Topics in this section include:

  1. IP Multicast Configuration Overview
  2. Basic IP Multicast Configuration
  3. Common Configuration Tasks
  4. Service Management Tasks

3.12. IP Multicast Configuration Overview

Nokia 7705 SAR routers use IGMP and MLD to manage membership of host receivers for a given multicast session. The routers use PIM-SSM or PIM-SM to connect to the multicast source and to the network.

Traffic can only flow away from the router to an IGMP or MLD interface; it can flow both to and from a PIM interface. A router directly connected to a source of multicast traffic must have PIM enabled on the interface to that source. The traffic travels through a network from PIM interface to PIM interface, and arrives on an IGMP- or MLD-enabled interface.

3.12.1. IGMP and MLD

The IGMP and MLD CLI contexts are created when the config>router>igmp and config>router>mld commands are run. They are not operational until at least one interface is specified in the context, at which time the interface is enabled for IGMP or MLD and is called an IGMP or MLD interface. When enabled, the interface can be configured with IGMP or MLD parameters, which are in addition to the standard parameters for the interface when it is created.

You can filter traffic on an IGMP or MLD interface by defining and importing a routing policy. You can also define the maximum number of groups to which the interface can belong.

Note:

Before an IP interface can be specified in an IGMP or MLD context, it must be created on the 7705 SAR (config>router>interface or config>service>ies>interface).

3.12.1.1. Static Groups

Static IGMP and MLD group memberships can be configured so that multicast forwarding can be set up without any host receivers in the group. When static IGMP or MLD group membership is enabled, data is forwarded to an interface even though membership reports from one or more host members have not been received.

When static IGMP or MLD group entries on point-to-point links that connect routers to a rendezvous point (RP) are configured, the static IGMP or MLD group entries do not generate join messages toward the RP. When a host wants to receive multicast sessions, it sends a join message to each multicast group it wants to join. When a host wants to leave a multicast session, it sends a Leave message to each multicast group it wants to leave.

A multicast router keeps a list of multicast group memberships for each attached network and an interval timer for each membership. Host receivers issue a Multicast Group Membership Report when they want to receive a multicast session. In MLDv2, Leaves and Joins are both sub-messages of Report messages. These reports are sent to all multicast routers.

3.12.1.2. SSM Translation

The 7705 SAR supports SSM translation at both the protocol level and the interface level for both IGMP and MLD. When configured at the protocol level, the specified group and source addresses apply to all newly created IGMP and MLD interfaces. Configuring ssm-translation at the interface level overrides any protocol-level values for the specified interface.

3.12.2. PIM

Use the config>router>pim command to enable the PIM CLI context. The PIM protocol is not operational until at least one interface is specified for it, at which time the interface is enabled for PIM and is called a PIM interface. Once enabled, a PIM interface can be configured with PIM parameters, which are in addition to the standard parameters for the interface when it is created. When PIM is operational, data is forwarded to network segments with active host receivers that have explicitly requested the multicast group.

Note:

  1. Before an IP interface can be specified in the PIM context, it must be created on the 7705 SAR (config>router>interface or config>service>ies>interface).
  2. PIM interfaces can be automatically created once an IP or IES interface has been created by using the apply-to command.

3.12.3. Hardware Support

  1. all Ethernet adapter cards
  2. 6-port SAR-M Ethernet module
  3. 2-port 10GigE (Ethernet) module

  6. all OC3/STM1 adapter cards
  7. the 4-port DS3/E3 Adapter card
  8. all datapath Ethernet ports on all fixed 7705 SAR platforms

3.13. Basic IP Multicast Configuration

Perform the following basic multicast configuration tasks:

Note:

Interfaces are created using the config>router>interface or config>service>ies>interface command (IES only), and then enabled and configured for IGMP, MLD, or PIM using the config>router>igmp>interface or mld>interface or pim>interface command.

