The problem I personally have is that I don't feel comfortable in making either of those assumptions. In fact, one might argue that making both of these assumptions is what has gotten us into trouble in the first place.

I think one must argue that either this is the case or is not the case, but not leave this sort of thought just dangling. For my part, I'll argue that no such assumptions were made, but that we simply did what we knew how to do, and knew of no better approach.

Whether or not the assumptions were explicitly made in the past isn't really relevant and I do not mean to imply any criticism -- I would agree we did what we knew how to do. However, we know more now so we should take that information into account.

A *fundamental* change between today and the world we perceive with LISP is how we manage different types of state. Today everything is lumped together in operational state. LISP separates that state into two buckets and treats them quite differently.

Yes. The issue (at least for me) is how to propagate the mapping info since we're moving the scaling thrash problem from the FIB to the map. Pushing around the whole mapping table seems to me to have the potential of simply recreating the problem 'later'.
