Enabling Global MPLS LDP

Enabling Global MPLS LDP


You can perform other MPLS LDP configurations only after enabling global MPLS LDP.

Perform the following steps on each node in an MPLS domain.


  1. Run system-view

    The system view is displayed.

  2. Run mpls ldp

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

    By default, LDP is not enabled globally.

  3. (Optional) Run lsr-id lsr-id

    The LSR ID is set for an LDP instance.

    By default, the LSR ID of the LDP instance is the LSR ID of the local node. It is recommended that the default value be used.

    In certain networking where VPN instances are used, such as BGP/MPLS IP VPN networking, if the VPN address and the LSR ID overlap, you need to configure LSR IDs for LDP instances to ensure that TCP connections can be correctly set up.
