Configure OSPFv3 Graceful Restart (GR) to avoid route flapping and packet loss after an OSPFv3 switch restarts.
After OSPFv3 restarts, the GR restarter and GR helper maintain the neighbor relationship, exchange routing information, synchronize the database, and update the routing table and the forwarding table. This ensures OSPFv3 fast convergence.
Before configuring OSPFv3 GR, configure basic OSPFv3 functions.
