Impact on the System

The PIM neighbor relationship is interrupted or fails to be established, the route is unreachable, and service data forwarding is interrupted.

Possible Causes

Cause 1: The link was faulty.

Cause 2: The neighboring device failed.

Cause 3: The protocol configuration of the neighboring device was incorrect.

Procedure

  • Cause 1: The link was faulty.
    1. Run the ping command to check whether the link between PIM neighbors works properly.

      • If the link works properly, go to Step 3.
      • If the link works improperly, go to Step 2.

    2. Collect the alarm information, log information, and configuration information, and then contact technical support personnel.
    3. End.
  • Cause 2: The neighboring device failed.
    1. 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 2.
      • If the unicast route is unreachable, rectify the route fault to clear the alarm.

    2. End.
  • Cause 3: The protocol configuration of the neighboring device was incorrect.
    1. 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 2.
      • 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.

    2. Collect the alarm information, log information, and configuration information, and then contact technical support personnel.
