ONFIGURATION

By default, LDP is disabled.

To make the VLAN interface support LDP, you must enable LDP function on the 
interface in VLAN interface mode. After enabling the LDP function, the interface 
then sets up session. It begins to set up LSP if in topology-driven mode,.

Disabling LDP function on interface causes the break of all LDP session in VLAN 
interface, and all the LSP based on those sessions are deleted. So you must use this 
command with cautiously.

Perform the following configuration in the interface view.

By default, the interface LDP function is disabled.

The Remote-peer configuration is mainly used for extended discovery mode so 
that this LSR can establish sessions with LSRs that are not directly connected with 
it at the link layer.

Perform the following configuration in the system view.

There is no default remote-peer.

You can specify the address of any LDP-enabled interface on the Remote-peer or 
the address of the Loopback interface on the LSR that has advertised the route as 
the address of the Remote-peer.

Perform the following configuration in the Remote-peer view.
