Configuring the Mapping of the Precedence in the Public MPLS Tunnel Label

Configuring the Mapping of the Precedence in the Public MPLS Tunnel Label

To implement the QoS function on an MPLS network, the switch needs to determine the packet precedence according to the tunnel label on the MPLS public network. Therefore, it is necessary to map the tunnel label to the EXP field.

Pre-configuration Tasks

Before configuring the mapping of the precedence in the tunnel label, complete the following tasks:

  • Configure a local LDP session. For details, see Configuring Basic Functions of MPLS LDP.

  • Create a DiffServ domain. For details, see Priority Mapping Configuration in the S7700 and S9700 V200R013C00 Configuration Guide - QoS.

Configuration Procedure

Configure the mapping of the precedence in the tunnel label in the following sequence.
