Technical Summary

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
describes a specification whereby a single CPE can interwork with
all of the standardized and proposed approaches to providing
encapsulated IPv4 in IPv6 services.

Working Group Summary

   This document was discussed in depth and well-reviewed.

There are currently no known implementations, however an operator/vendor 
has one scheduled for development later this year.

Personnel

   Yong Cui, is the Document Shepherd.
   Terry Manderson is the Responsible AD.


IANA Note

  This document needs IANA to assign a new DHCPv6 option code
OPTION_V6_S46_PRIORITY.
