Sounds like you should look at IS-IS protocol if you haven’t as that’s very close to the ip unnumbered routing you were talking about. Though isis is usually deployed with its on the interface of each device, it doesn’t have to be AFAIK.
I recently saw a post about Babel getting up unnumbered, and AFAIK OSPF and IS-IS have both had it for a while.
Implementations are spotty on support of unnumbered, there’s still quite a few, mostly older OSPF devices that require an IP interface to communicate with another device for OSPF.
I’ve been trying to get a functional IP unnumbered lab up and running but there’s a lot of unknown-unknowns for me still… At least when it comes to implementation.
Of course, a router ID is still a requirement, foreign devices still need a way to uniquely identify what device they’re talking to.
Maybe I should try the lab with IS-IS, but I know less about IS-IS than I do about OSPF at the moment. I should change that.
