RIPng GR configuration example
Network requirements
As shown in Figure 98, Switch A, Switch B, and Switch C learn IPv6 routing information through RIPng.
Configure Switch A as the GR restarter. Configure Switch B and Switch C as the GR helpers to synchronize their routing tables with Switch A by using GR.

Configuration procedure
Configure IPv6 addresses for interfaces. (Details not shown.)
Configure RIPng on the switches to ensure the following: (Details not shown.)
Switch A, Switch B, and Switch C can communicate with each other at Layer 3.
Dynamic route update can be implemented among them with RIPng.
Enable RIPng GR on Switch A.
<SwitchA> system-view [SwitchA] ripng 1 [SwitchA-ripng-1] graceful-restart
Verifying the configuration
# Restart RIPng process 1 on Switch A.
[SwitchA-ripng-1] return <SwitchA> reset ripng 1 process Reset RIPng process? [Y/N]:y
# Display GR information on Switch A.
<SwitchA> display ripng 1 graceful-restart RIPng process: 1 Graceful Restart capability : Enabled Current GR state : Normal Graceful Restart period : 60 seconds Graceful Restart remaining time: 0 seconds