For IGMP:

  1. enable IGMP (required)
  2. configure IGMP interfaces (required)
  3. specify IGMP version on the interface (optional)
  4. configure static (S,G) or (*,G) (optional)
  5. configure SSM translation (optional)

For MLD:

  1. enable MLD (required)
  2. configure MLD interfaces (required)
  3. specify MLD version on the interface (optional)
  4. configure static (S,G) or (*,G) (optional)
  5. configure SSM translation (optional for (S,G), required for (*,G))

For PIM:

  1. enable PIM (required)
  2. add interfaces so the protocol establishes adjacencies with the neighboring routers (required)
  3. configure a group-to-RP mapping (required) by either:
    1. configuring static group-to-RP mapping
    2. enabling candidate RP or bootstrap mechanism on some routers
  4. enable unicast routing protocols to learn routes towards the RP (for (*,G)) and source (for (S,G)) for reverse path forwarding (required)
  5. add SSM ranges (optional)
  6. enable candidate BSR (optional)
  7. enable candidate RP (optional)
  8. change hello interval (optional)
  9. configure route policies (bootstrap-export, bootstrap-import, and import join and register) (optional)

3.14. Common Configuration Tasks

The following sections show the CLI syntax and examples for:

  1. Configuring IGMP and MLD Parameters
  2. Configuring PIM Parameters

3.14.1. Configuring IGMP and MLD Parameters

This section contains the following subsections:

  1. Enabling IGMP or MLD
  2. Configuring IGMP and MLD
  3. Configuring IGMP and MLD Interfaces
  4. Configuring IGMP and MLD Interface Static Multicast
  5. Configuring IGMP and MLD SSM Translation

3.14.1.1. Enabling IGMP or MLD

Use the following CLI syntax to enable IGMP or MLD.

CLI Syntax:
config>router# igmp
CLI Syntax:
config>router# mld

The following displays an enabled IGMP example. An MLD display would look similar.

*A:7705custDoc:Sar18>config>router# info detail
...
#------------------------------------------
echo "IGMP Configuration"
#------------------------------------------

          robust-count 2
          no shutdown
     exit
#------------------------------------------
*A:7705custDoc:Sar18>config>system#

3.14.1.2. Configuring IGMP and MLD

Use the following CLI syntax to configure IGMP and MLD:

CLI Syntax:
config>router# igmp
query-interval seconds
query-last-member-interval seconds
query-response-interval seconds
robust-count robust-count
[no] shutdown
CLI Syntax:
config>router# mld
query-interval seconds
query-last-member-interval seconds
query-response-interval seconds
robust-count robust-count
[no] shutdown

The following displays an IGMP configuration example. An MLD example would look similar.

Example:
config>router# igmp
config>router>igmp# query-interval 150
config>router>igmp>if# query-last-member-interval 3
config>router>igmp>if# query-response-interval 15
config>router>igmp>if# robust count 3
config>router>igmp>if# exit
*A:7705custDoc:Sar18>config>router>igmp# info detail
----------------------------------------------
        query-interval 150
        query-last-member-interval 3
        query-response-interval 15
        robust-count 3
        no shutdown
----------------------------------------------
*A:7705custDoc:Sar18>config>router>igmp#

3.14.1.3. Configuring IGMP and MLD Interfaces

IGMP and MLD are supported on both access and network interfaces.

Note:

MLD “query” parameters can be configured at both the MLD protocol and interface levels. When configured at the protocol level, settings apply to all new interfaces added to the context. Configuring the “query” parameters at the interface level overrides the protocol-level configuration for the specified interface.

See Configuring IGMP and MLD for an example of query parameter configuration.

Use the following CLI syntax to configure an IGMP or MLD interface:

CLI Syntax:
config>router# igmp
interface ip-int-name
[no] disable-router-alert-check
[no] import policy-name
[no] max-groups value
[no] max-grp-sources value
[no] subnet-check
[no] version version
[no] shutdown
CLI Syntax:
config>router# mld
interface ip-int-name
[no] disable-router-alert-check
[no] import policy-name
[no] max-groups value
[no] query-interval seconds
[no] query-last-member-interval seconds
[no] query-response-interval seconds
[no] version version
[no] shutdown

The following example displays IGMP interface configuration command usage. An MLD interface example would look similar.

