6.9.2 Enabling OSPFv3 GR

After an OSPFv3 process restarts through GR, the Restarter and the Helper reestablish the
neighbor relationship, exchange routing information, synchronize the LSDB, and update the
routing table and forwarding table. These operations help ensure OSPFv3 fast convergence and
stabilize the network topology.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospfv3 process-id
The OSPFv3 view is displayed.
Step 3 Run:
graceful-restart [ period period | ack-time time | retransmit-interval interval |
lsa-checking-ignore | planned-only ]
OSPFv3 GR is enabled.
By default, OSPFv3 GR is disabled.
ack-time is optional. After ack-time is specified, the restarter can discover more neighbors in
the time period.

6.9.3 Enabling the Helper of OSPFv3 GR
The GR Helper, which is a neighbor of the GR Restarter, can identify GR signaling, maintain
the adjacency with the Restarter during the active/standby switchover of the Restarter, and help
the Restarter to restore the network topology.
