Configuring PIM Message Intervals

Router query messages are used to elect the PIM DR. The PIM DR is responsible for sending router

query messages. By default, router query messages are sent every 30 seconds. You can change this value

by entering the following command:

hostname(config-if)# pim hello-interval seconds

Valid values for the seconds argument range from 1 to 3600 seconds.

Every 60 seconds, the FWSM sends PIM join/prune messages. To change this value, enter the following

hostname(config-if)# pim join-prune-interval seconds

Valid values for the seconds argument range from 10 to 600 seconds.
