An organization is deploying an HP SDN solution in its legacy network. The network includes OpenFlow enabled devices and legacy devices that do not support OpenFlow. How does the HP VAN SDN Controller discover multi-hop links that cross non-OpenFlow enabled switches?
A . The controller uses ARP to discover all devices on the network and then uses Open Flow to determine whether each device is OpenFlow-enabled.
B . The controller broadcasts BDDP packets that pass through legacy switches to OpenFlow-enabled switches, which send them to the controller.
C . The controller instructs OpenFlow-enabled switches to broadcast BDDP packets that pass through legacy switches to OpenFlow-enabled switches, which send them to the controller.
D . The controller broadcasts LLDP packets to discover whether connected switches are OpenFlow enabled and uses this information to create an OpenFlow topology.
