The default gateway of 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 operates properly, packets from Host A to Host B are forwarded through Switch A. When VRRP detects that a fault is on the uplink interface of Switch A through the interface management module, packets from Host A to Host B are forwarded through Switch B. 207

•
As shown in
Figure 54
, Host A needs to access Host B on the Internet. The default gateway of 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 operates properly, packets from Host A to Host B are forwarded through Switch A.
When VRRP detects that a fault is on the uplink interface of Switch A through the interface
management module, packets from Host A to Host B are forwarded through Switch B.
