Which SD-WAN controller establishes secure control connections to WAN Edge routers and distributes routes and policies via OMP?

The vSmart controller is central to the SD-WAN overlay, establishing secure DTLS/TLS control connections with WAN Edge routers. It uses the Overlay Management Protocol (OMP) to distribute routing information, security policies, and other network policies to the WAN Edge devices, effectively orchestrating the data plane. The vBond orchestrator is responsible for initial authentication and onboarding of devices, helping them discover and connect to vManage and vSmart controllers. WAN Edge routers are the data plane devices that forward traffic according to policies received from vSmart. vManage is the centralized network management system for configuration, monitoring, and troubleshooting.
