join/prune messages to be less than the joined/pruned state holdtime timer.
The following are common timers in IPv6 PIM:
•
Hello interval—Interval at which an IPv6 PIM router sends hello messages to discover IPv6
PIM neighbors and maintain IPv6 PIM neighbor relationship.
•
Triggered hello delay—Maximum delay for sending a hello message to avoid collisions
caused by simultaneous hello messages. After receiving a hello message, an IPv6 PIM router
waits for a random time before sending a hello message. This random time is in the range of 0
to the triggered hello delay.
•
Join/Prune interval—Interval at which an IPv6 PIM router sends join/prune messages to its
upstream routers for state update.
•
Joined/Pruned state holdtime—Time for which an IPv6 PIM router keeps the joined/pruned
state for the downstream interfaces. This joined/pruned state holdtime is contained in a
join/prune message.
•
IPv6 multicast source lifetime—Lifetime that an IPv6 PIM router maintains for an IPv6
multicast source. If a router does not receive subsequent IPv6 multicast data from the IPv6
multicast source S when the timer expires, it deletes the (S, G) entry for the IPv6 multicast
source.
You can configure common IPv6 PIM timers for all interfaces in IPv6 PIM view or for the current
interface in interface view. The configuration made in interface view takes priority over the
configuration made in IPv6 PIM view.
TIP:
As a best practice, use the defaults for a network without special requirements.
Configuring common IPv6 PIM timers globally
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Set the hello interval.
4. Set the join/prune interval.
5. Set the joined/pruned state
holdtime.
6. Set the IPv6 multicast
source lifetime.
Configuring common IPv6 PIM timers on an interface
Step
1. Enter system view.
2. Enter interface view.
