Hi Greg,

I understand that it might be too early for NVO3, however there are already overlay tunnel implementations deployed and running out there, and the need for OAM extensions for it is undeniable.
So personally I would like to see this being discussed sooner than later so that we don’t end up with dozens of non-interoperable OAM tools.

I think that is why the authors want to discuss this in the L2VPN WG as well: it might be too early for NVO3 but there is a real need to discuss this now.

Thank you.
Jorge

Hi Kanwar, et. al,
the document is certainly interesting and very detailed. But I believe that it is rather too early to discuss applicability of particular OAM tools without agreed upon set of requirements for NVO3 OAM and comprehensive gap analysis.

Regards,
Greg

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.
