EVPN control plane for Geneve
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].
