PIM-STD/4/NBR_LOSS:The PIM neighbor was lost. (NbrIntIndex=[NbrIntIndex], NbrAddrType=[NbrAddrType], NbrAddr=[NbrAddr], NbrUpTime=[NbrUpTime])


The PIM neighbor was lost.


Parameter Name Parameter Meaning
NbrIntIndex Index of the neighboring interface
NbrAddrType Address type of the neighboring interface
NbrAddr Address of the neighboring interface
NbrUpTime Lifetime of the neighbor relationship

Possible Causes

The PIM neighbor was lost.


  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. 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 messages and contact technical support personnel.
