Usage Guidelines

By default, the interval at which the PIM FW sends Hello messages is 30 seconds.

The command is applicable to PIM-DM and PIM-SM.

The interval at which the PIM FW sends Hello messages should be less than the timeout period of the PIM neighbor. You can run the hello-option holdtime command to set the timeout period of a PIM neighbor.
