3) Verify the configuration
After the configuration, Host B can be pinged successfully on Host A. To verify your
configuration, use the display vrrp ipv6 verbose command.

The above information shows that in VRRP group 1 Switch A is the master, Switch B is the
backup and packets sent from Host A to Host B are forwarded by Switch A.
When Switch A fails, you can still successfully ping Host B on Host A. To view the detailed
information of the VRRP group on Switch B, use the display vrrp ipv6 verbose command.
# When Switch A fails, the detailed information of VRRP group 1 on Switch B is displayed.
