Hello message after the router is rebooted or PIM is enabled on an interface. Use

Command Usage
â—† When a router first starts or PIM is enabled on an interface, the hello delay is set
to random value between 0 and the trigger-hello-delay. This prevents
synchronization of Hello messages on multi-access links if multiple routers are
powered on simultaneously.
â—† 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-delay.
Example
Console(config-if)#ip pim trigger-hello-delay 3

vlan-id - VLAN ID (Range: 1-4094)
Command Mode
Normal Exec, Privileged Exec
Command Usage

the preceding pages. It also shows the address of the designated PIM router and
