Usage guidelines

Before you enable LDP on an interface, use the mpls ldp command in system view to enable LDP globally.

Disabling LDP on an interface terminates all LDP sessions on the interface, and removes all LSPs

established through the sessions.

If the interface is bound to a VPN instance, you must also use the vpn-instance command to enable LDP

for the VPN instance.

An up interface enabled with LDP and MPLS sends Link Hellos for neighbor discovery.

An up MPLS TE tunnel interface enabled with LDP sends Targeted Hellos to the tunnel destination and

establishes a session to the tunnel peer. Establishing an LDP session is the prerequisite of implementing

LDP over MPLS TE.
