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.

1.4.2 VRRP Interface Tracking Configuration Example

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