Impact on the System

The PIM neighbor relationship is disconnected or fails to be established. As a result, the route is unreachable, and data forwarding is interrupted.

The PIM neighbor was lost.

1. Run the ping command to check whether the link between PIM neighbors works properly.

2. Run the display ip routing-table command to check whether the unicast route between PIM neighbors is reachable.

If the unicast route is reachable, go to Step 3.
If the unicast route is unreachable, rectify the route fault to clear the alarm.

3. Run the display this command in the view of the corresponding PIM neighboring interface to check whether the interface is enabled with PIM-SM.

If PIM-SM is enabled on the neighboring interface, PIM neighbor loss is caused by the change of the IP address of the neighboring interface. If the PIM neighbor relationship cannot be re-established after a certain period, go to Step 4.
If PIM-SM is not enabled on the neighboring interface, run the pim sm command in the interface view to enable PIM-SM to clear the alarm.

4. Collect log information and configuration information, and then contact technical support personnel.
