           Basic Requirements for IPv6 Customer Edge Routers
                      draft-ietf-v6ops-6204bis-05

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 6rd and RFC
   6333's DS-Lite. are covered in the document.  The document obsoletes
   RFC 6204, if approved.
