Neutron networking for compute node(s).

Hello,

Let's assume that I have the following setup for my test OpenStack:

  • 10.0.0.0/24 - Public Network (used for floating IPs) Gateway is 10.0.0.1
  • 192.168.0.0/24 - Management Network (and everything else really) Gateway is 192.168.0.1

Now I currently have two nodes as such:

Controller Node

  • eth0: 192.168.0.40
  • eth1 (br-ex): 10.0.0.40

Compute Node:

  • eth0: 192.168.0.41
  • eth1: ??

My question to you is, do I need to configure eth1 on the Compute Node as a bridge similar to br-ex on the Controller Node? Do I even need the Compute Node to be connected to the Public Network or can it pass the networking traffic over the Management Network? What is the best practice here as I cannot seem to wrap my head around this? The goal here is to begin to segregate the network traffic for performance and security reasons. Any advice?
