The output shows the BFD detection result: the next hop 10.2.1.2 is reachable (the status of the track entry
is Positive), and the master static route takes effect. Router A forwards packets to 30.1.1.0/24 through
Router B.

The output shows the BFD detection result: if the next hop 10.2.1.2 is unreachable (the status of the track
entry is Negative), the backup static route takes effect, and Router A forwards packets to 30.1.1.0/24
through Router C and Router B.
