  Attribute-Value Pairs for Provisioning Customer Equipment Supporting
                 IPv4-Over-IPv6 Transitional Solutions

Abstract

   During the transition from IPv4 to IPv6, customer equipment may have
   to support one of the various transition methods that have been
   defined for carrying IPv4 packets over IPv6.  This document
   enumerates the information that needs to be provisioned on a customer
   edge router to support a list of transition techniques based on
   tunneling IPv4 in IPv6, with a view to defining reusable components
   for a reasonable transition path between these techniques.  To the
   extent that the provisioning is done dynamically, Authentication,
   Authorization, and Accounting (AAA) support is needed to provide the
   information to the network server responsible for passing the
   information to the customer equipment.  This document specifies
   Diameter (RFC 6733) Attribute-Value Pairs (AVPs) to be used for that
   purpose.
