PBR and track

Associated with a track object, PBR can sense topology changes faster. You can associate PBR with a

track entry when configuring the next hop and default next hop to dynamically determine link

reachability. The PBR configuration takes effect when the status of the associated track object is Positive
or Invalid.

NOTE:

For more information about track-PBR collaboration, see

High Availability Configuration Guide.
