The point about using EID space prefixes as an indication of which sites have been upgraded is that it need not interfere with existing deployments nor require that existing deployments ever transition.
Let's say the EID space is IPv6, and we say that some portion of that space (e.g., 2001::/16) stays as legacy and all the rest goes as the objective deployment. Then, a site that is using a non-2001::/16 is unambiguously known to be upgraded. I think this eases the transition for either six/one or LISP?
