Hello message after the router is rebooted or PIM is enabled on an interface. Use
the no form to restore the default value.

seconds - The maximum time before sending a triggered PIM Hello
message. (Range: 0-65535)
Default Setting
5 seconds

Command Usage
• When a router first starts or PIM is enabled on an interface, the hello-interval
is set to random value between 0 and the trigger-hello-interval. This prevents
synchronization of Hello messages on multi-access links if multiple routers are
powered on simultaneously.
• Also, if a Hello message is received from a new neighbor, the receiving router
will send its own Hello message after a random delay between 0 and the
trigger-hello-interval.
Example
