The output shows the following when an active/standby switchover occurs on Switch S:
• The neighbor relationships and routing information on Switch A and Switch B have not
changed.
• The traffic from Switch A to Switch B has not been impacted.
Configuring RIPng FRR
Network requirements
As shown in Figure 97, Switch A, Switch B, and Switch C run RIPng. Configure RIPng FRR so that
when Link A becomes unidirectional, traffic can be switched to Link B immediately.
