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 a PIM router sends join/prune messages to its
upstream routers for state update.
•
Joined/Pruned state holdtime—Time for which a PIM router keeps the joined/pruned state for
the downstream interfaces. This joined/pruned state holdtime is specified in a join/prune
message.
•
Multicast source lifetime—Lifetime that a PIM router maintains for a multicast source. If a
router does not receive subsequent multicast data from the multicast source S when the timer
expires, it deletes the (S, G) entry for the multicast source.
You can configure common PIM timers globally for all interfaces in PIM view or for an interface in
interface view. For an interface, the interface-specific configuration takes priority over the global
configuration.
TIP:
As a best practice, use the default settings for a network without special requirements.
