Join/Prune Period
The timer for the join/prune period determines how often the router sends out
periodic join/prunes. These messages renew the router's membership in
groups for which it must forward multicasts. They also prune the router from
trees for which it no longer needs traffic. The router constructs the join/prune
packet and determines through which interfaces to transmit it as described in
"Sending Periodic Join/Prune Packets" on page 13-24.
You configure the join/prune period from the PIM sparse configuration mode
context. See Table 13-2 for the exact command syntax.
You set the other timers for individual interfaces.
