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.
