The IP address of the default gateway of Host A can be configured to be
202.38.160.111.
Normally, Switch A functions as the gateway, but when Switch A is turned off or
malfunctions, 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 switch after recovery.
