In the SD-WAN Solution, the RR and CPE cannot be the same device.

The statement is incorrect. In the Huawei SD-WAN solution, it is a common and officially supported architecture to have the Route Reflector (RR) and a Customer Premises Equipment (CPE) co-located on the same physical device. This is particularly prevalent in hub-spoke topologies where the hub-CPE, typically a more powerful device at a central site, is also configured to function as the RR for the overlay network. This design simplifies the network architecture and reduces the number of required devices by consolidating roles. The hub-CPE/RR is responsible for reflecting VPN routes between spoke CPEs, enabling dynamic, full-mesh connectivity between them if required by policy.

The option "True" is incorrect because it posits a rigid architectural limitation that does not exist. The Huawei SD-WAN solution is designed with the flexibility to allow the RR function to be deployed either on a dedicated device (physical or virtual) or on a CPE device at a hub site, depending on the scale and requirements of the network.

1. Huawei SD-WAN Solution Technical White Paper. In the "Solution Architecture" section, under the description of network components, it is specified that the Route Reflector (RR) role can be deployed on a CPE at a hub site. This document outlines that for hub-spoke networking, "the hub CPEs can function as RRs to reflect routes for spoke sites." (Refer to typical architecture diagrams and component role descriptions in official Huawei SD-WAN white papers).

2. HCIP-Datacom-SD-WAN Planning and Deployment V1.0 Training Material. In the module covering "SD-WAN Networking and Route Design," the training material explicitly describes the deployment options for Route Reflectors. It states that in an enterprise with a hub-spoke topology, the AR router acting as the hub-CPE is often configured as the RR to simplify deployment. (Refer to Chapter: "SD-WAN Route Design").

3. Huawei iMaster NCE-Fabric Product Documentation. The configuration guides for the SD-WAN solution detail the process of setting up the network topology. Within these guides, the steps for configuring a hub site often include enabling the RR function on the hub CPE device itself. (Refer to Section: "Service Configuration" -> "Site-to-Internet and Site-to-Site Configuration" -> "Configuring a Hub-Spoke Topology").
