Requirements
Switch A is the master and Switch B is the backup in a VRRP group. Both Switch A
and Switch B have an interface connected with the Internet. Configure the VRRP
interface tracking function, so that when the interface connected with the
Internet on Switch A becomes unavailable, Switch B can replace Switch A to act as
the gateway even if Switch A is still working.
Set the group number to 1.
