Configuring Traffic Behaviors on a Route Receiver

Configuring Traffic Behaviors on a Route Receiver

You can configure different traffic behaviors for different traffic classifiers on a BGP receiver to implement differentiated services.

Context

Do as follows on the BGP route receiver:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run traffic behavior behavior-name

    A traffic behavior is configured and the traffic behavior view is displayed.

  3. Run one of the following commands as needed:

    • To configure CAR actions, run the car { cir cir-value [ pir pir-value ] } [ cbs cbs-value [ pbs pbs-value ] ] [ adjust adjust-vlaue ] [ green { discard | pass [ remark dscp dscp-value | service-class class color color ] } | yellow { discard | pass [ remark dscp dscp-value | service-class class color color ] } | red { discard | pass [ remark dscp dscp-value | service-class class color color ] } ] * [ summary ] [ color-aware ] [ limit-type pps ] command.

    • To re-mark the DSCP value of an IP packet, run the remark [ ipv6 ] dscp { dscp-value | af11 | af12 | af13 | af21 | af22 | af23 | af31 | af32 | af33 | af41 | af42 | af43 | cs1 | cs2 | cs3 | cs4 | cs5 | cs6 | cs7 | default | ef } command.

    • To re-configure the precedence of IP packets, run the remark ip-precedence ip-precedence.

    • To allow all the packets that meet the matching rule to pass, run the permit command.

    • To prevent all the packets that meet the matching rule from passing, run the deny command.

    • To color packets with a certain CoS, run the service-class service-class color color command.

    • To set the class-based HQoS parameters for the specified traffic behavior, run theuser-queue cir cir-value [ [ pir pir-value ] | [ flow-queue flow-queue-name ] | [ flow-mapping mapping-name ] | [ user-group-queue group-name ] | [ service-template service-template-name ] ]* command.

    • To redirect packets to a specified VPN group, run the redirect vpn-group vpn-group-name command.

    • To configure the traffic behavior redirecting to the traffic policy, run the command traffic-policy policy-name.

      NOTE:

      You can run the hierarchical-car enable command in the traffic behavior view of a cascaded traffic policy to enable hierarchical CAR.

      • Cascading a traffic policy over another will cause the device forwarding performance to deteriorate.
      • When the traffic on an interface matches the cascaded traffic policy:
        • The forwarding behavior and cascading a traffic policy are mutually exclusive.
        • If the traffic behaviors in the two traffic policies are different, they can be individually implemented.
        • If the traffic behaviors in the two traffic policies are the same, the specific behavior configuration in the cascaded traffic policy takes effect.
      • On an interface, only one traffic policy can be applied to outgoing or incoming packets. If the traffic policy cascades over another traffic policy and is applied to an interface, both traffic policies take effect on the direction-specific interface.
      • The parameters specified for a traffic policy, such as inbound, outbound, link-layer, mpls-layer, and all-layer, are inherited by the cascaded traffic policy.

      • When the traffic behaviors for two-level ACLs are service-class, level-1 service-class preferentially takes effect. However, if level 1 service-class carries no-remark, level-2 service-class preferentially takes effect.

    • To promote the function effective priority of the traffic behavior, run the command increase-priority.

      The increase-priority command promote the function effective priority of the traffic behavior. After the command is run, the traffic behavior takes effect before BGP Flow Specification service.

  4. Run commit

    The configuration is committed.
