Transporting IPv4 packets encapsulated in IPv6 is a common solution to the problem of IPv4 service continuity over IPv6-only provider networks. 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 describes a specification whereby a single CPE can interwork with all of the standardized and proposed approaches to providing encapsulated IPv4 in IPv6 services.
