In one embodiment, a method includes obtaining traffic that is to be forwarded to a neighboring device, and determining if the neighboring device is in a state that enables the neighboring device to receive the traffic. The method also includes automatically sending a first packet to the neighboring device if the neighboring device is not in the state that enables the neighboring device to receive the traffic. The first packet includes a bit sequence arranged to cause the neighboring device to awaken itself if the neighboring device is asleep.
