OSPFv3 GR configuration example
Network requirements
As shown in Figure 108:
Switch A, Switch B, and Switch C that reside in the same AS and the same OSPFv3 routing domain are GR capable.
Switch A acts as the GR restarter. Switch B and Switch C act as the GR helpers, and synchronize their LSDBs with Switch A through GR.

Configuration procedure
Configure IPv6 addresses for interfaces. (Details not shown.)
Configure basic OSPFv3:
# On Switch A, enable OSPFv3 process 1, enable GR, and set the router ID to 1.1.1.1.
<SwitchA> system-view [SwitchA] ospfv3 1 [SwitchA-ospfv3-1] router-id 1.1.1.1 [SwitchA-ospfv3-1] graceful-restart enable [SwitchA-ospfv3-1] quit [SwitchA] interface vlan-interface 100 [SwitchA-Vlan-interface100] ospfv3 1 area 1 [SwitchA-Vlan-interface100] quit
# On Switch B, enable OSPFv3 and set the router ID to 2.2.2.2. (By default, GR helper is enabled on Switch B.)
<SwitchB> system-view [SwitchB] ospfv3 1 [SwitchB-ospfv3-1] router-id 2.2.2.2 [SwitchB-ospfv3-1] quit [SwitchB] interface vlan-interface 100 [SwitchB-Vlan-interface100] ospfv3 1 area 1 [SwitchB-Vlan-interface100] quit
# On Switch C, enable OSPFv3 and set the router ID to 3.3.3.3. (By default, GR helper is enabled on Switch C.)
<SwitchC> system-view [SwitchC] ospfv3 1 [SwitchC-ospfv3-1] router-id 3.3.3.3 [SwitchC-ospfv3-1] quit [SwitchC] interface vlan-interface 100 [SwitchC-Vlan-interface100] ospfv3 1 area 1 [SwitchC-Vlan-interface100] quit
Verifying the configuration
# Perform a master/backup switchover on Switch A to trigger an OSPFv3 GR operation. (Details not shown.)
