This avoids collisionsthat occur when multiple IPv6 PIM routers send hello messages simultaneously.An IPv6 PIM router periodically sends join/prune messages to its upstream for state update. Ajoin/prune message contains the join/prune timeout time. The upstream router sets a join/prune timeouttimer for each pruned downstream interface.Any router that has lost assert election will prune its downstream interface and maintain the assert statefor a period of time. When the assert state times out, the assert loser will resume IPv6 multicastforwarding.When a router fails to receive subsequent IPv6 multicast data from the IPv6 multicast source S, therouter does not immediately delete the corresponding (S, G) entry; instead, it maintains the (S, G) entryfor a period of time, namely the IPv6 multicast source lifetime, before deleting the (S, G) entry.Configuring IPv6 PIM common timers globallyFollow these steps to configure IPv6 PIM common timers globally:To do...
