Cisco Systems, Inc. April 2011 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.

Typically, these routers 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 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. See [RFC4779] for a discussion of options available for deploying IPv6 in service provider access networks. Singh, et al. Informational [Page 2] RFC 6204 IPv6 CE Router Requirements April 2011 1.1.
