Re: [MEXT] LISP as a solution for some part of the DMM requirement

[<[e-mail]>]

I agree with Romain's comment.
The scope of DMM within the context of the MEXT WG is to reuse Mobile IPv6
protocols, extensions and elements to address the concerns of the base
Mobile IP model. 

Mobility using LISP may be a good solution in itself. I have no idea or
opinion about such a solution at the present time.

I believe that we can address the DMM requirements with a few extensions
to MIP6 signaling and guidelines for deployment. Expanding the scope of
DMM beyond the base MIP6 protocol would be taking us down a path with no
visible end.
