I'm looking for a simple way to allow a router discover communication devices over a LAN. I've heard a bit about DLEP and LLDP, but aside from understanding that LLDP is older, and DLEP has only recently achieved an RFC status, I couldn't find much more.
What I'm interested to know is:
- What is the adoption status of any of the two? Is any of them widely used?
- Does one of them has a significant advantage over the other, a "killer feature" that makes it much more relevant and useful?
