Configuring OSPFv3 GR

NOTE:
You cannot configure OSPFv3 GR after configuring OSPFv3 virtual links because they are not supported
at the same time.
Graceful Restart ensures the continuity of packet forwarding when a routing protocol restarts or a
master/slave switchover occurs:
GR Restarter: Graceful restarting router. It must be Graceful Restart capable.
•
GR Helper: The neighbor of the GR Restarter. It helps the GR Restarter to complete the GR process.
•
To prevent service interruption after a master/slave switchover, a GR Restarter running OSPFv3 must
complete the following tasks:
Keep the GR Restarter forwarding entries stable during reboot
•
Establish all adjacencies and obtain complete topology information after reboot
•
After the master/slave switchover, the GR Restarter sends a Grace-LSA to tell its neighbors that it performs
a GR. Upon receiving the Grace-LSA, the neighbors with the GR Helper capability enter the helper mode
(and are then called "GR Helpers"). Then, the GR Restarter retrieves its adjacencies and LSDB with the
help of the GR Helpers.

Configuring GR Restarter

You can configure the GR Restarter capability on a GR Restarter.
Follow these steps to configure GR Restarter:
To do...
