Correct answer: vSmart Controller.
Why this is the answer
The vSmart Controller is the centralized control plane component in Cisco SD-WAN. It establishes OMP (Overlay Management Protocol) peering sessions with all WAN Edge routers and other vSmart controllers, then uses OMP to distribute routing information (like TLOCs and service routes) and policy information throughout the overlay network. This ensures all WAN Edge routers have a consistent view of the network topology and policies. vManage is the centralized network management system, responsible for configuration, monitoring, and troubleshooting, but it doesn't distribute routes via OMP. vBond Orchestrator handles the initial authentication and orchestration of SD-WAN components. WAN Edge Routers are the data plane devices that forward traffic and peer with vSmart, but they receive, rather than distribute, the primary route and policy information via OMP.
