Description of problem: I refered to use existing external network for eth0 by below link

and I asked on openstack community page https://ask.openstack.org/en/question/88188/i-would-like-to-use-also-second-nic-as-existing-external-network/

I refered below link to make more external network.

one nic per one instance can work.

Can you please paste ovs-agent and l3-agent config files here? What does it mean that your vm with two nic can't work (what exactly doesn't work as you expect)? Can you please also paste routes from within your guest with two nics?

3 instance's network pictures

two interface for external public and external private instance network
Demo-Network1
192.168.100.3,  192.168.15.2
Demo-Network2
192.168.200.3,  172.16.0.3

one interface for external public instance network
Demo-Network1
192.168.100.4,  192.168.15.3

one interface for external private instance network
Demo-Network2
192.168.200.4,  172.16.0.4

192.168.15.0/24 is external public(br-ex) and 172.16.0.0/24 is external private(br-ex2) for openstack
Comment 5 Lee Yang Jae 2016-03-11 01:22:48 UTC 
192.168.15.254 in the picture is gateway ip
172.16.0.123 in the picture is another computer's private network ip
Comment 6 Lee Yang Jae 2016-03-11 01:24:38 UTC 
In two interface for external public and external private picture, you can see private ping(172.16.0.123) success but not public ping(192.168.15.254).

This bug is against a Version which has reached End of Life.
If it's still present in supported release (http://releases.openstack.org), please update Version and reopen.
