SD-WAN Deployment Overview


This walkthrough highlights the steps, or workflows, that you need to complete in order to deploy an SD-WAN solution using the hub-and-spoke topology with the hub device located in the service provider’s cloud. We use an NFX250 Series device as the CPE and an SRX Series device as the Hub which is located in the SP cloud. We indicate where in the CSO GUI you need to go to complete each step. The document also provides some explanation of the choices that you need to make at each step. It assumes that this is the first deployment you are attempting.

Additional information about using the GUI for any of the steps below can be found in the Contrail Service Orchestration User Guide.

We use the topology shown in Figure 1 as a reference for this SD-WAN deployment.

Before discussing the details of the deployment, we talk about the architecture of SD-WAN deployments in CSO. The architecture discussion helps to identify the specific pieces used in an SD-WAN deployment so that the flow of operations discussed later in Your First SD-WAN Deployment can be easily understood.
