Impact on the System

This trap indicates that the neighbor on the virtual link enters the helper state or exits from the helper state. GR failure will affect the normal forwarding of routes.

Possible Causes

1. The neighbor also restarts when it functions as a GR helper.

2. The grace timer expired.

3. The grace LSA was received.


  1. Run the display ospfv3 graceful-restart-information command to check the reason that the local router functions as the GR helper and check the current GR status.
  2. Perform the following operations as required:

    • If the active/standby switchover is performed manually or the OSPFv3 process is restarted in GR mode, go to Step 4.

    • If this trap is generated without any manual operation, go to Step 3.

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