By default, Virtual Networks (VNs) are isolated from one another as they exist in separate VRFs. To enable inter-VN communication:

Internal Route Leaking (C): Routes are imported/exported between VRFs on the Border Node.

External Traffic Steering (D): Traffic is sent out of the Fabric through the Border Node to an external Firewall or Gateway, which then routes the traffic back into the second VN. This is the preferred method when security inspection between VNs (e.g., Guest VN to Office VN) is required.

BGP EVPN (Border Gateway Protocol Ethernet Virtual Private Network) is the standard control plane protocol used in Huawei's SD-WAN and Fabric solutions. It acts as the 'messenger' that automatically advertises Virtual Network (VN) routes, MAC addresses, and tunnel encapsulation information between sites. This replaces the need for complex static routing or legacy protocols like RIP/OSPF for overlay communication, enabling massive scalability and automation.

In the Xinghe Intelligent Campus solution, APs (Access Points) support several automated 'Plug-and-Play' deployment methods. Option A (Registration Query Center) allows an AP to query a Huawei-hosted global database to find its assigned controller. Option C (Barcode Scanning) uses the mobile app to scan the SN (Serial Number), binding the device to a site. Option D (DHCP Option 148) allows a local DHCP server to deliver the management IP of iMaster NCE-Campus directly to the AP. Email-based deployment (B) is reserved specifically for AR routers/CPEs in SD-WAN scenarios and is not a supported method for AP onboarding.
