<div dir="ltr">The main barrier to this is that we need to stop using the 'external_network_bridge = br-ex' option for the L3 agent and define a bridge mapping on the L2 agent. Otherwise the external network is treated as a special case and the VMs won't actually be able to get wired into the external network.</div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 31, 2016 at 12:58 PM, Sean Dague <span dir="ltr"><<a href="mailto:sean@dague.net" target="_blank">sean@dague.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 03/31/2016 01:23 PM, Monty Taylor wrote:<br>
