RIPng GR configuration example

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.

1. Configure IPv6 addresses for interfaces. (Details not shown.)

2. 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.

3. Enable RIPng GR on Switch A.

   <SwitchA> system-view
   [SwitchA] ripng 1
   [SwitchA-ripng-1] graceful-restart
   

# 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
