According to one embodiment, a method for asymmetrical link aggregation includes detecting a link change corresponding to a previously selected port of a first set of ports used to forward frames to one of a plurality of aggregation switches connected via the first set of ports to an access switch. The method also includes re-selecting, using the access switch, a port of the first set of ports according to a distribution algorithm that ensures that all frames with a given source address are forwarded using a single port and causes frames with different source addresses to be distributed uniformly among the first set of ports in response to detecting the link change. Also, the method includes generating and sending a fake reverse address resolution protocol (RARP) frame including the given source address of the frame from the re-selected port in response to detecting the link change.
