         LISP L2/L3 EID Mobility Using a Unified Control Plane
                    draft-ietf-lisp-eid-mobility-03

Abstract

   The LISP control plane offers the flexibility to support multiple
   overlay flavors simultaneously.  This document specifies how LISP can
   be used to provide control-plane support to deploy a unified L2 and
   L3 overlay solution for End-point Identifier (EID) mobility, as well
   as analyzing possible deployment options and models.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at https://datatracker.ietf.org/drafts/current/.
