The new IPv6 Destination Option is called the VPN Service Option. One purpose of this experiment is to demonstrate that the VPN Service Option can be implemented and deployed in a production network. Another purpose is to demonstrate that the security considerations, described in this document, have been sufficiently addressed. Finally, this document encourages replication of the experiment.
