Parameters

interval	Specifies the interval for sending Hello messages.	The value is an integer that ranges from 1 to 18000, in seconds.

Default Level

Usage Guidelines

By default, the interval for sending Hello messages on an interface is 30 seconds.

This command is valid for both PIM-DM and PIM-SM.

The interval for sending Hello messages must be shorter than the timeout period of PIM neighbors. You can run the hello-option holdtime command to set the timeout period of PIM neighbors.

The configuration is the same as the timer hello command in the PIM view, except for the view. The system prefers the configuration in the interface view. The value configured in the PIM view is used if no value is configured on the interface.

You must run the multicast routing-enable command to enable the multicast function before using the command.

Example

# Set the interval for sending Hello messages to 40 seconds on GE 1/0/0.

<sysname> system-view
[sysname] multicast routing-enable
[sysname] interface GigabitEthernet 0/0/0
[sysname-GigabitEthernet0/0/0] pim timer hello 40
