Example for Configuring QPPB (BGP)

This section provides an example for configuring QPPB.

Networking Requirements

On the network shown in Figure 1, router B advertises BGP routes with community attributes to router A, and router A matches the community attributes against the community list, associates traffic behaviors with QoS local IDs for the matched routes, and applies a QPPB local policy to the traffic transmitted along the routes.

Traffic is sent from router B to router C by passing router A. router B functions as a BGP route sender, and router A functions as a BGP route receiver.

It is required that source-based QPPB be applied to the incoming traffic.

Interface 1 and Interface 2 in this example are GE 0/1/0 and GE 0/1/8, respectively.

Figure 1 Networking diagram for configuring QPPB

Precautions

None.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure basic BGP functions.

  2. Configure routing policies to set community attributes for the routes to be advertised and advertise routes on router B.

  3. Apply routing policies to match route attributes and set QoS local ID on router A.

  4. Configure QPPB and apply it to the incoming traffic on router A.

Data Preparation

To complete the configuration, you need the following data:

  • IP address of each interface

  • Routing policy name, matching rule, and route attribute

  • QPPB policy name

Procedure

  1. Configure basic BGP functions on routerA and routerB.

    # Configure loopback interfaces on router A and router B.

[*DeviceB-bgp] peer 1.1.1.1 advertise-community
[*DeviceB-bgp] commit
[~DeviceB-bgp] return

  3. Configure a policy for receiving routes on router A, and apply traffic behaviors to the route that matches the route attribute.

    # Configure a traffic behavior.

    [~DeviceA] traffic behavior dd
[*DeviceA-behavior-dd] remark dscp af11
[*DeviceA-behavior-dd] commit
[~DeviceA-behavior-dd] return

    # Configure a routing policy and apply the traffic behavior to the route that matches the route attribute.

[~DeviceA-localpolicy-ac] return

    # Apply the routing policy to the routes sent from router B on router A.

    <DeviceA> system-view
[~DeviceA] bgp 100
[*DeviceA-bgp] peer 2.2.2.2 route-policy aa import
[*DeviceA-bgp] commit
[~DeviceA-bgp] return

  4. Apply the QPPB local policy to the incoming traffic on router A.

    <DeviceA> system-view

[~DeviceA-GigabitEthernet0/1/8] qppb-policy ac source inbound
[*DeviceA-GigabitEthernet0/1/8] commit
[~DeviceA-GigabitEthernet0/1/8] return

  5. Verify the configuration.

    # Display the QPPB local policy information on router A.

    <~DeviceA> display qppb local-policy configuration ac
qppb local-policy: ac
 statistics disable
 service-class outbound disable
