The Track object to be associated with the policy routing can be a nonexistent

one. After you use the track command to create the Track object, the
association takes effect.
For details of policy routing configuration, refer to

You can associate an interface with a Track object, so that the interface can detect
the status of other interfaces based on that of the Track object and change its
backup status accordingly.
If the status of the Track object is positive, then the link where the detected
■
interface resides works normally, and the detecting interface serves as the
backup interface to backup the detected interface.
If the status of the Track object is negative, then the link where the detected
■
interface resides failed, and the detecting interface turns to the main interface
to take on data transmission.
During the configuration, if the Track object is in the invalid state, it indicates
■
that the Track object association does not take effect yet; each interface keeps
its original forwarding state. After the configuration, if the status of the Track
object turns to invalid, the detecting interface becomes the main interface.
