Multicast Routing Commands 4

ip pim trigger-hello-interval

This command configures the maximum time before transmitting a triggered PIM Hello message after the router is rebooted or PIM is enabled on an interface. Use the no form to restore the default value.

Syntax

ip pim triggerr-hello-interval seconds no ip pim triggerr-hello-interval

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

Default Setting

5 seconds

Command Mode

Interface Configuration (VLAN)

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

Console(config-if)#ip pim triggerr-hello-interval 10

Console(config-if)#

ip pim join-prune-holdtime

This command configures of the hold time for the prune state. Use the no form to restore the default value.

Syntax

ip pim join-prune-holdtime seconds no ip pim join-prune-holdtime

seconds - The hold time for the prune state. (Range: 0-65535)

Default Setting

210 seconds

Command Mode

Interface Configuration (VLAN)

4-311
