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 outgoing interface, default outgoing interface, 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.
Configuring PBR (using a QoS policy)
Before configuring PBR, complete the following tasks:
• Configure a QoS policy by configuring the match criteria and a redirection action for PBR.
• Apply the QoS policy by defining the occasion to which the PBR applies.
Configuring a QoS policy
Follow these steps to configure traffic redirection:
