PIM Multicast Routing
– 1935 –
COMMAND MODE
Interface Configuration (VLAN)
COMMAND USAGE
◆ 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.
◆ 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
Console(config-if)#
show ip pim
interface
This command displays information about interfaces configured for PIM.
