Sorry for the late notification. We have updated the OAM draft that dicusses the use-case of tunnel testing and the inclusion of a Router-Alert flag as part of the VXLAN reserved bits.

Name: draft-jain-nvo3-overlay-oam Revision: 03 Title: Generic Overlay OAM and Datapath Failure Detection Document date: 2015-03-06 Group: Individual Submission Pages: 37 URL: http://www.ietf.org/internet-drafts/draft-jain-nvo3-overlay-oam-03.txt Status: https://datatracker.ietf.org/doc/draft-jain-nvo3-overlay-oam/ Htmlized: http://tools.ietf.org/html/draft-jain-nvo3-overlay-oam-03 Diff: http://www.ietf.org/rfcdiff?url2=draft-jain-nvo3-overlay-oam-03 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. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
