Explanation
VPN 0, also known as the transport or management VPN, must be configured on at least one interface for Cisco vManage to integrate and communicate with WAN Edge devices in the SD-WAN overlay network.
Common mistakes.
- A. VPN 512 is used for management interfaces like GigabitEthernet0/0/0 but is not the overarching transport VPN required for general control plane communication and device integration across the SD-WAN overlay.
- B. While other VPNs handle service traffic, VPN 0 is specifically mandated for the underlying transport and control plane communication necessary for vManage and WAN Edge integration.
- C. The services VPN range 0-511 is for overlay data plane services; VPN 0 is distinct and dedicated to control plane and management traffic, making it indispensable for fabric operation.
