<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">But since OVS release has not supported the NSH yet, we have to wait until NSH is added into OVS and then start to support the NSH encapsulation mechanism in

to support NSH (in IETF LC phase) because OvS has not supported NSH. Is this an official position of Neutron that OvS is the gold standard to support any new feature?<u></u><u></u></span></p>
