Overview
QoS policy routing is a technique used to make routing decisions based on user-defined QoS policies.
Different from destination-based routing, QoS policy routing makes routing decisions based on the
source address and other criteria. For more information about QoS policies, see ACL and QoS
Configuration Guide.
QoS policy routing takes precedence over destination-based routing. If a packet meets the match criteria,
QoS policy routing applies; otherwise, destination-based routing applies.

For more information about the configuration commands used in this section, see ACL and QoS
Command Reference.
Configuring a QoS policy
To configure a QoS policy:
Step Command
1. Enter system view. system-view
2. Create a class and enter class view. traffic classifier tcl-name [ operator { and | or } ]
3. Configure match criteria. if-match match-criteria
4. Exit to system view. quit
5. Create a traffic behavior and enter traffic
behavior view.
traffic behavior behavior-name
6. Configure the action of redirecting traffic
to the next hop.
redirect next-hop { ipv4-add1 [ track track-entry-number ]
[ ipv4-add2 [ track track-entry-number ] ] | ipv6-add1
[ interface-type interface-number ] [ track track-entry-number ]
[ ipv6-add2 [ interface-type interface-number ] [ track
track-entry-number ] ] } [ fail-action { discard | forward } ]
7. Exit to system view. quit
8. Create a QoS policy and enter QoS
policy view.
