 Locator/ID Separation Protocol (LISP) Endpoint Identifier (EID) Block

Abstract

   This document directs IANA to allocate a /32 IPv6 prefix for use with
   the Locator/ID Separation Protocol (LISP).  The prefix will be used
   for local intra-domain routing and global endpoint identification, by
   sites deploying LISP as Endpoint Identifier (EID) addressing space.

RFC 7954                     LISP EID Block               September 2016

1.  Introduction

   This document directs the IANA to allocate a /32 IPv6 prefix for use
   with the Locator/ID Separation Protocol (LISP [RFC6830]), LISP Map-
   Server ([RFC6833]), LISP Alternative Topology (LISP+ALT [RFC6836])
   (or other) mapping systems, and LISP Interworking ([RFC6832]).

   This block will be used as global Endpoint Identifier (EID) space.

2.  Definition of Terms

   The present document does not introduce any new terms with respect to
   the set of LISP Specifications ([RFC6830], [RFC6831], [RFC6832],
   [RFC6833], [RFC6834], [RFC6835], [RFC6836], [RFC6837]), but it
   assumes that the reader is familiar with the LISP terminology.
   [LISP-INTRO] provides an introduction to the LISP technology,
   including its terminology.

3.  Rationale and Intent

   Discussion within the LISP working group led to the identification of
   several scenarios in which the existence of a LISP-specific address
   block brings technical benefits.  The most relevant scenarios are
   described below:

   Early LISP destination detection:  With the current specifications,
