The above information indicates that in standby 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.
If Switch A fails, you can still ping through Host B on Host A. You can use the display
vrrp ipv6 command to view the detailed information of the standby group on Switch B.
# If Switch A fails, the detailed information of standby group 1 on Switch B is displayed.

The above information indicates that if Switch A fails, Switch B becomes the master,
and packets sent from Host A to Host B are forwarded by Switch B.

1.5.2 VRRP Interface Tracking Configuration Example

I. Network requirements
Host A needs to access Host B on the Internet, using FE80::10 as its default
gateway.
Switch A and Switch B belong to standby group 1 with the virtual IP address of
FE80::10.
If Switch A operates normally, packets sent from Host A to Host B are forwarded
by Switch A; if Switch A is in work, but its VLAN-interface 3 which connects to the
Internet is not available, packets sent from Host A to Host B are forwarded by
Switch B.
