When a WAN Edge device joins the SD-WAN overlay, which Cisco SD-WAN components orchestrates the connection between the WAN Edge device and a vSmart controller?

vManage is the network management system and does not directly orchestrate the control plane connection between a vEdge and vSmart.

The vBond controller acts as the orchestrator in the Cisco SD-WAN solution, facilitating the initial discovery, authentication, and authorization of a WAN Edge device. It then directs the WAN Edge to the appropriate vSmart controller to establish its control plane connection, ensuring a secure and policy-driven overlay.

OMP (Overlay Management Protocol) is a routing protocol used for exchanging network reachability and policy information, not for orchestrating initial device connections.

APIC-EM (Application Policy Infrastructure Controller Enterprise Module) is a Cisco enterprise network controller for traditional networks and is not part of the Cisco SD-WAN architecture.
