Configuration Guide - MPLS

S7700 and S9700 V200R011C10

This document describes MPLS configurations supported by the switch, including the principle and configuration procedures of static LSPs, MPLS LDP, MPLS TE, MPLS QoS, MPLS OAM, Seamless MPLS, and MPLS common features, and provides configuration examples.

(Optional) Configuring Link Bandwidth

(Optional) Configuring Link Bandwidth


When a non-Huawei device as the ingress node of an MPLS TE tunnel initiates a request for setting up a CR-LSP with bandwidth constraints, configure link bandwidth on the connected Huawei device for negotiation so that the CR-LSP can be set up and network resources are used efficiently.


The configured bandwidth takes effect only during tunnel establishment and protocol negotiation, and does not limits the bandwidth for traffic forwarding. (The X1E series, cards do not have this restriction.)

Perform the following configurations on each node of the MPLS TE tunnel.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The MPLS-TE-enabled interface view is displayed.

  3. (Optional) On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

  4. Run mpls te bandwidth max-reservable-bandwidth bw-value

    The maximum available bandwidth of the link is configured.

    By default, the maximum reservable bandwidth of a link is 0 bit/s. The bandwidth allocated to a static CR-LSP built over a link is certainly higher than 0 bit/s. If the maximum reservable bandwidth of the link is not configured, the static CR-LSP cannot be set up due to insufficient bandwidth.

  5. Run mpls te bandwidth { bc0 bc0-bw-value | bc1 bc1-bw-value } *

    The BC bandwidth of the link is configured.

    • The maximum reservable bandwidth of a link cannot be greater than the actual bandwidth of the link. A maximum of 80% of the actual bandwidth of the link is recommended for the maximum reservable bandwidth of the link.
    • Neither the BC0 bandwidth nor the BC1 bandwidth can be greater than the maximum reservable bandwidth of the link.
