Configuring RIP GR
Network requirements
As shown in Figure 11, 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.

Configuration procedure
Configure IP addresses and subnet masks for interfaces on the switches. (Details not shown.)
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.
Enable RIP GR on Switch A.

Verifying the configuration
# Trigger a routing protocol restart or active/standby switchover and display GR status on Switch A.
