Configuring an MPLS LDP Tunnel

Procedure

1. Run system-view

   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 mpls

   MPLS is enabled globally, and the MPLS view is displayed.

4. Run mpls ldp

   MPLS LDP is enabled globally, and the MPLS-LDP view is displayed.

5. Run quit

   Return to the system view.

6. Run interface interface-type interface-number

   The view of the interface on which an LDP session is to be established is displayed.

7. Run mpls

   MPLS is enabled on an interface.

8. Run mpls ldp

   MPLS LDP is enabled on an interface.

   

   Disabling MPLS LDP from an interface leads to interruptions of all LDP sessions on the interface and deletions of all LSPs established over these LDP sessions.

9. Run commit

   The configuration is committed.
