This section describes how to install the OpenStack Networking service and its components for a single router use case: a provider router with private networks.
This figure shows the set up:

Because you run the DHCP agent and L3 agent on one node,

The configuration includes these nodes:
| Node | Description |
|---|---|
Controller |
Runs the Networking service, Identity Service, and all Compute services that are required to deploy a VM. The service must have at least two network interfaces. The first should be connected to the Management Network to communicate with the compute and network nodes. The second interface should be connected to the API/public network. |
Compute |
Runs Compute and the Networking L2 agent. This node does not have access the public network. The node must have a network interface that communicates with the controller node through the management network. The VM receives its IP address from the DHCP agent on this network. |
Network |
Runs Networking L2 agent, DHCP agent, and L3 agent. This node has access to the public network. The DHCP agent allocates IP addresses to the VMs on the network. The L3 agent performs NAT and enables the VMs to access the public network. The node must have:
