1.  Introduction

   Geneve [I-D.ietf-nvo3-geneve] is intended to support various
   scenarios of network virtualization.  In addition to carrying multi-
   protocol payload, e.g., Ethernet, IPv4/IPv6, the Geneve message
   includes metadata.  Operations, Administration, and Maintenance (OAM)
   protocols support fault management and performance monitoring
   functions necessary for comprehensive network operation.  Active OAM
   protocols, as defined in [RFC7799], use specially constructed
   packets, that are injected into the network.  To ensure that the
   measured performance metric or the detected failure of the transport
   layer are related to the particular Geneve flow, it is critical that
   these test packets share fate with overlay data packets when
   traversing the underlay network.

   This document describes several options for encapsulation of active
   OAM protocols in Geneve.  These are intended to facilitate the
   discussion among experts and all interested in both OAM and Geneve
   subjects.  The goal of such analysis is the selection of one
   encapsulation method and providing

   Also, a set of generic requirements for active OAM protocols in
