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, would connect to the integration bridge via a patch port as you’ve described.

Subject: [Openstack] [openstack][icehouse][neutron][floatingip][br-ex]
1. I have successfully configured floating ips in neutron and everything working fine , but as per the docs there should be int-br-ex and phy-br-int veth pair should be created between br-int and br-ex, but that is not created in my setup ,floating ip are working fine, Please suggest .
2. Added one of my nic which has connected to trunk port of switch to br-ex , I would like create multiple external networks and use each one for them for different tenants or if different tenants wants to create their own floating ip networks ,what is the solution?
Issues I am facing here are:
I . if I add multiple subnets to external network , how to create floating ip from specific subnet?
Ii . can I create multiple external networks with single L3 agent?
iii. should I create virtual interfaces like eth2.23(23 is vlan) and add them to br-ex for each vlan?
Correct me if I am wrong in understanding floating ip networks in neutron.
Here is my ovs-vsctl output:
