1. A method, comprising:
receiving, at a network node in a network, a data packet having a header comprising a media access control (“MAC”) destination address, wherein the MAC destination address is associated with a destination network node that is the destination of the data packet;
routing, with the network node, the data packet over open systems interconnection (“OSI”) model layer 3 or network layer of the network using the MAC destination address in the header of the data packet, wherein the data packet is routed toward the destination network node associated with the MAC destination address based on the MAC destination address in the header of the packet;
receiving, at the network node, a data frame having a header comprising a second MAC destination address that is the same as the MAC destination address in the header of the data packet; and
routing, with the network node, the data frame over OSI model layer 2 or data link layer of the network, using the same MAC destination address in the header of the data frame, wherein the data frame is routed toward the destination network node associated with the same MAC destination address based on the same MAC destination address in the header of the data frame.
