EVN6: Mapping of Ethernet Virtual Network to IPv6 Underlay for Transmission

This document describes a mechanism of mapping of Ethernet Virtual Network to IPv6 Underlay for transmission. Unlike the existing methods, this approach places the Ethernet frames to be transmitted directly in the payload of IPv6 packets, i.e., L2 over IPv6, and uses stateless mapping to generate IPv6 source and destination addresses from the host's MAC addresses, the Ethernet Virtual Network identifier and site prefixes. The IPv6 packets generated in this way carry Ethernet frames and are routed to the destination site across the public IPv6 network.
