Hi Subbareddy,, I have ended up removing the old network setup and reconfigure the network using two l3-agents as suggested in the openstack documentation (as you quoted below). I was able to associate floating ip to two pools, however, I can reach only the first floating pool ip, but not the second pool initially. I played around and I was able actually to reach both ip pools, but afterwards, I was not able to launch more instances at all, the instance stuck in the "Build" state, it apparently stuck in the "network" part, but I can not find any useful message from the log files.
I ended up going back, I used the one agent set up by following this nice blog, http://www.ajo.es/post/86497974174/using-multiple-external-networks-in-openstack-neutron I can associate floating ips for two pools, but I can not reach either of the floating ips. For tenant, I use "gre" tunnel. I am going around circle again!

You need to make sure one should be true and remaining should be false like , For the first agent handle_internal_only_routers = True gateway_external_network_id = 2118b11c-011e-4fa5-a6f1-2ca34d372c35 external_network_bridge = br-ex For the second (or later) agent handle_internal_only_routers = False gateway_external_network_id = e828e54c-850a-4e74-80a8-8b79c6a285d8 external_network_bridge = br-ex-2 Before starting L3 agents, you need to create routers and external networks, then update the configuration files with UUID of external networks and start L3 agents.

The single floating ip pool set up worked fine, but I encountered many problems setting up multiple floating IP pools. I now enabled l3-agent with empty string (in /etc/neutron/l3-agent.ini) for multiple gateway_external_network_id = external_network_bridge = The external bridges, br-ex and br-ex2, do not have the qg-* port at all, these qg-* interfaces are now in the br-int, therefore the floating ips do not work anymore. Is there any way to move "qg" port from br-int to br-ex, and br-ex2? I don't know how I ended up with such a mess, do I have to remove the network set up and reconfigure neutron? Thank you very much for your help.
