                  LISP Canonical Address Format (LCAF)

Abstract

   This document defines a canonical address format encoding used in
   Locator/ID Separation Protocol (LISP) control messages and in the
   encoding of lookup keys for the LISP Mapping Database System.

Status of This Memo

   This document is not an Internet Standards Track specification; it is
   published for examination, experimental implementation, and
   evaluation.

   This document defines an Experimental Protocol for the Internet
   community.  This document is a product of the Internet Engineering
   Task Force (IETF).  It represents the consensus of the IETF
   community.  It has received public review and has been approved for
   publication by the Internet Engineering Steering Group (IESG).  Not
   all documents approved by the IESG are a candidate for any level of
   Internet Standard; see Section 2 of RFC 7841.
