Configuring the LDP Remote Peer

Procedure

1. Run system-view

   The system view is displayed.

2. Run mpls ldp remote-peer remote-peer-name

   A remote MPLS LDP peer is created, and the remote MPLS LDP peer view is displayed.

3. (Optional) Run description description-value

   The description of a remote peer is configured.

4. Run remote-ip ip-address

   The IP address is assigned to the remote MPLS LDP peer.

   The remote MPLS LDP peer must use the LSR ID as the IP address.

   

   • The IP address of a remote LDP peer must be the LSR ID of the remote LDP peer. If an LDP LSR ID is different from an MPLS LSR ID, the LDP LSR ID is used.

   • Modifying or deleting a configured IP address of a remote peer also deletes the remote LDP session.

5. (Optional) Perform either of the following operations to prevent label distribution to remote LDP peers:

   • Run remote-ip ip-address pwe3

     The local LSR is prevented from distributing labels to a specified remote MPLS LDP peer.

   • To prevent label distribution to all remote LDP peers, perform the following sub-steps:

     • (Optional) Run clear remote-ip pwe3

       The explicit configuration of enabling or disabling the ability to distribute labels to a specified remote LDP peer is deleted.

       If an explicit configuration has been performed to allow a device to distribute labels to a specified remote LDP peer, to delete the configuration, you can perform this step.

     • Run quit

       Return to the system view.

     • Run mpls ldp

       The MPLS-LDP view is displayed.

     • Run remote-peer pwe3

     The local LSR is disabled from distributing labels to all remote MPLS LDP peers.

   

   When, run the preceding commands to prohibit labels from being distributed to the remote MPLS LDP peers, which helps efficiently use system resources. When TE services are transmitted over a backbone network in the LDP over TE scenario, do not perform this configuration.

6. Run commit

   The configuration is committed.
