<br>
I managed to implement the L2GW setup purely in software, without an<br>
hardware appliance.<br>
<br>
I documented in the README file, please look at this review<br>

I have a question: do we have a name for this node where the actually<br>
bridging happens between a VXLAN tenant network and a physical L2 network ?<br>
Is it okay to call it the l2gw agent ?<br></blockquote><div><br></div><div>Historically this was called l2gw agent (node). You can find references in [1,2]</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
The l2gw plugin it self runs on the controller, so also the<br>
neutron-l2gw-plugin agent runs on the controller.<br>
<br>
I think it necessary to clarify this naming, because before trying the<br>
software I did the mistake of thinking that the neutron-l2gw-agent had<br>
to run on the switch where the actual briding happens.<br></blockquote><div><br></div><div>The l2gw agent uses solely OVSDB to interact to the server and as such it can run anywhere. In fact, in Arista's POC video [3] (credit to Sukhdev), the demo setup shows this in more details.</div><div><br></div><div>Cheers,</div><div>Armando</div><div><br></div><div><div>[1] <a href="https://github.com/openstack/networking-l2gw/blob/master/doc/source/images/L2GW_deployment.png">https://github.com/openstack/networking-l2gw/blob/master/doc/source/images/L2GW_deployment.png</a></div><div>[2] <a href="https://github.com/openstack/networking-l2gw/blob/master/specs/kilo/l2-gateway-api-implementation.rst">https://github.com/openstack/networking-l2gw/blob/master/specs/kilo/l2-gateway-api-implementation.rst</a></div></div><div>[3] <a href="https://www.youtube.com/watch?v=WpilpgPnYrE">https://www.youtube.com/watch?v=WpilpgPnYrE</a></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
