Unified IPv4-in-IPv6 Softwire Customer Premises Equipment : A DHCPv6-Based Prioritization Mechanism
RFC 8026, “Unified IPv4-in-IPv6 Softwire Customer Premises Equipment : A DHCPv6-Based Prioritization Mechanism”, is a Proposed Standard document published in November 2016 by M. Boucadair, I. Farrer. The canonical text is published by the RFC Editor.
Abstract
In IPv6-only provider networks, transporting IPv4 packets encapsulated in IPv6 is a common solution to the problem of IPv4 service continuity. A number of differing functional approaches have been developed for this, each having their own specific characteristics. As these approaches share a similar functional architecture and use the same data plane mechanisms, this memo specifies a DHCPv6 option, whereby a single instance of Customer Premises Equipment (CPE) can interwork with all of the standardized and proposed approaches to providing encapsulated IPv4-in-IPv6 services by providing a prioritization mechanism.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
