The IP address of the default gateway of Host A is configured as 202.38.160.111. 

Normally, Switch A functions as the gateway, but when Switch A is turned off or fails, Switch B will 

function as the gateway instead. 

Configure Switch A to operate in preemptive mode, so that it can resume its gateway function as the 

master after recovery. 

Even when Switch A is still functioning, Switch B (with another link to connect with the outside) can 

function as a gateway when the interface on Switch A and connecting to Internet does not function 

properly. This can be implemented by enabling the VLAN interface tracking function. 

The VRRP group ID is set to 1, with configurations of authorization key and timer.
