This document describes how the control plane specified by BGP/MPLS IP VPNs [RFC4364] can be used to provide a network virtualization solution for end-systems that meets the requirements of large scale data-centers. It specifies how the control and forwarding functions of a Provide Edge (PE) device described in [RFC4364] can be separated such that the forwarding function can be implemented in end-systems themselves. The solution is applicable to any encapsulation that can deliver packets across an IP network as a tunneled IP datagram plus a 20-bit label.
