Enabling MPLS TE and RSVP-TE

Enabling MPLS TE and RSVP-TE

MPLS TE and RSVP-TE must be enabled on each LSR in an MPLS domain before TE functions are configured.


  • If MPLS TE is disabled in the MPLS view, MPLS TE enabled in the interface view is also disabled. As a result, all CR-LSPs configured on this interface go Down, and all configurations associated with these CR-LSPs are deleted.

  • If MPLS TE is disabled in the interface view, all CR-LSPs on the interface go Down.

  • If RSVP-TE is disabled on an LSR, RSVP-TE is also disabled on all interfaces on this LSR.


  1. Run:


    The system view is displayed.

  2. Run:

    mpls lsr-id lsr-id

    The LSR ID of the local node is configured.

    When configuring an LSR ID, note the following:
    • Configuring an LSR ID is the prerequisite of all MPLS configurations.

    • An LSR ID must be manually configured because no default LSR ID is available.

    • Use the IP address of a loopback interface on an LSR as an LSR ID.


      The undo mpls command deletes all MPLS configurations, including the established LDP sessions and LSPs.

  3. Run:


    The MPLS view is displayed.

  4. Run:

    mpls te

    MPLS TE is enabled globally.

  5. Run:

    mpls rsvp-te

    The view of the interface on which the MPLS TE tunnel is established is displayed.

  8. Run:


    MPLS is enabled on an interface.

  9. Run:

    mpls te

    MPLS TE is enabled on the interface.
