Routers
Routers are the customer-premises equipment deployed at each location. They can be physical appliances or equivalent platforms that terminate WAN links and LAN segments for the site.
In the Director, Routers, also called Devices, are part of the router inventory assigned to your Customer by your Partner. Each router is identified by attributes such as its serial number and hardware type.
Before you can create a Site, the router must be available in the device list for your tenant. In most cases, this means the router has been assigned to the Customer and is not already attached to another Site.
Role in the Model
The router is the enforcement point in the SD-WAN model. It receives the configuration pushed by the Director and applies the required overlays, forwarding behavior, QoS settings, and security policies.
Most policy and overlay definitions are abstract. For example, they may refer to Labels, Traffic Rules, or Overlays rather than to a specific physical device. The Site connects these abstract definitions to a real router and to the router’s physical interfaces.
