That’s not my point.

Whatever encapsulation or other system they are using, clearly they can’t do IPv6 for some reason because they outright refuse to even offer so much as a verification that IPv6 is on any sort of roadmap or is at all likely to be considered for deployment any time in the foreseeable future.

So, my point wasn’t that LISP is the only encapsulation that supports IPv6. Indeed, I didn’t even say that. What I said was that their apparent complete inability to do IPv6 makes it unlikely that they are using an IPv6-capable encapsulation system. Thus, it is unlikely they are using LISP. I only referenced LISP because it was specifically mentioned by the poster to whom I was responding.

Please try to avoid putting words in my mouth in the future.
