59.4 VRRPv3 Troubleshooting

When configuring and using VRRP v3 protocol, it might operat e abnormally because of incorrect physical
connections and configuration. So, users should pay attention to the following points:

First, the physical connections should be correct;

Next, the interface and link protocol are UP (use show ipv6 interface command);

And then, make sure that IP v6 forwarding function is enabled (use ipv6 enable command);

Besides, make sure that VRRP v3 protocol is enable on the interface;

Check whether the time of timer in different routers (or layer-three Ethernet switch) within the same
backup group is the same;

Check whether the virtual IP v6 addresses in the same backup group is the same.
