Configuring LDP Discovery for Active Targeted Hellos
Perform this task to configure LDP discovery for active targeted hellos.
Note The active side for targeted hellos initiates the unicast hello toward a specific destination.
Before You Begin
These prerequisites are required to configure LDP discovery for active targeted hellos:
• Stable router ID is required at either end of the targeted session. If you do not assign a router ID to the
• One or more MPLS Traffic Engineering tunnels are established between non-directly connected LSRs.
SUMMARY STEPS
1. configure
2. mpls ldp
3. router-id ip-address
4. interface type interface-path-id
5. Use the commit or end command.

routers, the system will default to the global router ID. Please note that default router IDs are subject to
change and may cause an unstable discovery.
Purpose
(Optional)
Displays the status of the LDP discovery process. This command, without
an interface filter, generates a list of interfaces over which the LDP
discovery process is running. The output information contains the state
of the link (xmt/rcv hellos), local LDP identifier, the discovered peer's
LDP identifier, and holdtime values.
