                Base YANG Data Model for NVO3 Protocols
                      draft-ietf-nvo3-yang-cfg-03

Abstract

   This document describes the base YANG data model that can be used by
   operators to configure and manage Network Virtualization Overlay
   protocols.  The model is focused on the common configuration
   requirement of various encapsulation options, such as VXLAN, NVGRE,
   GENEVE and VXLAN-GPE.  Using this model as a starting point,
   incremental work can be done to satisfy the requirement of a specific
   encapsulation.

1.  Introduction

   Network Virtualization Overlays (NVO3), such as VXLAN [RFC7348],
   NVGRE [RFC7637], GENEVE [I-D.ietf-nvo3-geneve] and VXLAN-GPE
   [I-D.ietf-nvo3-vxlan-gpe], enable network virtualization for data
   center networks environment that assumes an IP-based underlay.

   YANG [RFC6020] is a data definition language that was introduced to
   define the contents of a conceptual data store that allows networked
   devices to be managed using NETCONF [RFC6241].  This document
   specifies a YANG data model that can be used to configure and manage
   NVO3 protocols.  The model covers the configuration of NVO3 instances
