax 
[no] preference preference
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the route preference for routes learned from the configured peers.

This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

The lower the preference the higher the chance of the route being the active route. The 7210 SAS assigns BGP routes the highest default preference compared to routes that are direct, static, or learned through MPLS or OSPF.

The no form of this command used at the global level reverts to default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

preference 170

Parameters 
preference—
Specifies the route preference expressed as a decimal integer.
Values—
1 to 255

 

purge-timer

Syntax 
[no] purge-timer minutes
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the maximum time before stale routes are purged.

Parameters 
minutes—
Specifies the duration of the purge timer, in minutes.
Values—
1 to 60

 

rapid-update

Syntax 
rapid-update [l2-vpn] [evpn]
no rapid-update
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables BGP rapid update for specified address families.

If rapid update is enabled for a set of address families, and a route belonging to a family in that set is received by the router and chosen for propagation to specific BGP peers, the remaining time on the MRAI timer of these peers is ignored and the route is transmitted immediately, along with all other pending routes for these peers, including routes of address families not specified in the rapid-update command.

The rapid-update command overrides the peer-level min-route-advertisement time and applies the minimum setting of 0 seconds to routes belonging to specified address families; routes of other address families continue to be advertised according to the session-level MRAI setting.

The no form of this command disables rapid update for all address families.

Default 

no rapid-update

Parameters 
l2-vpn—
Keyword to enable the BGP rapid update for the 12-byte Virtual Switch Instance identifier (VSI-ID) value, which consists of the 8-byte route distinguisher (RD) followed by a 4-byte value.
evpn—
Keyword to enable the BGP rapid update for the EVPN address family by including EVPN routes from the set of routes that can trigger rapid update.

rapid-withdrawal

Syntax 
[no] rapid-withdrawal
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command disables the delay (Minimum Route Advertisement) on sending BGP withdrawals. Normal route withdrawals may be delayed up to the minimum route advertisement to allow for efficient packing of BGP updates.

The no form of this command removes the configuration and reverts withdrawal processing to the normal behavior.

Default 

no rapid-withdrawal

prefix-limit

Syntax 
prefix-limit limit [log-only] [threshold percent]
no prefix-limit
Context 
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the maximum number of routes BGP can learn from a peer.

When the number of routes reaches 90% of this limit, an SNMP trap is sent. When the limit is exceeded, the BGP peering is dropped and disabled.

The no form of this command removes the configuration.

Default 

no prefix-limit

Parameters 
log-only—
Keyword to enable the warning message to be sent at the specified threshold percentage, and also when the limit is exceeded. However, the BGP peering is not dropped.
percent—
Specifies the threshold value (as a percentage) that triggers a warning message to be sent
Values—
1 to 100

 

limit—
Specifies the number of routes that can be learned from a peer expressed as a decimal integer
Values—
1 to 4294967295

 

remove-private

Syntax 
[no] remove-private {limited}
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command enables private AS numbers to be removed from the AS path before advertising them to BGP peers.

When the remove-private command is configures at the global level, it applies to all peers, regardless of group or neighbor configuration. When the parameter is set at the group level, it applies to all peers in the group, regardless of the neighbor configuration.

7210 SAS software recognizes the set of AS numbers that are defined by the Internet Assignment Numbers Authority (IANA) as private. These are AS numbers in the range 64512 through 65535, inclusive.

The no form of this command used at the global level reverts to default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no remove-private

Parameters 
limited—
Optional keyword to remove private ASNs up to the first public ASN encountered. It then stops removing private ASNs.

router-id

Syntax 
router-id ip-address
no router-id
Context 
config>router>bgp
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command specifies the router ID to be used with this BGP instance.

Changing the BGP router ID on an active BGP instance causes the BGP instance to restart with the new router ID. The router ID must be set to a valid host address.

By default, the system interface IP address is used.

Parameters 
ip-address—
Specifies the router ID, expressed in dotted-decimal notation. The allowed value is a valid routable IP address on the router, either an interface or system IP address. It is highly recommended that this address be the system IP address.
Values—
a.b.c.d

 

shutdown

Syntax 
[no] shutdown
Context 
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics.

The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.

Unlike other commands and parameters where the default state is not indicated in the configuration file, the shutdown and no shutdown states are always indicated in system generated configuration files.

Default administrative states for services and service entities are described in Special Cases.

The no form of this command places an entity in an administratively enabled state.

Special Cases 
BGP Global—
The BGP protocol is created in the no shutdown state.
BGP Group—
BGP groups are created in the no shutdown state.
BGP Neighbor—
BGP neighbors/peers are created in the no shutdown state.

type

Syntax 
[no] type {internal | external}
Context 
config>router>bgp>group
config>router>bgp>group>neighbor
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command designates the BGP peer as type internal or external.

The type internal indicates that the peer is an iBGP peer while the type external indicates that the peer is an eBGP peer.

By default, 7210 SAS derives the type of neighbor based on the local AS specified. If the local AS specified is the same as the AS of the router, the peer is considered internal. If the local AS is different, the peer is considered external.