Example:
config>router#
config>router>igmp# interface "igmp_interface"
config>router>igmp>if# max-groups 3
config>router>igmp>if# max-grp-sources 2
config>router>igmp>if# import igmp_policy1
config>router>igmp>if# exit

The following example displays the IGMP interface configuration:

*A:7705custDoc:Sar18>config>router>igmp>interface# info detail
----------------------------------------------
        interface "igmp_interface"
            import igmp_policy1
            version 3
            subnet-check
            max-groups 3
            max-grp-sources 2
            no disable-router-alert-check
            no shutdown
        exit
----------------------------------------------
*A:7705custDoc:Sar18>config>router>igmp#

3.14.1.4. Configuring IGMP and MLD Interface Static Multicast

The maximum number of static groups and sources that can be configured on a group interface is controlled by the max-groups and max-grp-sources commands. A static (*,G) cannot be added to a group if an (S,G) exists. Similarly, a static (S,G) cannot be added to a group if a (*,G) exists.

A static group is not created until a source has been specified.

Use the following syntax to configure an IGMP or MLD static multicast group and source for a multicast interface:

CLI Syntax:
config>router# igmp
interface ip-int-name
static
group grp-ip-address
source ip-address
starg
CLI Syntax:
config>router# mld
interface ip-int-name
static
group grp-ipv6-address
source ipv6-address
starg

The following example displays an IGMP interface configuration for static multicast. An MLD interface example would look similar except that it would use IPv6 group and source addresses.

Example:
config>router>igmp# interface igmp_interface
config>router>igmp>if# static
config>router>igmp>if>static# group 239.255.1.3
config>router>igmp>if>static>group# source 10.0.2.8
config>router>igmp>if>static>group# source 10.0.2.9
config>router>igmp>if>static# group 239.255.0.3
config>router>igmp>if>static>group# exit
config>router>igmp>if>static>group# source 10.0.184.197
config>router>igmp>if>static>group# source 10.0.184.198
config>router>igmp>if>static>group# exit
config>router>igmp>if>static# exit
config>router>igmp>if# exit

The following example displays the configuration for IGMP. An MLD example would look similar except that it would use IPv6 group and source addresses.

A:7705custDoc:Sar18>config>router>igmp# info
----------------------------------------------
     interface "igmp_interface"
          static
               group 239.255.1.3
                    source 10.0.2.8
                    source 10.0.2.9
               exit
               group 239.255.0.3
                    source 10.0.184.197
                    source 10.0.184.198
               exit
          exit
     exit
----------------------------------------------
A:7705custDoc:Sar18>config>router>igmp#

3.14.1.5. Configuring IGMP and MLD SSM Translation

SSM translation can be configured for IGMP and MLD at the protocol and the interface levels. When configured at the protocol level, settings apply to all new interfaces added to the context. Configuring SSM translation at the interface level overrides the protocol-level configuration for the specified interface.

The group range is not created until a source has been specified.

Use the following syntax to configure IGMP and MLD SSM translation parameters at the protocol and interface levels:

CLI Syntax:
config>router# igmp
ssm-translate
grp-range start end
source ip-address
CLI Syntax:
config>router# igmp
interface ip-int-name
ssm-translate
grp-range start end
source ip-address
CLI Syntax:
config>router# mld
ssm-translate
grp-range start end
source ipv6-address
CLI Syntax:
config>router# mld
interface ip-int-name
ssm-translate
grp-range start end
source ipv6-address

The following example displays the command usage to configure IGMP SSM translation at the protocol and interface levels. Examples for MLD protocol and MLD interfaces would look similar. MLD would use IPv6 group and source addresses.

