This model enables configuration of VXLAN gateways to forward local network traffic through inter-DC VXLAN tunnel. + +From the perspective of deployment, the overlay descriptor is actually a specific type of resource, a special type of Virtual Link (VL) in precise, as defined by Service Descriptor. + +Functional Requirements +----------------------- + +The following table specifies requirements to
