The pim ipv6 triggered-hello-delay command sets the maximum delay for triggering Hello messages.
The undo pim ipv6 triggered-hello-delay command restores the default maximum delay.
By default, the maximum delay for triggering Hello messages is 5 seconds.
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies the maximum delay for triggering Hello messages. | The value is an integer that ranges from 1 to 5, in seconds. |

Usage Scenario
Conflicts will occur if multiple PIM devices sending Hello message at the same time. To avoid such conflicts, when a PIM device detects Hello messages on the network, it waits for a random delay that is smaller than the value configured using this command before sending a Hello message.
To avoid the conflict caused by multiple PIM devices sending Hello message at the same time, the PIM device automatically selects a random number smaller than the configured value as the delay. When detecting Hello messages in the network, the PIM device sends Hello message after the delay.