Example:
config>router# igmp
config>router>igmp# ssm-translate
config>router>igmp>ssm# grp-range 192.0.2.0 192.0.2.10
config>router>igmp>ssm>grp-range# source 10.10.10.100
config>router>igmp>ssm>grp-range# exit
config>router>igmp# interface igmp_if
config>router>igmp>interface>ssm# grp-range 192.0.2.20 192.0.2.30
config>router>igmp>interface>ssm>grp-range# source 10.10.10.110
config>router>igmp>interface>ssm>grp-range# source 10.10.10.111

The following example displays the SSM translation configuration at the IGMP protocol and interface levels:

A:7705custDoc:Sar18>config>router>igmp# info
----------------------------------------------
     ssm-translate
          grp-range 192.0.2.0 192.0.2.10 
               source 10.10.10.100 
          exit
     interface "igmp_if"
         max-groups 2
         max-grp-sources 3
         ssm-translate
             grp-range 192.0.2.20 192.0.2.30
                 source 10.10.10.110
                 source 10.10.10.111
         exit
----------------------------------------------

3.14.2. Configuring PIM Parameters

This section contains the following subsections:

  1. Enabling PIM
  2. Configuring PIM Interface Parameters
  3. Configuring a Rendezvous Point (RP)
  4. Importing PIM Join or Register Policies
  5. Configuring Multicast Source Discovery Protocol (MSDP) Parameters

3.14.2.1. Enabling PIM

When configuring PIM, make sure to enable PIM on all interfaces for the routing instance; otherwise, multicast routing errors can occur.

Use the following CLI syntax to enable PIM.

CLI Syntax:
config>router# pim

The following example displays the detailed output when PIM is enabled without a PIM interface configured. See Configuring PIM Interface Parameters for the additional configuration settings when a PIM interface is configured.

3.14.2.2. Configuring PIM Interface Parameters

To create a PIM interface, first create an IP interface using the config>router> interface or the config>service>ies>interface command (IES only). Then use the config>router>pim>interface command to configure PIM interface parameters.

The following example displays the command usage to configure PIM interface parameters:

Example:
config>router# pim
config>router>pim# interface "pim_interface"
config>router>pim>if# assert-period assert-period
config>router>pim>if# [no] bfd-enable [ipv4 | ipv6]
config>router>pim>if# [no] bsm-check-rtr-alert
config>router>pim>if# hello-interval hello-interval
config>router>pim>if# hello-multiplier deci-units
config>router>pim>if# instant-prune-echo
config>router>pim>if# [no] ipv4-multicast-disable
config>router>pim>if# [no] ipv6-multicast-disable
config>router>pim>if# max-groups value
config>router>pim>if# multicast-senders auto
config>router>pim>if# priority dr-priority
config>router>pim>if# [no] shutdown
config>router>pim>if# sticky-dr [priority dr-priority]
config>router>pim>if# [no] three-way-hello
config>router>pim>if# [no] tracking-support
config>router>pim>if# exit

The following example displays the detailed PIM interface configuration:

*A:7705custDoc:Sar18>config>router>pim# info detail

3.14.2.3. Configuring a Rendezvous Point (RP)

When configuring a Rendezvous Point (RP), you can configure parameters for an RP candidate, a BSR candidate, or a static RP.

The following example displays the command usage to configure an RP:

Example:
config>router# pim
config>router>pim# rp
config>router>pim>rp# anycast rp-ip-address
config>router>pim>rp>anycast# rp-set-peer ip-address
config>router>pim>rp# auto-rp-discovery
config>router>pim>rp# bootstrap-export policy-name
config>router>pim>rp# bootstrap-import policy-name
config>router>pim>rp# bsr-candidate
config>router>pim>rp>bsr-candidate# address ip-address
config>router>pim>rp# rp-candidate
config>router>pim>rp>rp-candidate# address ip-address
config>router>pim>rp>rp-candidate# group-range {grp-ip-address/mask | grp-ip-address netmask}
config>router>pim>rp# static
config>router>pim>rp>static# address ip-address
config>router>pim>rp>static# group-prefix {grp-ip-address/mask | grp-ip-address netmask}
config>router>pim>rp>static# override

