MPLS QoS configuration example

Network requirements

As shown in Figure 42:

• Both CE 1 and CE 2 belong to VPN 1.

• The bandwidth of the link between PE 1 and P is 2 M.

• The bandwidth of the link between PE 2 and P is 2 M.

Provide differentiated QoS services for flows with different precedence values in VPN 1.

The configuration in this example involves the following parts:

First, configure MPLS VPN on CE 1, PE 1, P, PE 2, and CE 2 as follows:

• Run OSPF between PE 1 and P, and between PE 2 and P.

• Form a MP-EBGP neighborship between PE and CE.

• Form a MP-IBGP neighborship between PE and PE.

Second, configure MPLS QoS on PE 1 and P as follows:

• Configure a QoS policy on the incoming interface GigabitEthernet 1/0/1 on PE 1 and set the EXP

field value for an MPLS packet according to the DSCP attribute of the MPLS packets.

• On the device P, classify traffic on the basis of the EXP field and configure flow-based CBQ:

guarantee 10% of the bandwidth for traffic with an EXP value of 1, guarantee 20% of the bandwidth

for traffic with an EXP value of 2, guarantee 30% of the bandwidth for traffic with an EXP value of

3, and guarantee a low delay and 40% of the bandwidth for traffic with an EXP value of 4.

For the MPLS VPN configuration, see MPLS Configuration Guide. This section introduces only the MPLS

QoS configuration.
