The support is also only for the VEPA mode and not for VEB mode. It's also quite not clear as how the VLAN provided by
VDP is used by libvirt to communicate it back to Openstack.</div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;">There's already an existing blueprint where i can add more details (https://blueprints.launchpad.net/neutron/+spec/netron-ml2-mechnism-driver-for-cisco-dfa-support)</div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;"><br clear="none"></div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;">Even for a single physical network, you need more parameters in the ini file. I was thinking of Host or Network Overlay with or w/o VDP for Tunnel
mode. I will add more to the blueprint.</div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;"><br clear="none"></div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;">Thanks,</div><div style="color:rgb(0, 0, 0);font-size:10.6667px;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;background-color:transparent;font-style:normal;">Paddu<br clear="none"></div><div class="yiv1985086748yqt0725194648" id="yiv1985086748yqt92650"><div class="yiv1985086748yahoo_quoted" style="display:block;"> <div style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:8pt;"> <div style="font-family:HelveticaNeue, Helvetica
