  3. Purpose of the draft • Define Data plane requirements for Data Center Network Virtualization over L3 • Virtual Access Point (VAP) Identification • L2 & L3 Virtual Network Instance (VNI) services and TTL handling • Integrated routing and bridging optional • NVo3 overlay header following tunneling headder • Virtual Network (VN) context Identification(VNID) - globally unique in context of an administrative domain or locally significant identifier • Service QoS identification • Network Virtual Edge (NVE) tunnelling functions • IPv4&IPv6 encapsulation (MUST) & MPLS encapsulation (MAY) • Entropy to support effective load-balancing over LAG and ECMP • DiffServ & ECN marking • BUM handling – ingress replication support MUST • External connectivity via GWs and GW types • Path optimality • Path MTU handling • OAM support

  4. VNI Types • L2 VNI • Emulated Ethernet multipoint service • MAC address learning via • Data-plane learning • Control/Management plane MAC address population • L3 VNI • Virtualized IP routing & forwarding • Integrated Routing and Bridging on NVE

  5. Next Steps • Make entropy requirement more generic • e.g. “the encapsulation MUST result in sufficient entropy to exercise all paths through several LAG/ECMP hops” • Expand on L3 multicast group support and dual-homing • Solicit further comments from the WG
