Configuring the Uniform/Pipe Mode for the MPLS Penultimate Hop

Configuring the Uniform/Pipe Mode for the MPLS Penultimate Hop

This section describes the process of configuring the Uniform/Pipe mode for the MPLS penultimate hop.

Pre-configuration Tasks

Before configuring the Uniform/Pipe model for the MPLS penultimate node, complete the following tasks:

  • Configuring physical parameters and link attributes of related interfaces to ensure normal operation of the interfaces

  • Configuring a Uniform/Pipe mode for the MPLS TE penultimate hop, which needs the configuration of an MPLS TE tunnel. see "MPLS TE Configuration" in the HUAWEI NetEngine40E Universal Service Router Configuration Guide - MPLS.


Do as follows on MPLS LSP or MPLS TE penultimate hop:


  1. Run:


    The system view is displayed.

  2. Run:


    The MPLS view is displayed.

  3. Run:

    mpls lsp exp-mode { pipe | uniform }

    The global MPLS Diff-Serv mode is set.

    • The configured mode by running this command take effect only on new LSPs. The reset mpls ldp command can be used to re-establish the original LSPs. Then, the configured mode can take effect on the re-established LSPs.
    • The command is run only on the penultimate hop to control the copy of the EXP value of an outer label to the EXP value of an inner label.

  4. Run:


    The configuration is committed.
