Which component propagates routing information and central policies to WAN Edge devices?

Explanation:
In SD-WAN, the central control plane is responsible for carrying routing state and centralized policies to every edge device. The component that handles this dissemination is vSmart. It runs the overlay control plane, collecting routing information and enforcing policies, then pushing the resulting routing configurations and policy decisions out to all WAN Edge devices. The WAN Edges first authenticate and bootstrap through vBond, but it is vSmart that updates their routing tables and applies centralized rules across the fabric. vManage provides the management interface for provisioning and monitoring, while ISE is not part of the SD-WAN control plane.
