         LISP Control Plane for Network Virtualization Overlays
                      draft-maino-nvo3-lisp-cp-03

Abstract

   The purpose of this draft is to analyze the mapping between the
   Network Virtualization over L3 (NVO3) requirements and the
   capabilities of the Locator/ID Separation Protocol (LISP) control
   plane.  This information is provided as input to the NVO3 analysis of
   the suitability of existing IETF protocols to the NVO3 requirements.

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

   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
