Configuring the Limit Rate of MPLS TE Traffic

Configuring the Limit Rate of MPLS TE Traffic

This section describes how to configure the limit rate of MPLS TE traffic to limit TE tunnel traffic within the bandwidth range that is actually configured.

Usage Scenario

For a physical link of a TE tunnel, besides traffic on the TE tunnel, the physical link may bear MPLS traffic of other TE tunnels, MPLS traffic of other non-CR-LSPs, or even IP traffic simultaneously. To limit the TE tunnel traffic within a bandwidth range that is actually configured, set a limit rate for TE tunnel traffic.

After the configuration of the limit rate, TE traffic is limited to a bandwidth range that is actually configured. TE traffic with the bandwidth higher than the set bandwidth is dropped.

NOTE:
Before you configure the limit rate of MPLS TE traffic, run the mpls te bandwidth command on a tunnel interface. If this command is not run, the limit rate of MPLS TE traffic is unavailable.

Context

Before configuring the limit rate of MPLS TE traffic, configure a static CR-LSP or an RSVP-TE tunnel.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface tunnel tunnel-number

    The tunnel interface view is displayed.

  3. Run:

    mpls te bandwidth

    The bandwidth constraint of the MPLS TE tunnel is configured.

  4. Run:

    mpls te lsp-tp outbound

    The TE traffic policing is configured.

  5. Run:

    commit

    The configuration is committed.

Checking the Configurations

  • Run the display current-configuration interface Tunnel tunnel-number command. The command output shows that the rate limit function has been enabled.
