<div><font face="Calibri,sans-serif"><span style="font-size: 15px;">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,
</span><span style="font-size: 15px; font-weight: bold;">would</span><span style="font-size: 15px;"> connect to the integration bridge via a patch port as you’ve described.</span></font></div>
