Configuring LDP Discovery for Active Targeted Hellos
Perform this task to configure LDP discovery for active targeted hellos.
The active side for targeted hellos initiates the unicast hello toward a specific destination.Note
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
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.
•
One or more MPLS Traffic Engineering tunnels are established between non-directly connected LSRs.
