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 in NVO3
   solutions. EVPN control plane can be used by a Network Virtualization
   Endpoints (NVEs) to express as well what Geneve tunnel option TLV(s)
   that they can transmit and/or receive.

1  Introduction

   The Network Virtualization over Layer 3 (NVO3) develop solutions for
   network virtualization within a data center (DC) environment that
   assumes 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
   Virtualization Encapsulation [GENEVE] have been recently recommended
   to be the proposed standard for network virtualization overlay
   encapsulation.

   This document describes how the EVPN control plane can signals Geneve
   encapsulation type in the BGP Tunnel Encapsulation Extended
   Community. The also 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 [GENEVE].
