I am not responding to all of the points raised in your message,
because you are still missing the fundamental problem that negative
replies from the LISP Mapping Service, which should be cached in the
ITR, can cause the table to be inflated to a size that is, literally,
ten times the number of possible positive mapping entries.  Once
again, read my original LISP mailing list post on this subject.

If you read the part in the MS draft that dictates negative replies
must not overlap any possible positive mappings, and consider how RIRs
are currently allocating IPv6 address space to networks, you should
easily realize how this part of the MS protocol needs additional
flexibility.  Quite simply, a 50k entry IPv6 table would indeed
consume 500k entries when negative entries are included.

The simple arithmetic is in my original post, months ago.
