Network requirements
• Host A wants to access Host B on the Internet, using 202.38.160.111/24 as its default gateway.
• Switch A and Switch B belong to VRRP group 1 with the virtual IP address of 202.38.160.111/24.
• When Switch A operates normally, packets sent from Host A to Host B are forwarded by Switch A;
when Switch A fails, packets sent from Host A to Host B are forwarded by Switch B.
