Configuring LDP Discovery Over a Link
Perform this task to configure LDP discovery over a link.
There is no need to enable LDP globally.
Note
Before You Begin
A stable router ID is required at either end of the link to ensure the link discovery (and session setup) is
successful. If you do not assign a router ID to the routers, the system will default to the global router ID.
Default router IDs are subject to change and may cause an unstable discovery.
