This In Focus guide provides a high-level overview of software-defined WAN (SD-WAN) and explains the tasks required to configure SD-WAN in an enterprise scenario using CSO Software as a Service (SaaS), which refers to the CSO version hosted by Juniper Networks. Figure 1 displays an SD-WAN enterprise topology for this use case.
The enterprise has one headquarters, which we model as an enterprise hub site in CSO, and two branches, which we model as two SD-WAN branch sites. Each site has two WAN links (one Internet and one MPLS) that are meshed based on matching mesh tags. In addition, the enterprise is connected to a data center and is reachable by using a dynamic route; in CSO, we model this by using a dynamically routed LAN segment.
In this guide, we provide step-by-step instructions for configuring the enterprise hub site and the SD-WAN branch sites by using the CSO GUI. The configuration includes the workflow to add and provision the sites, and the different tasks that you need to perform after the sites are successfully provisioned. We also cover how to break out traffic directly from a site to the Internet by using an SD-WAN policy.
