Which plane assists in the automatic onboarding of the SD-WAN routers into the SD-WAN overlay?

The data plane is responsible for forwarding user traffic through IPsec tunnels after the overlay network and devices are established and authenticated.

The vBond orchestrator, a component of the orchestration plane, acts as the initial point of contact for all SD-WAN devices, performing mutual authentication and distributing connectivity information to establish the secure overlay network. This enables zero-touch provisioning and automatic device onboarding.

The management plane (vManage) is used for configuration, monitoring, and troubleshooting the SD-WAN fabric, not for initial device onboarding.

The control plane (vSmart controllers) establishes and maintains the network topology and routing information within the SD-WAN overlay, but not the initial onboarding process.
