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 HUAWEI NetEngine 8000 F Series Router Configuration Guide - MPLS.
Do as follows on MPLS LSP or MPLS TE penultimate hop:
Procedure
- Run system-view
The system view is displayed.
- Run mpls
The MPLS view is displayed.
- Run mpls lsp exp-mode { pipe | uniform }
The global MPLS DiffServ 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.
- Run commit
The configuration is committed.
