<p class="MsoNormal"><span style="font-size:11.5pt">The external bridge (br-ex), when set, is used only for the external (qg) port of the router AFAIK and does not need to connect to br-int. The internal interface of the router (qr) is connected to the integration
bridge. If floating IPs are working ok, and your router is properly routing traffic to instances, then your configuration is working properly as-is. A provider bridge, like br-eth1,
<b>would</b> connect to the integration bridge via a patch port as you’ve described.</span><o:p></o:p></p>
