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