The no form of this command used at the group level reverts to the default value.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default 

no type

Parameters 
internal—
Keyword to configure the peer as internal.
external—
Keyword to configure the peer as external.

5.24.2.2. Other BGP-Related Commands

autonomous-system

Syntax 
autonomous-system autonomous-system
no autonomous-system
Context 
config>router
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the AS number for the router. A router can only belong to one AS. An ASN is a globally unique number with an AS. This number is used to exchange exterior routing information with neighboring ASs and as an identifier of the AS.

If the ASN is changed on a router with an active BGP instance, the new ASN is not used until the BGP instance is restarted either by administratively disabling or enabling (shutdown/no shutdown) the BGP instance or rebooting the system with the new configuration.

Parameters 
as-number—
Specifies the ASN, expressed as a decimal integer.
Values—
1 to 4294967295

 

router-id

Syntax 
router-id ip-address
no router-id
Context 
config>router
Supported Platforms 

Supported on all 7210 SAS platforms as described in this document

Description 

This command configures the router ID for the router instance.

The router ID is used by both OSPF and BGP routing protocols in this instance of the routing table manager.

When a new router ID is configured, protocols are not automatically restarted with the new router ID. The next time a protocol is initialized, the new router ID is used. This can result in an interim period of time when different protocols use different router IDs.

To force the new router ID to be used, issue the shutdown and no shutdown commands for each protocol that uses the router ID, or restart the entire router.

By default, the system uses the system interface address (which is also the loopback address).

If a system interface address is not configured, use the last 32 bits of the chassis MAC address.

The no form of this command reverts to the default value.

Parameters 
ip-address—
Specifies the router ID, expressed in dotted-decimal notation. The allowed value is a valid routable IP address on the router, either an interface or system IP address. It is highly recommended that this address be the system IP address.
Values—
a.b.c.d

Description 

This command displays BGP routes that have been dampened due to route flapping. This command can be entered with or without a route parameter. If no parameters are included, all dampened routes are listed.

When the keyword detail is included, more detailed information is displayed.

If a damp-type is specified, only those types of dampened routes (decayed, history, or suppressed) are displayed. Routes that have a state of decayed have gained penalties for flapping but have not yet reached the suppression limit. Routes that have a state of history have had a route flap and have been withdrawn. Routes that have a state of suppressed have reached the suppression limit and are not considered in BGP path selection.

Parameters

Description 

This command displays BGP neighbor information. This command can be entered with or without any parameters.

When this command is issued without any parameters, information about all BGP peers displays.

When the command is issued with a specific IP address or ASN, information regarding only that specific peer or peers with the same AS displays.

When either received-routes or advertised-routes is specified, the routes received from or sent to the specified peer are listed (see Sample Output for BGP Neighbor Received Routes). This information is not available with SNMP.

When either history or suppressed is specified, the routes learned from those peers that either have a history or are suppressed are listed.

The State field displays the BGP peer protocol state. In addition to the standard protocol states, this field can also display the Disabled operational state, which indicates that the peer is operationally disabled and must be restarted by the operator.

Parameters 
ip-address—
Displays information for the specified IP address.
Values—

ipv4-address:

a.b.c.d (host bits must be 0)

ipv6-address:

x:x:x:x:x:x:x:x[-interface]

x:x:x:x:x:x:d.d.d.d[-interface]

x:

[0 to FFFF]H

d:

[0 to 255]D

interface: 32 characters maximum, mandatory for link local

addresses.

 

as-number—
Displays information for the specified ASN.
Values—
1 to 65535

 

family—
Specifies the type of routing information to be distributed by this peer group.
Values—
ipv4 — Displays only those BGP peers that have the IPv4 family enabled.
vpn-ipv4 — Displays only those BGP peers that have the VPN-IPv4 family enabled.
ipv6 — Displays only those BGP peers that have the IPv6 family enabled.
vpn-ipv6 — Displays only those BGP peers that have the VPN-IPv4 family enabled.

 

filter1—
Displays information for the specified IP address
Values—
received-routes — Displays the number of routes received from this peer.
advertised-routes — Displays the number of routes advertised by this peer.
history — Displays statistics for dampened routes.
suppressed — Displays the number of paths from this peer that have been suppressed by damping.
detail — Displays detailed information pertaining to filter1.

 

filter2—
Displays information for the specified ASN.
Values—
history — Display statistics for dampened routes.
suppressed — Display the number of paths from this peer that have been suppressed by damping.
detail — Displays detailed information pertaining to filter2.

 

brief—
Displays information in a brief format. This parameter is only supported with received-routes and advertised-routes.
orf—
Displays outbound route filtering for the BGP instance. ORF (Outbound Route Filtering) is used to inform a neighbor of targets (using target-list) that it is willing to receive. This mechanism helps lessen the update exchanges between neighbors and saves CPU cycles to process routes that could have been received from the neighbor only to be dropped/ignored.
filter3—
Displays path information for the specified IP address.
Values—
send — Displays the number of paths sent to this peer.
receive — Displays the number of paths received from this peer.

 

graceful-restart —
Displays neighbors configured for graceful restart.
