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. Use the display vrrp
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.

1.4.2 VRRP Interface Tracking Configuration Example
I. Network requirements
z Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its
default gateway.
z Switch A and Switch B belong to standby group 1 with the virtual IP address of
202.38.160.111.
z 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
