Configuring common IPv6 PIM timers

IPv6 PIM routers periodically send hello messages to discover IPv6 PIM neighbors, and maintain IPv6
PIM neighbor relationship.
After receiving a hello message, an IPv6 PIM router waits for a random time period before sending a
hello message. This random time period is smaller than the maximum delay for sending hello messages,
and it can avoids collisions that might occur when multiple IPv6 PIM routers send hello messages
simultaneously.
An IPv6 PIM router periodically sends join/prune messages to its upstream routers for state update. A
join/prune message contains the joined/pruned state timeout value, and an upstream router uses this
value to set a timeout timer for the joined state or pruned state of the downstream interfaces.
When a router fails to receive subsequent IPv6 multicast data from the IPv6 multicast source S, the router
does not immediately remove the corresponding (S, G) entry. Instead, it maintains the (S, G) entry for a
period of time (namely, the IPv6 multicast source lifetime) before deleting the (S, G) entry.
You can configure common IPv6 PIM timers in IPv6 PIM view or interface view. The configurations made
in IPv6 PIM view are effective on all interfaces and the configurations made in interface view are effective
