A method includes generating a first path request message and a second path request message at a first device of a data link group. The first device is configured to communicate via a plurality of wireless channels. The first path request message indicates a first media access control (MAC) address corresponding to a first wireless interface of the first device. The second path request message indicates a second MAC address corresponding to a second wireless interface of the first device. The method includes transmitting, via a first wireless channel, the first path request message from the first wireless interface to a second device of the data link group. The method further includes transmitting, via a second wireless channel, the second path request message from the second wireless interface to the second device. A path between devices of the data link group may span multiple wireless channels.