The following example displays the detailed RP configuration:

*A:7705custDoc:Sar18 Dut-B>config>router>pim>rp# info detail
----------------------------------------------
                    no bootstrap-import
                    no bootstrap-export

                    exit

3.14.2.4. Importing PIM Join or Register Policies

The import command provides a mechanism to control the (*,G) or (S,G) state that gets created on a router. Import policies are defined in the config>router>policy-options context.

Up to five join policies can be included in a single join-policy command and up to five register policies can be included in a single register-policy command. Each use of the join-policy or register-policy command overrides the previous use and resets the list of import policies.

Note:

In the import policy, if a policy action is not specified in the entry, the default-action takes precedence. Similarly, if there are no entry matches, the default-action takes precedence. If no default-action is specified, the default default-action is executed.

Use the following commands to import PIM join policies:

CLI Syntax:
config>router# pim
import {join-policy | register-policy} [policy-name [...up to 5 max]]

The following example displays the commands used to import a join policy statement named “pim_join”. The example also displays the commands used to import three register policies. For information on configuring a join or register policy, see the “Configuring PIM Join or Register Policies” section in the 7705 SAR Router Configuration Guide.

Example:
config>router# pim
config>router>pim# import join-policy “pim_join”
config>router>pim# import register-policy “register_join” “register_join2” “register_join3”
config>router>pim# no shutdown

The following example displays the PIM configuration:

A:7705custDoc:Sar18>config>router>pim# info
----------------------------------------------
...
     import join-policy "pim_join"
     import register-policy "register_join" "register_join2" "register_join3"
     interface "pim_interface"
     exit
...
----------------------------------------------
A:7705custDoc:Sar18>config>router>pim#

3.14.2.5. Configuring Multicast Source Discovery Protocol (MSDP) Parameters

Use the following CLI syntax to configure MSDP parameters:

CLI Syntax:
config>router# msdp
peer peer-address
active-source-limit number
authentication-key [authentication-key|hash-key]
[hash|hash2]
default-peer
export policy-name [policy-name...(up to 5 max)]
import policy-name [policy-name...(up to 5 max)]
local-address address
receive-msdp-msg-rate number interval seconds [threshold number]
no shutdown
no shutdown

The following example displays the command usage to configure basic MSDP parameters.

Example:
config>router>msdp# peer 10.20.1.1
config>router>msdp>peer# local-address 10.20.1.6
config>router>msdp>peer# no shutdown
config>router>msdp>peer# exit
config>router>msdp# no shutdown
config>router>msdp#

The following example displays the basic MSDP for configuration.

ALA-48>config>router>msdp# info
-------------------------------------------
        peer 10.20.1.1
            local-address 10.20.1.6
        exit
-------------------------------------------
ALA-48>config>router>msdp#

3.15. Service Management Tasks

This section discusses the following multicast configuration management tasks:

  1. Disabling IGMP, MLD, PIM, and MSDP

3.15.1. Disabling IGMP, MLD, PIM, and MSDP

To disable IP multicast, disable PIM and disable IGMP or MLD (or both).

Use the following CLI syntax to disable IGMP, MLD, PIM, and MSDP:

CLI Syntax:
config>router#
igmp
shutdown
mld
shutdown
pim
shutdown
msdp
shutdown

The following example displays the command usage to disable multicast:

Example:
config>router# igmp
config>router>igmp# shutdown
config>router>igmp# exit
config>router# mld
config>router>mld# shutdown
config>router>mld# exit
config>router# pim
config>router>pim# shutdown
config>router>pim# exit
config>router# msdp
config>router>msdp# shutdown
config>router>msdp# exit

The following example displays the configuration outputs:
