Command History
Version 8.2.1.0
Version 7.6.1.0
Usage
When an NSF-capable router comes up, it announces the graceful restart capability and
Information
restart duration as a Hello option. The receiving router notes the Hello option. Routers not
NSF-capable discard the unknown Hello option and adjacency is not affected.
When an NSF-capable router goes down, the neighboring PIM speaker preserves the states
and continues the forwarding of multicast traffic while the neighbor router restarts.

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.
