Configuring RIP GR

As shown in Figure 10, Switch A, Switch B, and Switch C all run RIPv2.

• Enable GR on Switch A. Switch A acts as the GR restarter.

• Switch B and Switch C act as GR helpers to synchronize their routing tables with Switch A by using GR.

1. Configure IP addresses and subnet masks for interfaces on the switches. (Details not shown.)

2. Configure RIPv2 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 RIPv2.

3. Enable RIP GR on Switch A.

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

# Restart RIP process 1 on Switch A.

[SwitchA-rip-1] return
<SwitchA> reset rip 1 process
Reset RIP process? [Y/N]:y

# Display GR status on Switch A.
