Multicast Configuration Overview
The routers use IGMP to manage membership for a given multicast session. IGMP is not enabled by default. When enabled, at least one interface must be specified in the IGMP context as IGMP is an interface function. Creating an interface enables IGMP. Traffic can only flow away from the router to an IGMP interface and to and from a PIM interface. A router directly connected to a source must have PIM enabled on the interface to that source. The traffic travels in a network from PIM interface to PIM interface and arrives finally on an IGMP enabled interface.
The IGMP CLI context allows you to specify an existing IP interface and modify the interface-specific parameters. Static IGMP group memberships can be configured to test multicast forwarding without a receiver host. When IGMP static group membership is enabled, data is forwarded to an interface without receiving membership reports from host members.
When static IGMP group entries on point-to-point links that connect routers to a rendezvous point (RP) are configured, the static IGMP group entries do not generate join messages toward the RP. When a host wants to receive multicast sessions it sends a join message for each multicast group it wants to join. Then, a leave message may be sent for each multicast group it no longer wishes to participate with.
A multicast router keeps a list of multicast group memberships for each attached network, and an interval timer for each membership. Hosts issue a Multicast Group Membership Report when they want to receive a multicast session. The reports are sent to all multicast routers.
PIM is not enabled by default. When PIM is enabled, data is forwarded to network segments with active receivers that have explicitly requested the multicast group. When enabled, at least one interface must be specified in the PIM context as PIM is an interface function. Creating an interface enables PIM.

Importing PIM Join/Register Policies
The import command provides a mechanism to control the (*,G) and (S,G) state that gets created on a router. Import policies are defined in the config>router>policy-options context.
Note, in the import policy, if an action is not specified in the entry then the default-action takes precedence. If no entry matches then the default-action also takes precedence. If no default-action is specified, then the default default-action is executed.
Use the following commands to configure PIM parameters:
CLI Syntax: config>router# pim
import {join-policy|register-policy} [policy-name
[.. policy-name]
 
The following example displays the command usage to apply the policy statement which does not allow join messages for group 229.50.50.208/32 and source 192.168.0.0/16 but allows join messages for 192.168.0.0/16, 229.50.50.208 (see Configuring Route Policy Components ):
Example: config>router# pim
 config>router>pim# import join-policy "foo"
config>router>pim# no shutdown
 
The following example displays the PIM configuration:
A:LAX>config>router>pim# info
----------------------------------------------
            import join-policy "foo"
            interface "system"
            exit
            interface "lax-vls"
            exit
            interface "lax-sjc"
            exit
            interface "p1-ix"
            exit
            rp
                static
                    address 2.22.187.237
                        group-prefix 224.24.24.24/3
                    exit
                    address 10.10.10.10

Configuring Multicast Source Discovery Protocol (MSDP) Parameters
Use the following commands to configure basic MSDP parameters:
CLI Syntax: config>router# msdp
peer ip-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 ip-address
receive-msdp-msg-rate number intervalseconds [threshold threshold]
no shutdown
no shutdown
Use the following CLI syntax to configure 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 MSDP configuration:
ALA-48>config>router>msdp# info
-------------------------------------------
         peer 10.20.1.1
             local-address 10.20.1.6
