Abstract:
   This proposal describes a mechanism that can be used to detect Data
   Path Failures of various overlay technologies as VXLAN, NVGRE,
   MPLSoGRE and MPLSoUDP and verifying/sanity of their Control and Data
   Plane for given Overlay Segment.  This document defines the following
   for each of the above Overlay Technologies:

   o  Encapsulation of OAM Packet, such that it has same Outer and
      Overlay Header as any End-System's data going over the same
      Overlay Segment.

   o  The mechanism to trace the Underlay that is exercised by any
      Overlay Segment.

   o  Procedure to verify presence of any given Tenant VM or End-System
      within a given Overlay Segment at Overlay End-Point.

   Even though the present proposal addresses Overlay OAM for VXLAN,
   NVGRE, MPLSoGRE and MPLSoUDP, but the procedures described are
   generic enough to accommodate OAM for any other Overlay Technology.
