        Minimum Requirements for IPv6-only Customer Edge Routers
                   draft-palet-v6ops-rfc7084-bis2-00

Abstract

   This document specifies minimum requirements for an IPv6-only
   Customer Edge (CE) router.  Specifically, the current version of this
   document focuses on the basic provisioning of an IPv6-only CE router
   and the provisioning of IPv6 hosts attached to it.  Neither the
   provisioning of IPv4 nor downstream routers are in the scope of this
   document.  The document obsoletes RFC 7084.

1.  Introduction

   This document defines minimum IPv6 features for a very basic
   residential or small- office router, referred to as an "IPv6-only CE
   router", in order to establish an industry baseline for features to
   be implemented on such a router.  This is, as well, the router to be
   used in remote locations where IPv6-only LANs/devices are used to
   connect sensors, displays, etc.

   These routers don't support IPv4, neither functionalities for
   provisioning downstream routers.

   This document specifies how an IPv6-only CE router automatically
   provisions its WAN interface, acquires address space for provisioning
   of its LAN interfaces, and fetches other configuration information
   from the service provider network.  Automatic provisioning of more
   complex topology than a single router with multiple LAN interfaces is
   out of scope for this document.

   This document doesn't cover the specific details of each possible
   access technology.  For example, if the CE is supporting built-in or
   external 3GPP/LTE interfaces, [RFC7849] is a relevant reference.  See
   [RFC4779] for a discussion of options available for deploying IPv6 in
