Yes, LISP is good for you! :-)

There is a huge difference between using LISP and 6to4 that you're not =
considering here.=20
6to4 was specifically invented to solve the particular problem of =
IPv6/IPv4 transition. That is its sole purpose for existence.=20
LISP was not invented to solve this problem - it was invented to address =
a much broader set of problems that neither IPv4 or IPv6 address (e.g. =
overloaded address semantics, multi-homing simplicity, IP mobility, and =
address portability).=20
The fact that LISP does help in IPv6 Transition solutions (due to its =
inherent AF agnostic design), is compelling. As you say, real edge 2 =
edge is the goal - and LISP helps here, regardless of the AF. (you'll =
will still want to do multi-homing in IPv6, and ingress TE, and =
mobility, etc.).=20
So it won't have the the same fate as 6to4.
Kind regards,
