Basic Requirements for IPv6 Customer Edge Routers
Abstract
This document specifies requirements for an IPv6 Customer Edge (CE)
router. Specifically, the current version of this document focuses
on the basic provisioning of an IPv6 CE router and the provisioning
of IPv6 hosts attached to it. The document also covers IP transition
technologies. Two transition technologies in RFC 5969's IPv6 Rapid
Deployment on IPv4 Infrastructures (6rd) and RFC 6333's Dual-Stack
Lite (DS-Lite) are covered in the document. The document obsoletes
RFC 6204.

RFC 7084 IPv6 CE Router Requirements November 2013
1. Introduction
This document defines basic IPv6 features for a residential or small-
office router, referred to as an "IPv6 CE router", in order to
establish an industry baseline for features to be implemented on such
a router.
These routers typically also support IPv4.
Mixed environments of dual-stack hosts and IPv6-only hosts (behind
the CE router) can be more complex if the IPv6-only devices are using
a translator to access IPv4 servers [RFC6144]. Support for such
mixed environments is not in scope of this document.
This document specifies how an IPv6 CE router automatically
provisions its WAN interface, acquires address space for provisioning
