◆ The pruned state times out approximately every three minutes and the
entire PIM-DM network is reflooded with multicast packets and prune
messages. The state refresh feature keeps the pruned state from
timing out by periodically forwarding a control message down the
distribution tree, refreshing the prune state on the outgoing interfaces
of each router in the tree. This also enables PIM routers to recognize
topology changes (sources joining or leaving a multicast group) before
the default three-minute state timeout expires.
