"Runs in top of UDP"... "Is not UDP"...

If it has protocol set to 17 it is UDP.

Lisp is actually very much about multihoming... In fact that was one of the
key reasons it got started. It actually could make multihoming and mobility
very much simpler at the applications if it were used.

It is a bit complex though... At least for normal ivp4/6 routing minded
folk.
