Configures the frequency with which the device sends PIM hello messages to its neighbors.
By default, the hello-interval is 30 seconds.
PIM Router configuration mode
Use the no hello-interval form of this command to reset the default interval.
Devices use PIM hello messages to advertise themselves as PIM routing devices to their neighbors. At the beginning of an interval, a device sends a hello message, and the timer is reset. The device drops any neighbor that doesn't respond to the message in a period that is 3.5 times the hello interval.
The following example configures the IPv4 PIM hello interval.
device(config)# router pim device(config-pim-router)# hello-interval 50
The following example configures the IPv6 PIM hello interval.
device(config)# ipv6 router pim device(config-ipv6-router-pim-vrf-default-vrf)# hello-interval 50
