Abstract

   This document describes the scenarios for IPv6 deployment within
   enterprise networks.  It defines a small set of basic enterprise
   scenarios and includes pertinent questions to allow enterprise
   administrators to further refine their deployment scenarios.
   Enterprise deployment requirements are discussed in terms of
   coexistence with IPv4 nodes, networks and applications, and in terms
   of basic network infrastructure requirements for IPv6 deployment.
   The scenarios and requirements described in this document will be the
   basis for further analysis to determine what coexistence techniques
   and mechanisms are needed for enterprise IPv6 deployment.  The
   results of that analysis will be published in a separate document.

1.  Introduction

   This document describes the scenarios for IPv6 deployment within
   enterprise networks.  It defines a small set of basic enterprise
   scenarios and includes pertinent questions to allow enterprise
   administrators to further refine their deployment scenarios.
   Enterprise deployment requirements are discussed in terms of
   coexistence with IPv4 nodes, networks and applications, and in terms
   of basic network infrastructure requirements for IPv6 deployment.
   The scenarios and requirements described in this document will be the
   basis for further analysis to determine what coexistence techniques
   and mechanisms are needed for enterprise IPv6 deployment.  The
   results of that analysis will be published in a separate document.

   The audience for this document is the enterprise network team
   considering deployment of IPv6.  The document will be useful for
   enterprise teams that will have to determine the IPv6 transition
   strategy for their enterprise.  It is expected those teams include
   members from management, network operations, and engineering.  The
   scenarios presented provide an example set of cases the enterprise
   can use to build an IPv6 network scenario.

   To frame the discussion, this document will describe a set of
   scenarios each with a network infrastructure.  It is impossible to
   define every possible enterprise scenario that will apply to IPv6
   adoption and transition.

   Each enterprise will select the transition that best supports their
   business requirements.  Any attempt to define a default or one-size-
   fits-all transition scenario, simply will not work.  This document
   does not try to depict the drivers for adoption of IPv6 by an
   enterprise.

   While it is difficult to quantify all the scenarios for an enterprise
   network team to plan for IPv6, it is possible to depict a set of
   abstract scenarios that will assist with planning.  This document
