ONFIGURATION

Perform the following compulsory tasks in configuring LDP:

■

Enable LDP

■

Enable LDP on Interface

Perform the following optional tasks in configuring LDP:

■

Configure LDP extended discovery mode

■

Configure the label of the penultimate hop at the egress

■

Configure session parameters

■

Configure LDP loop detection control

■

Configuring LDP authentication mode

To configure LDP, first enable LDP.

Perform the following in the System View.

By default, LDP is disabled.

To enable MPLS on an interface, it is necessary to enable the LDP on an interface in 
the interface view. Then the interface is capable of establishing LDP session and 
forwarding labeled packet. 

Disabling LDP function will delete LDP peer, delete LSP tunnel, close TCP 
connection, interrupt peer LDP session, stop sending HELLO packets, and stop 
label packet forwarding. 

Perform the following in the Interface View. 

By default, the interface MPLS function is disabled.

It is to create extended discovery mode, to set up sessions with peers not directly 
connected to the link.
