HP MSR ASM Configuration Manual page 351

An IPv6 PIM router periodically sends join/prune messages to its upstream for state update. A join/prune
message contains the join/prune timeout timer. The upstream router sets a join/prune timeout timer for
each pruned downstream interface.
Any router that has lost assert election will prune its downstream interface and maintain the assert state
for a period of time. When the assert state times out, the assert loser will resume IPv6 multicast
forwarding.
When a router fails to receive subsequent IPv6 multicast data from the IPv6 multicast source S, the router
does not immediately delete 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.
NOTE:
If no special networking requirements are raised, use the default settings for the timers.
Configuring common IPv6 PIM timers globally
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the hello interval.
4. Configure the join/prune
interval.
5. Configure the join/prune
timeout timer.
6. Configure assert timeout
timer.
7. Configure the IPv6 multicast
source lifetime.
Configuring common IPv6 PIM timers on an interface
Step
1. Enter system view.
2. Enter interface view.
Configure the hello interval.
3.
4. Configure the maximum delay
between hello messages.
5. Configure the join/prune
interval.
6. Configure the join/prune
timeout timer.
