Hello,

I already finished first nic task which can do external network.

https://www.rdoproject.org/networking/neutron-with-existing-external-network/

But I tried to do second again. It was failed and failed.

I already set br-ex2 and can ping as well. This should be private main exsiting network.

How can I do this task?

I succefully added second external network but I can't ping 172.16.0.0/24 instance at all after setting floating ip 172.16.0.0/24.

Below are my tasks to try br-ex2(172.16.0.0/24 , no gateway) as main exsiting network.
