Version Description
9.9(0.0) Introduced on the C9010.

7.6.1.0 Introduced on the E-Series.
Usage
Information
When an NSF-capable router comes up, it announces the graceful restart capability and 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.
C9000 Series
Syntax
ip pim join-filter ext-access-list
To remove the access list, use the no ip pim join-filter ext-access-list command.
Parameters
ext-access-list Enter the name of an extended access list.
Defaults none
