Hi,

I'm hoping someone can help me wrap my head around this.. The below is my scenario:

I have packstack installed OpenStack running on a CentOS 7 server on network 10.11.184.0/24. It has an IP of 10.11.184.50. It connects to this network via two bonded NICs. That is 'eno1' and 'eno2', bonded as interface 'bond0'.

I'd like to be able create instances on this very same network, and it should be able to see any other device on that network, and vice-versa.

For some reason I'm not understanding how this works from a high level, let alone any technical know-how. From my research, it appears I need to create a 'bridge' interface that bridges the network the instances live on with the physical network that the server is running on?

Can anyone kind of point me in a general direction with this so that I know I'm going down the path I need to be on?

Sorry this is so general. I will be happy to provide further information if needed.

Thanks.

How to connect your Packstack to the external world: https://community.redhat.com/blog/201.... After that, the public network in the packstack cloud will be 10.11.184.0/24.

Then you can launch the instance on public. Or you launch it on private, routed to public and with a floating IP from 10.11.184.0/24. In both cases, the instance will see and be seen by other devices with IP addresses.

I don't know about "seeing" at network layer 2 though.
