Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

InstanceId

Indicates the index of the instance to which the peer belongs.

Afi

Indicates the address family:
  • 1: ipv4

  • 2: ipv6

  • 25: vpls

  • 196: l2vpn

Safi

Indicates the sub-address family:
  • 1: unicast

  • 2: multicast

  • 4: mpls

  • 5: mvpn

  • 65: vpls

  • 66: mdt

  • 70: evpn

  • 128: vpn

  • 245: tunnel-encap-ext

PeerType

Indicates the address type of the peer:
  • 1: ipv4

  • 2: ipv6

PeerRemoteAddr

Indicates the address of the peer.

GrStatus

Indicates the GR status of the peer:
  • 1: peerNotBeingHelped

  • 2: peerRestarting

  • 3: peerFinishRestart

  • 4: peerHelping

Impact on the System

  • If an alarm of the type peerNotBeingHelped(1) is generated, it indicates that the local end fails to function as the GR Helper during the restart of the BGP peer. As a result, services will be interrupted until the peer session is reestablished and all routes are converged.

  • If an alarm of the type peerRestarting(2) is generated, it indicates that the local end detects that the BGP peer is performing graceful restarting. When the routing protocol on which BGP route iteration depends has the GR capability, services will not be affected. Otherwise, services will be interrupted.

  • If an alarm of the type peerFinishRestart(3) is generated, it indicates that the BGP peer session becomes normal. In this case, no services will be affected.

  • If an alarm of the type peerHelping(4) is generated, it indicates that the BGP peer is helping the local end to perform GR. When the routing protocol on which BGP route iteration depends has the GR capability, services will not be affected. Otherwise, services will be interrupted.

Possible Causes

The GR status of either BGP peer that succeeded in the GR capability negotiation changed.

Procedure

  1. Do as follows according to the value of the parameter GrStatus:

    • If an alarm of the type peerNotBeingHelped(1) is generated, it indicates that the BGP peer will not be helped during restarting. Then, go to Step 4.

    • If an alarm of the type peerRestarting(2) is generated, it indicates that the BGP peer is detected restarting. Then, go to Step 2.

    • If an alarm of the type peerFinishRestart(3) is generated, it indicates that the BGP peer finishes the latest GR. In this case, no action is required. Then, go to Step 5.

    • If an alarm of the type peerHelping(4) is generated, it indicates that the BGP peer is helping the local end to perform GR. Then, go to Step 3.

  2. Run the display ip routing-table ipv4-address command to check whether the address of the peer exists.

    • If so, it indicates that the local end is performing GR. In this case, no services will be affected, and no action is required. Then, go to Step 5.

    • If not, go to Step 4.

  3. During GR, active/standby switchover is complete. In this case, you need to check whether the local end performs active/standby switchover actively.

    • If so, go to Step 5.

    • If not, go to Step 4.

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