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
on page
Automate Group-to-RP Mappings" section on page
OL-
MCC-11. For configuration information for Auto-RP, see the
How to Implement Multicast Routing
Purpose
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.
(Optional) Displays group-to-PIM mode mapping.
(Optional) Displays PIM topology table information for
a specific group or all groups.
