VXLAN) natively.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">In my case the physical appliance supports VXLAN natively, meaning it can act as a VTEP. The appliance is capable of decapsulating
packets that are received and encapsulating packets that are sent (looking at the forwarding table).

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Now we want to add the capability in the middleware/controller so that forwarding tables in the appliance can be populated and also
let the rest of infrastructure know about the physical appliance (VTEP) and its L2 info?

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">We manage the appliance through a middleware. Today, when it creates a neutron port, that is to be hosted on the physical appliance, the port is dangling. Meaning, the virtual

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Also, we want the physical appliance plugged into L2 population mechanism. Looks like the L2 population driver is distributing L2 info to all virtual infrastructure nodes where
a neutron agent is running. Can we leverage this framework? We don’t want to run the neutron agent in the physical appliance, can it run in the middle ware?
