QPPB configuration examples
QPPB configuration example in an IPv4 network
Network requirements
As shown in Figure 24 , all switches run BGP. Device B receives routes, sets the QPPB QoS-local IDs, and
uses the QoS policy to limit the traffic from Device B to Device A to 512 kbps.

Configuration procedure
1. Configure IP addresses for each interface (omitted)
2. Configure Device A
# Configure a BGP connection.
<DeviceA> system-view
[DeviceA] bgp 1000
[DeviceA-bgp] peer 168.1.1.2 as-number 2000
[DeviceA-bgp] network 1.1.1.0 255.0.0.0
[DeviceA-bgp] quit
3. Configure Device B
# Configure a BGP connection.
<DeviceB> system-view
[DeviceB] bgp 2000
[DeviceB-bgp] peer 168.1.1.1 as-number 1000
[DeviceB-bgp] peer 168.1.1.1 route-policy qppb import
[DeviceB-bgp] network 2.2.2.0 255.0.0.0
[DeviceB-bgp] quit
# Configure a routing policy.
[DeviceB] route-policy qppb permit node 0
[DeviceB-route-policy] apply qos-local-id 3
[DeviceB-route-policy] quit
# Configure a QoS policy.
[DeviceB] traffic classifier qppb
[DeviceB-classifier-qppb] if-match qos-local-id 3
[DeviceB-classifier-qppb] quit
[DeviceB] traffic behavior qppb
[DeviceB-behavior-qppb] car cir 512 green pass red discard
[DeviceB-behavior-qppb] quit
