Configuring the PIM for IPv4 Join/Prune Message Interval

When you use the router for PIM, the router sends join/prune messages to the upstream RPF neighbor. The default join/prune message interval is 60 seconds. You can configure the join/prune message interval using the ip pim join-prune-interval command. The ip pim join-prune-interval command in Router Configuration mode configures the join-prune interval on all the PIM interfaces on the router. To override this global setting on a particular interface, use the ip pim join-prune-interval command in Interface Configuration mode.

The hold-time associated with the PIM join/prune interval messages is 3.5 times the PIM join/prune message interval.

Note: You cannot configure the PIM join/prune message interval on PIM DM interfaces.

• To set an interval value, in the range 10–210 seconds, at which the router sends the PIM join/prune message, issue the ip pim join-prune-interval command.

  In Router Configuration mode:

  host1(config-router)#ip pim join-prune-interval 150

  The no version restores the default value, 60 seconds.

  In Interface Configuration mode:

  host1(config-subif)#ip pim join-prune-interval 150

  The no version restores the value that is specified in Router Configuration mode.
