The experimental IPv6 Destination Option is called the VPN Service Option. One purpose of this experiment is to demonstrate that the VPN Service Option can be deployed in a production network. Another purpose is to demonstrate that the security measures described in this document are sufficient to protect a VPN. Finally, this document encourages replication of the experiment.
