Configuring join/prune interval

Configure the interval at which the router will send periodic PIM-SM join or prune interval messages.

You must be in the PIM configuration context, as indicated by the switch(config-pim)# prompt.
Configure the join/prune interval using the following command.

join-prune-interval <INTERVAL-VALUE>

For example, the following command sets the join/prune interval to 400 seconds:
switch# configure terminal
switch(config)# router pim
switch(config-pim)# join-prune-interval 400

The no form of the command sets the interval to the default of 60 seconds.
