2.14 Setting the DiffServ Mode Supported by MPLS VPNs

This section describes how to set the DiffServ mode supported by the MPLS L3VPN and the
MPLS L2VPN.

2.14.1 Establishing the Configuration Task

Applicable Environment
The DiffServ mode supported by the MPLS L3VPN includes three models: pipe, short pipe, and
uniform.

1. Run:
system-view
The system view is displayed.
2. Run:
mpls-qos ingress { use vpn-label-exp | trust upstream { ds-name | default
| none } }
The public tunnel label is mapped to the EXP field on the ingress PE.
Do as follows on the P:
1. Run:
system-view
The system view is displayed.
2. Run:
mpls-qos transit trust upstream { ds-name | default | none }
The public tunnel label is mapped to the EXP field on the P.
Do as follows on the egress PE:
1. Run:
system-view
The system view is displayed.
2. Run:
mpls-qos egress trust upstream { ds-name | default | none }
The public tunnel label is mapped to the EXP field on the egress PE.
This command must be run before the public tunnel is set up. If the command is run after
the public tunnel is set up, you must restart the MPLS LDP session; otherwise, the command
cannot take effect.
Pipe: The EXP value added to the MPLS label of the packets by the ingress PE is defined
by the user. If the EXP value is changed on the MPLS network, the new EXP value is valid
only on the MPLS network. The egress PE selects the PHB according to the EXP value of
the packet. When the packet leaves the MPLS network, the DSPC value becomes effective
again.
