Session parameters commands

session-parameters

Syntax

session-parameters

Context

config>router>ldp

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

Commands in this context configure peer-specific parameters.

peer

Syntax

[no] peer ip-address

Context

config>router>ldp>session-parameters

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures parameters for an LDP peer.

Parameters

ip-address

Specifies the IP address of the LDP peer, in dotted-decimal notation.

export-addresses

Syntax

export-addresses policy-name [policy-name ... (up to 5 max)]

no export-addresses

Context

config>router>ldp>session-params>peer

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the export prefix policy to local addresses advertised to this peer.

Policies are configured in the config>router>policy-options context. A maximum of five policy names can be specified. The specified names must already be defined.

The no form of this command removes the policy from the configuration.

Default

no export-addresses

Parameters

policy-name

Specifies the export-prefix route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters excluding double quotes. If the string contains spaces, use double quotes to delimit the start and end of the string.

export-prefixes

Syntax

export-prefixes policy-name [policy-name ... (up to 5 max)]

no export-prefixes

Context

config>router>ldp>session-params>peer

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the export route policy used to determine which prefixes received from other LDP and T-LDP peers are redistributed to this LDP peer via the LDP/T-LDP session to this peer. A prefix that is filtered out (deny) is not exported. A prefix that is filtered in (accept) is exported.

If no export policy is specified, all FEC prefixes learned are exported to this LDP peer. This policy is applied in addition to the global LDP policy and targeted session policy.

Policies are configured in the config>router>policy-options context. A maximum of five policy names can be specified. The peer address must be the peer LSR ID address. The specified names must already be defined.

The no form of this command removes the policy from the configuration.

Default

no export-prefixes

Parameters

policy-name

Specifies the export-prefix route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters excluding double quotes. If the string contains spaces, use double quotes to delimit the start and end of the string.

fec-type-capability

Syntax

fec-type-capability

Context

config>router>ldp>session-params>peer

config>router>ldp>interface-params>interface>ipv4

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

Commands in this context configure FEC type capabilities for the session or interface.

prefix-ipv4

Syntax

prefix-ipv4 {enable | disable}

Context

config>router>ldp>session-params>peer>fec-type-capability

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command enables or disables IPv4 prefix FEC capability on the session or interface.

Default

prefix-ipv4 enable

Parameters

enable

Keyword to specify that IPv4 prefix FEC capability is enabled.

disable

Keyword to specify that IPv4 prefix FEC capability is disabled.

fec129-cisco-interop

Syntax

[no] fec129-cisco-interop

Context

config>router>ldp>session-params>peer

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures whether LDP provides translation between non-compliant FEC 129 Cisco formats. Peer LDP sessions must be manually configured toward the non-compliant Cisco PEs.

When enabled, Cisco non-compliant format is used to send and interpret received label release messages. The FEC129 SAII and TAII fields are reversed.

The no form of this command disables use and support of Cisco non-compliant forms. The peer address must be the peer LSR ID address.

Default

no fec129-cisco-interop

import-prefixes

Syntax

import-prefixes policy-name [policy-name... (up to 5 max)]

no import-prefixes

Context

config>router>ldp>session-params>peer

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the import FEC prefix policy to determine which prefixes received from this LDP peer are imported and installed by LDP on this node. If resolved, these FEC prefixes are then redistributed to other LDP and T-LDP peers. A FEC prefix that is filtered out (deny) is not imported. A FEC prefix that is filtered in (accept) is imported.

If no import policy is specified, the node imports all prefixes received from this LDP/T-LDP peer. This policy is applied in addition to the global LDP policy and targeted session policy. Policies are configured in the config>router>policy-options context. A maximum of five policy names can be specified. The peer address has to be the peer LSR ID address. The specified names must already be defined.

The no form of this command removes the policy from the configuration.

Default

no import-prefixes

Parameters

policy-name

Specifies the import-prefix route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters excluding double quotes. If the string contains spaces, use double quotes to delimit the start and end of the string.
