PIM/4/BAS_NBR_LOSS

Message

PIM/4/BAS_NBR_LOSS: PIM neighbor loss. (NbrIntIndex=[NbrIntIndex], NbrAddrType=[NbrAddrType], NbrAddr=[NbrAddr], NbrUpTime=[NbrUpTime], NbrIntName=[NbrIntName], InstanceID=[InstanceID], InstanceName=[InstanceName], NeighborLossReason=[NeighborLossReason])

Description

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.

Parameters

Parameter Name	Parameter Meaning
NbrIntIndex	Index of the interface where the neighbor relationship is established.
NbrAddrType	Address type of the neighboring interface: MIB_ADDRESSTYPE_UNKNOWN = 0, MIB_ADDRESSTYPE_IPV4 = 1, MIB_ADDRESSTYPE_IPV6 = 2, MIB_ADDRESSTYPE_IPV4Z = 3, MIB_ADDRESSTYPE_IPV6Z= 4, MIB_ADDRESSTYPE_DSN = 16, MIB_ADDRESSTYPE_MAX
NbrAddr	Neighbor address.
NbrUpTime	Time since the neighbor relationship is established.
NbrIntName	Name of the interface where the neighbor relationship is established.
InstanceID	Instance index.
InstanceName	Instance name.
NeighborLossReason	Reason why the neighbor relationship is unavailable.

Possible Causes

The hold timer of the neighbor relationship expired.

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.
