LDP Signaling and Services
When LDP is enabled, targeted sessions can be established to create remote adjacencies with
nodes that are not directly connected. When service distribution paths (SDPs) are configured,
extended discovery mechanisms enable LDP to send periodic targeted hello messages to the SDP’s
far-end point. The exchange of LDP hellos trigger session establishment. The SDP’s signaling
default enables tldp. The service SDP uses the targeted-session parameters configured in the
config>router>ldp>targeted-session
context.
The 7210 SAS M supports only Targeted LDP (TLDP).
The following example displays the command syntax usage to configure enable LDP on an MPLS
SDP:
CLI Syntax: config>service>sdp#
signaling {off|tldp}
The following displays an example of an SDP configuration showing the signaling default
tldp
enabled.
