BGP/2/hwBgpPeerRouteNumThresholdExceed_active

Message

BGP/2/hwBgpPeerRouteNumThresholdExceed_active: The number of routes received from the BGP peer exceeded the alarm threshold. (InstanceId=[InstanceId], Afi=[AddrFamilyAfi], Safi=[AddrFamilySafi], PeerRemoteAddrType=[PeerIPAddrType], PeerRemoteAddr=[PeerIPAddr], MaxRouteNumber=[RouteLimitNum], AlarmThreshold=[RouteLimitThreshold])

Description

The number of routes received from the BGP peer who configed with route-limit, exceeds the alarm threshold which is configured.

AlarmThreshold

Alarm threshold

Possible Causes

Cause: The number of routes received by a BGP device configured with the peer route-limit limit percentage command from its peer exceeded the upper threshold.

Procedure

  • Cause: The number of routes received by a BGP device configured with the peer route-limit limit percentage command from its peer exceeded the upper threshold.
    1. Run the display bgp peer command to check whether the number of routes received from a peer exceeds the value obtained the maximum number of routes that can be received from the peer multiplied by the alarm threshold(%).

      • If the number of routes received from the peer exceeds the value, go to Step 2.
      • If the number of routes received from a peer does not exceed the value, go to Step 9.

    2. Check whether the routes received from the peer are necessary ones.

      • If the routes received from the peer are necessary ones, go to Step 8.
      • If the routes received from the peer are not necessary ones, go to Step 3.

    3. View user log information to check whether a large number of unnecessary routes are received because the local import policy is modified using commands such as peer route-policy, peer ip-prefix, and peer filter-policy.

      • If a large number of unnecessary routes are received because the local import policy is modified, go to Step 4.
      • If a large number of unnecessary routes are received due to other reasons, go to Step 5.

    4. Update the local import policy by using the commands such as the peer route-policy command, the peer ip-prefix command, and the peer filter-policy command to deny the unnecessary routes. Then, check whether the problem is solved.
    5. Contact the maintenance engineer responsible for the remote device to check whether the routes sent by the remote device to the local device are necessary ones.

      • If the routes sent by the remote device to the local device are necessary ones, go to Step 7.
      • If the routes sent by the remote device to the local device are not necessary ones, go to Step 6.

    6. Request the maintenance engineer responsible for the remote device to modify the policy for importing routes or the policy for advertising routes to withdraw the unnecessary routes. Then, check whether the fault is rectified.
    7. Request the maintenance engineer responsible for the remote device to configure route aggregation to reduce the number of routes to be advertised. Then, check whether the fault is rectified. If the fault persists, go to Step 9.
    8. Increase the maximum number of routes that can be received from the peer. Then, check whether the fault is rectified.
    9. Collect the alarm information, log information, and configuration information, and then contact technical support personnel technical support personnel.
