Setting Up Your Multicast Connections
• For IPv4, use the
address-family ipv4
keywords
Step 3
interface all enable
Example:
RP/0/RSP0/CPU0:router(config-mcast-ipv4)# interface all enable
Enables multicast routing and forwarding on all new and existing interfaces.
Step 4 exit
Example:
RP/0/RSP0/CPU0:router(config-mcast-ipv4)# exit
Exits multicast routing configuration mode, and returns the router to the parent configuration mode.
Note For Leaf PEs, if you intend to enable IGMPSN on the bridge domain, ensure that you configure internal querier
inside the IGMPSN profile.
Step 5 router igmp
Example:
RP/0/RSP0/CPU0:router(config)# router igmp
(Optional) Enters router IGMP configuration mode.
Step 6
version {1 | 2 | 3}
Example:
RP/0/RSP0/CPU0:router(config-igmp)# version 3
(Optional) Selects the IGMP version that the router interface uses.
• The default for IGMP is version 3.
• Host receivers must support IGMPv3 for PIM-SSM operation.
• If this command is configured in router IGMP configuration mode, parameters are inherited by all new and existing
interfaces. You can override these parameters on individual interfaces from interface configuration mode.
Step 7 endorcommit
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)# end
or
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)#commit
Saves configuration changes.
• When you issue the end command, the system prompts you to commit changes:
Uncommitted changes found, commit them before exiting(yes/no/cancel)?[cancel]:
• Entering yes saves configuration changes to the running configuration file, exits the configuration session, and
returns the router to EXEC mode.
• Entering no exits the configuration session and returns the router to EXEC mode without committing the
configuration changes.
