Configuring Common Pim Timers - HP MSR ASM Configuration Manual

To set the prune delay timer:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Set the prune delay timer.

Configuring common PIM timers

PIM routers discover PIM neighbors and maintain PIM neighboring relationship with other routers by
periodically sending hello messages.
After receiving a hello message, a PIM router waits a random period, which is smaller than the maximum
delay between hello messages, before sending a hello message. This delay avoids collisions that occur
when multiple PIM routers send hello messages simultaneously.
A 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 losers will resume multicast forwarding.
When a router fails to receive subsequent multicast data from 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 multicast source lifetime) before deleting the (S, G) entry.
NOTE:
If no special networking requirements are raised, use the default settings for the timers.
