LISP Mobile Node
draft-ietf-lisp-mn-08
Abstract
This document describes how a lightweight version of LISP's ITR/ETR
functionality can be used to provide seamless mobility to a mobile
node. The LISP Mobile Node design described in this document uses
standard LISP functionality to provide scalable mobility for LISP
mobile nodes.
