This is an introduction about 6RD, a protocol to transport IPv6 in IPv4 invented by Remi Despres. It is the protocol for SPs who want to provide access to their customers over an IPv4 Internal Backbone.
It is actually 6to4 protocol customized for Service Providers with a configurable prefix.
It has been deployed in 2007 by Free, a French SP and has proven its scalability and its reliability.
It is supported by CISCO in IOS and in other devices like ASR1K for the BR and in more and more cheap CPE for access as well as Linux.
For a full overview of all the principle Transition Protocols, please refer to this blog:
