Configuring a Static RP and Allowing Backward Compatibility
When PIM is configured in sparse mode, you must choose one or more routers to operate as a rendezvous
point (RP) for a multicast group. An RP is a single common root placed at a chosen point of a shared
distribution tree. An RP can either be configured statically in each router, or learned through Auto-RP
or BSR.
This task configures a static RP. For more information about RPs, see the “Rendezvous Points” section
on page MCC-11. For configuration information for Auto-RP, see the “Configuring Auto-RP to
Automate Group-to-RP Mappings” section on page MCC-29.
Step 7
end
or
commit
Example:
RP/0/0/CPU0:router(config-igmp)# end
or
RP/0/0/CPU0:router(config-igmp)# 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.
– Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the
configuration changes to the running configuration
file and remain within the configuration session.
Step 8
show pim [ipv4 | ipv6] group-map [ip-address-name]
[info-source]
Example:
RP/0/0/CPU0:router# show pim ipv4 group-map
(Optional) Displays group-to-PIM mode mapping.
Step 9
show pim [vrf vrf-name] [ipv4 | ipv6] topology
[source-ip-address [group-ip-address] | entry-flag
flag | interface-flag | summary] [route-count]
Example:
RP/0/0/CPU0:router# show pim topology
(Optional) Displays PIM topology table information for
a specific group or all groups.
