Configuring common PIM timers

IMPORTANT:
To prevent the upstream neighbors from aging out, you must configure the interval for sending
join/prune messages to be less than the joined/pruned state holdtime timer.
The following are common timers in PIM:
•
Hello interval—Interval at which a PIM router sends hello messages to discover PIM
neighbors, and maintain 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, a PIM router waits
