Why each option
The vSmart controller is the SD-WAN control plane responsible for distributing OMP-based routing/policy information and sharing crypto key material among vEdge routers.
vSmart distributes crypto key information (IPsec keys) to vEdge routers via OMP, enabling them to establish authenticated and encrypted data plane tunnels with each other without requiring direct key exchange.
Configuring and monitoring vEdge routers is the responsibility of vManage, the management plane NMS.
Authenticating and authorizing vEdge routers during onboarding is the role of vBond, the orchestration plane component.
Distributing IP addresses via DHCP is a network infrastructure function and is not a responsibility of the vSmart controller.
vSmart uses OMP (Overlay Management Protocol) to distribute route prefixes, policy information, and service reachability data to all vEdge routers in the overlay, acting as the central control plane.
