PBR and Track
PBR can work with the Track feature to dynamically adapt the availability status of an apply clause to the link status of a tracked object. The tracked object can be a next hop.
When the track entry associated with an object changes to Negative, the apply clause is invalid.
When the track entry changes to Positive or NotReady, the apply clause is valid.
