The output shows the NQA test result: the master route is unavailable (the status of the track entry is
Negative), and the backup static route takes effect and Switch A forwards packets to 30.1.1.0/24 through
Switch C.
# When the master route fails, the hosts in 20.1.1.0/24 can still communicate with the hosts in
30.1.1.0/24.
