PIM_1.3.6.1.4.1.2011.5.25.149.4.0.27 hwPimBasNeighborLoss

Trap Buffer Description

PIM neighbor loss. (NbrIntIndex=[NbrIntIndex], NbrAddrType=[NbrAddrType], NbrAddr=[NbrAddr], NbrUpTime=[NbrUpTime], NbrIntName=[NbrIntName], InstanceID=[InstanceID], InstanceName=[InstanceName], NeighborLossReason=[NeighborLossReason])

After receiving a Hello message from a neighbor, a device recorded information about this neighbor and started a timer for this neighbor. If the device received no Hello packet before the timer expired, the device considered the neighbor lost, and thereby reported a trap message.

Procedure

1. Run the ping or ping ipv6 command to check whether the link between PIM neighbors is Up.

If the link is Up, go to Step 4.
If the link is Down, go to Step 2.

2. Run the display ip routing-table or display ipv6 routing-table command to check whether the unicast route from the local device to the neighbor works properly.

If the route works properly, go to Step 3.
If the route works improperly, you can clear the alarm by rectifying the routing fault.

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, the IP address of the neighboring interface changes.
If PIM-SM is not enabled on the neighboring interface, configure the interface enable with PIM-SM.

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