Usage Guidelines
Usage Scenario
PIM devices periodically send Hello messages to maintain PIM neighbor relationships. You can run the pim timer hello command to set the interval for sending Hello messages.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Precautions
The interval for sending Hello messages must be shorter than the timeout period of PIM neighbors. You can run the hello-option holdtime (IPv4) command to set the timeout period of PIM neighbors.
The configuration is the same as the timer hello (IPv4) 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.
