Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

NbrIntIndex

Indicates the index of a neighbor.

NbrAddrType

Indicates the inetAddressType of neighbor address. The value can be:
  • 1: IPv4 address

  • 2: IPv6 address

NbrAddr

Indicates the address of a neighbor.

NbrUpTime

Indicates the period during which the neighbor relationship is in the Up state.

NbrIntName

Indicates the name of the neighbor interface.

InstanceID

Indicates the ID of the instance to which the neighbor interface belongs.

InstanceName

Indicates the name of the instance to which the neighbor interface belongs.

NeighborLossReason

Indicates a possible cause for PIM neighbor loss.
  • 1: The neighbor relationship expires.

  • 7: Hello messages with the holdtime 0 are received.

  • 8: The BFD session goes Down.

  • 9: A user manually tears down the PIM neighbor relationship.

Impact on the System

The PIM neighbor is disconnected, which has impact on multicast services.

Possible Causes

1. The timer of the PIM neighbor expired.

2. The router received a Hello message with the Holdtime value being 0.

Procedure

  1. Run the display pim interface interface-type interface-number command on the neighboring router to check whether PIM is enabled on the interface that connects the local router.

    • If so, go to Step 3.

    • If not, go to Step 2.

  2. Run the pim dm or pim sm command on the interface that connects the local router to enable PIM. Run the display pim neighbor neighbor-address command on the neighboring router to check whether the PIM neighbor of the local router is established.

    • If so, go to Step 6.

    • If not, go to Step 3.

  3. Run the display ip routing-table ip-address command on the neighboring router to check whether the route to the local router exists.

    • If so, go to Step 5.

    • If not, go to Step 4.

  4. Confirm that no unicast route is faulty. Run the display pim neighbor neighbor-address command on the neighboring router to check whether the PIM neighborship is established between the local router and its neighbor.

    • If so, go to Step 6.

    • If not, go to Step 5.

  5. Collect alarm information and configuration information, and then contact technical support personnel.
  6. End.
