3. Set the interval to send hello
messages.
pim timer hello interval
By default, the interval to send
hello messages is 30 seconds.
4. Set the maximum delay for
sending a hello message.
pim triggered-hello-delay delay
By default, the maximum delay for
sending a hello message is 5
seconds.
5. Set the interval to send
join/prune messages.
pim timer join-prune interval
By default, the interval to send
join/prune messages is 60
seconds.
6. Set the joined/pruned state
holdtime timer.
pim holdtime join-prune time
By default, the joined/pruned state
holdtime timer is 210 seconds.
Setting the maximum size of each join or prune message
The loss of an oversized join or prune message might result in loss of massive information. You can set a
small value for the size of each join or prune message to reduce the impact.

Enabling PIM to work with BFD
PIM uses hello messages to elect a DR for a shared-media network. The elected DR is the only multicast
forwarder on the shared-media network.
If the DR fails, a new DR election process will start after the DR ages out. However, it might take a long
period of time before other routers detect the link failures and trigger a new DR election. To start a new
DR election process immediately after the original DR fails, enable PIM to work with BFD on a
shared-media network to detect failures of the links among PIM neighbors. You must enable PIM to work
with BFD on all PIM-capable routers on a shared-media network, so that the PIM neighbors can fast
