MPLS LSP tunnels with LDP - Cisco Learning Network
LDP is not mandatoey for RSVP-TE tunnel. For RSVP-TE tunnel RSVP is mandatory :-) But LDP is mandatory let's say for "usual" MPLS operation. So, the topmost label is LDP, the next one …
Making sense of MP-BGP, LDP and IGP in an MPLS SP domain
- LDP is required to automatically signal the LSP's based on the best next-hops calculated by the underlying IGP by advertising labels (based on next hops) to directly connected LDP …

Why is LDP neighbor not to loopback IP - Cisco Learning Network
Doug, Routers select their LDP ID very similar to how they do it for OSPF. Highest loopback address first, then highest physical address. You need to bounce your LDP process to change …
