Abstract: Systems, methods, and apparatus for providing a communication network free of bridge loops by providing a first message from one of two bridges and a second message in response to the first message from the other of the two bridges and establishing a communicative path if both the first and second messages were received.

Abstract: A system includes a first communication network including a first switch and a second switch connected to the first switch, a second communication network including a third switch and fourth switch coupled to the third switch, and a first computing device coupled to the first communications network through a first network interface controller (NIC) and coupled to the second communication network through a second NIC. The first computing device is configured to communicate through the first NIC first communication network until it determines that it is not receiving bridge protocol data units (BPDUs) and then to communicate through the second NIC.
