Maintaining LDP sessions

This section describes how to detect communication failures between remote LDP peers and reset
LDP sessions.

Configuring BFD for MPLS LDP

Use BFD to help MPLS promptly detect a neighbor failure or link failure between two remote LDP
peers. BFD can help MPLS LDP detect communication failures only between remote LDP peers. For
configuration examples, see "Configuring VPLS." For more information about BFD, see High
Availability Configuration Guide.
To configure BFD for MPLS LDP:
Step
1. Enter system view.
2. Enter MPLS LDP remote
peer view.
3. Enable BFD for MPLS
LDP.

Resetting LDP sessions

If you change LDP session parameters when some LDP sessions are up, the LDP sessions cannot
function correctly. In this case, reset LDP sessions so the LDP peers will renegotiate parameters and
establish new sessions.
To reset LDP sessions:
Task
Reset LDP sessions.

Managing and optimizing MPLS forwarding

Perform the tasks in this section to manage and optimize MPLS forwarding for higher performance.
