The output information above indicates the NQA test 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 

, the next hop of the static route from Switch A to Switch C is Switch B. 

z 

Configure Static Routing-Track-BFD collaboration on Switch A to implement real-time monitoring 

of the validity of the static route to Switch C.

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

 Figure 1-6

. The configuration procedure is 

omitted. 

2)  Configure a static route on Switch A and associate it with the track entry. 

# Configure the address of the next hop of the static route to Switch C as 10.2.1.1, and configure the 

static route to associate with track entry 1.

[SwitchA] ip route-static 10.1.1.2 24 10.2.1.1 track 1 

3)  Configure basic BFD functions on Switch A.
