Which SD-WAN component is responsible for distributing vSmart controllers to vEdge routers?

The vBond component plays a crucial role in the SD-WAN architecture as it is responsible for establishing trust and facilitating communication between the vSmart controllers and the vEdge routers. When a vEdge router comes online, it first reaches out to the vBond to authenticate itself. Once the vEdge has been authenticated, the vBond provides the necessary information about the available vSmart controllers. This mechanism ensures that the routers can communicate securely and efficiently with the appropriate controllers, allowing for the distribution of policies and management functions essential for the operation of the SD-WAN.

The vManager is primarily responsible for the centralized management and provisioning of the SD-WAN environment, whereas the vRouter is not a component in the traditional terms of SD-WAN architecture—it typically refers to virtual routers, but is not an established part of Cisco's terminology in this context. The vEdge routers are the endpoints that connect to the network and carry traffic but do not play a role in distributing the controllers.
