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.
Syntax
ip pim join-filter ext-access-list {in | out}
To remove the access list, use the no ip pim join-filter ext-access-list
{in | out} command.
Parameters
ext-access-list Enter the name of an extended access list.
in Enter this keyword to apply the access list to inbound traffic.
out Enter this keyword to apply the access list to outbound
traffic.
Defaults none
