# Configuring the PIM Join/Prune Message Interval

When you use the router for PIM, the router sends join/prune message to the upstream RPF neighbor. The default join/prune message interval is 60 seconds. You can configure the join/prune message interval using the ipv6 pim join-prune-interval command. The ipv6 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 ipv6 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 dense mode interfaces.

ipv6 pim join-prune-interval

- Use to set an interval value, in the range 10–210 seconds, at which the router sends the PIM join/prune message; the default value is 60 seconds.
- Examples

  In Router Configuration mode:

  host1(config-if)#ipv6 pim join-prune-interval 150

  In Interface Configuration mode:

  host1(config-subif)#ipv6 pim join-prune-interval 150
- Use the no version to restore the default value, 60 seconds.
