Let me start by saying, it works. That being said, I want to ensure what I am doing makes sense because I'm slightly confused by the networking. Specifically, the bridging doesn't make sense at all. If you look at my bridging below, it appears both my public network (192.168.12.x) and my host to host management network (10.0.5.x) are getting bridged on br100. More precisely it appears my FIXED_NETWORK (11.0.4.x) as well as my public network aka FLOATING_RANGE are getting bridged to br100. I do access my openstack hosts on 192.168.12.x as well as my openstack instances on this network. I just am not understanding the networking for this set up, even though it works. </span></div><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; color: rgb(0, 0, 0); font-size: 14px; font-family: Calibri, sans-serif; "><div><br></div><div>What would be considered best practices for this case?
