Usage Information
The PIM-SM component uses the graceful-restart feature to relearn the PIM JOIN messages (*,G/S,G) from
upstream neighbors. The upstream neighbors detect the RPM failover of the downstream router, on reception of
a different gen-id in the PIM-hello message. They then start to send relevant PIM JOINs to the downstream
router after establishing neighbor-ship with the new active RPM.
ip pim join-filter
Permit or deny PIM Join/Prune messages on an interface using an extended IP access list. This command prevents the PIM-SM router
from creating state based on multicast source and/or group.
