3. Enable QPPB on
the interface.
bgp-policy { destination | source }
{ ip-prec-map | ip-qos-map } *
The command applies to only incoming
traffic.
Configuring a QoS policy
The classes in the QoS policy use the IP precedence and QoS-local ID set by the routing policy as match
criteria.
Applying the QoS policy to an interface

Command Remarks
1. Enter system view.

2. Enter interface view.

N/A
3. Apply the specified
policy to the
interface.
qos apply policy policy-name
{ inbound | outbound }
On some cards, QoS policies can be
applied but cannot take effect due to
limited system resources. In this case, you
can adjust related parameters (for
example, reducing the number of queues)
according to system prompt and then
apply a QoS policy again.
QPPB configuration examples
QPPB configuration example in an IPv4 network
Network requirements
As shown in Figure 35, all routers run BGP.
Configure QPPB, so that Router B can receive routes, set IP precedence and QoS-local IDs according to
the routing policy, and use the QoS policy to limit the traffic rate to 512 kbps.
