  An Architectural Introduction to the Locator/ID Separation Protocol
                                 (LISP)

Abstract

   This document describes the architecture of the Locator/ID Separation
   Protocol (LISP), making it easier to read the rest of the LISP
   specifications and providing a basis for discussion about the details
   of the LISP protocols.  This document is used for introductory
   purposes, more details can be found in RFC6830, the protocol
   specification.
