OSPFv3 GR configuration example
Network requirements
As shown in Figure 93:
• 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
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. 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
