ip pim graceful-restart
This feature permits configuration of non-stop forwarding (NSF or graceful restart) capability of a PIM router to its
neighbors.
E-Series
Syntax [ipv6] ip pim graceful-restart {helper-only | nsf [restart-time
| stale-entry-time]}
Parameters
ipv6 Enter the keyword
ipv6
to enable graceful-restart for the IPv6
multicast routes.
helper-only Enter the keywords
helper-only
to configure as a receiver
(helper) only by preserving the PIM status of a graceful restart PIM
neighboring router.
nsf Enter the keyword
nsf
to configure the non-stop forwarding
capability.
restart-time (OPTIONAL) Enter the keywords
restart-time
followed by the
number of seconds estimated for the PIM speaker to restart. The
range is 30 to 300 seconds. The default is 180 seconds.
stale-entry-time (OPTIONAL) Enter the keywords
stale-entry-time
followed by
the number of seconds for which entries are kept alive after restart.
The range is 30 to 300 seconds. The default is 60 seconds.
Defaults as above

ipv6
option for the
E-Series.
Version 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.
