What is a characteristic of vManage?

The Overlay Management Protocol (OMP) is used between vSmart controllers and WAN Edge devices for routing and policy exchange within the fabric, not primarily by vManage itself to directly 'interface' with WAN Edge devices for configuration.

While SD-WAN devices can integrate with legacy network devices via protocols like OSPF, this is a function of the WAN Edge devices, not a direct characteristic of vManage as the management platform.

While discovery involves vBond, which might have a public IP, vManage itself does not inherently require a public IP address for WAN Edge devices to discover fabric components; its primary role is management and configuration.

Cisco vManage is the central network management system for the Cisco SD-WAN solution and uses NETCONF, a robust protocol for network device configuration, to push configurations to vSmart controllers and other fabric components to build and manage the overlay network data plane.
