Usage guidelines
Before you enable LDP for 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 with 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 with the tunnel peer.
Examples

<Sysname> system-view
[Sysname] mpls ldp
[Sysname-ldp] quit
[Sysname] interface vlan-interface 2
