Mpls Qos Configuration Example - HP FlexNetwork 6600 Configuration Manual

MPLS QoS configuration example

Network requirements
As shown in
•
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.
