                   draft-ietf-bess-evpn-geneve-01.txt

Abstract

   This document describes how Ethernet VPN (EVPN) control plane can be
   used with Network Virtualization Overlay over Layer 3 (NVO3) Generic
   Network Virtualization Encapsulation (Geneve) encapsulation for NVO3
   solutions.

   EVPN control plane can also be used by a Network Virtualization
   Endpoints (NVEs) to express Geneve tunnel option TLV(s)supported in
   transmission and/or reception of Geneve encapsulated data packets.

1.  Introduction

   The Network Virtualization over Layer 3 (NVO3) solutions for network
   virtualization in data center (DC) environment are based on an IP-
   based underlay.  An NVO3 solution provides layer 2 and/or layer 3
   overlay services for virtual networks enabling multi-tenancy and
   workload mobility.  The NVO3 working group have been working on
   different dataplane encapsulations.  The Generic Network
   Virtualizationi Encapsulation [I-D.ietf-nvo3-geneve] have been
   recently recommended to be the proposed standard for network
   virtualization overlay encapsulation.

   This document describes how the EVPN control plane can signal Geneve
   encapsulation type in the BGP Tunnel Encapsulation Extended Community
   defined in [I-D.ietf-idr-tunnel-encaps].  In addition, this document
   defines how to communicate the Geneve tunnel option types in a new
   BGP Tunnel Encapsulation Attribute sub-TLV.  The Geneve tunnel
   options are encapsulated as TLVs after the Geneve base header in the
   Geneve packet as described in [I-D.ietf-nvo3-geneve].
