Verifying the Local LDP Session Configuration

Verifying the Local LDP Session Configuration

After configuring a local MPLS LDP session, you can view information about interfaces with MPLS and MPLS LDP enabled, the LDP protocol, LDP session status, LDP adjacencies, and peers of the LDP session.

Prerequisites

The local MPLS LDP session has been established.

Procedure

  • Run the display mpls ldp [ all ] [verbose ] command to check LDP information.
  • Run the display mpls ldp interface [ interface-type interface-number | verbose | all ] command to check information about an LDP-enabled interface.
  • Run the display mpls ldp session [ verbose | peer-id | all ] command to check the status of an LDP session.
  • Run the display mpls ldp adjacency [ interface interface-type interface-number | remote ] [ peer peer-id ] [ verbose ] command to check information about LDP adjacencies.
  • Run the display mpls ldp peer [ verbose | peer-id | all ] command to check the peers of an LDP session.
  • Run the display mpls interface [ interface-type interface-number ] [ verbose ] command to check information about an MPLS-enabled interface.

Example

Run the display mpls ldp command to view global information about LDP, including timers.
