Network requirements
As shown in
Host A is 10.1.1.10/24.
Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
When Switch A works normally, packets from Host A to Host B are forwarded through Switch A.
When VRRP detects that there is a fault on the uplink interface of Switch A through the interface
management module, packets from Host A to Host B are forwarded through Switch B.
