Abstract
Systems, methods, and computer-readable media for preventing man-in-the-middle attacks within network, without the need to maintain trusted/un-trusted port listings on each network device. The solutions disclosed herein leverage a host database which can be present on controllers, thereby providing a centralized database instead of a per-node DHCP binding database. Systems configured according to this disclosure (1) use a flood list only for ARP packets received from the controller; and (2) unicast ARP packets to the controller before communicating the packets to other VTEPs.
