The output information above indicates the BFD detection result, that is, the next hop 10.2.1.1 is 

unreachable (the status of the track entry is Negative), and the configured static route is invalid. 

z 

As shown in 

, Host A needs to access Host B on the Internet. The default gateway of 

Host A is 10.1.1.10/24. 

z 

Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 10.1.1.10. 

z 

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.

1)  Configure the IP address of each interface as shown in 

.  

2)  Configure a track entry on Switch A. 

# Configure track entry 1, and associate it with the physical status of the uplink interface VLAN-interface
