Maintaining Ldp Sessions; Configuring Bfd For Mpls Ldp; Resetting Ldp Sessions; Managing And Optimizing Mpls Forwarding - HP 10500 SERIES Configuration Manual

To configure a DSCP value for outgoing LDP packets:
Step
1. Enter system view.
2. Enter MPLS LDP view.
3. Configure a DSCP value for
outgoing LDP packets.

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 bidirectional forwarding detection (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
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
normally. In this case, reset LDP sessions so the LDP peers will renegotiate parameters and establish new
sessions.
To reset LDP sessions, perform the following task in user view:
Task
Reset LDP sessions.

Managing and optimizing MPLS forwarding

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