Configuring Ipv6 Pim Common Timers - HP 6125G Configuration Manual

Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the prune delay
interval.

Configuring IPv6 PIM common timers

IPv6 PIM routers discover IPv6 PIM neighbors and maintain IPv6 PIM neighboring relationships with
other routers by periodically sending hello messages.
After receiving a hello message, an IPv6 PIM router waits a random period, which is smaller than the
maximum delay between hello messages, before sending a hello message. This avoids collisions that
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. A join/prune
message contains the join/prune timeout time. 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.
