The example architecture with OpenStack Networking (neutron) requires one controller node, one network node, and at least one compute node. The controller node contains one network interface on the management network. The network node contains one network interface on the management network, one on the instance tunnels network, and one on the external network. The compute node contains one network interface on the management network and one on the instance tunnels network.

Network interface names vary by distribution. Traditionally, interfaces use "eth" followed by a sequential number. To cover all variations, this guide simply refers to the first interface as the interface with the lowest number, the second interface as the interface with the middle number, and the third interface as the interface with the highest number. |
Unless you intend to use the exact configuration provided in this
example architecture, you must modify the networks in this procedure to
match your environment. Also, each node must resolve the other nodes
by name in addition to IP address. For example, the
controller
name must resolve to
10.0.0.11
, the IP address of the management
interface on the controller node.

Reconfiguring network interfaces will interrupt network connectivity. We recommend using a local terminal session for these procedures. |
