Abstract
Embodiments of the present invention include systems and methods for providing more efficient switching of data traffic in networks that include a link aggregation domain. In embodiments, when packets arrive at one virtual link trunking (VLT) unit via an inter-node link (INL) from a peer VLT unit in the VLT domain, the first VLT unit checks whether the Media Access Control source address (MAC SA) was learned on a VLT LAG. If the MAC SA was learned on a VLT LAG, then, in embodiments, a special packet is sent to a VLT termination unit to have it learn the MAC destination address of the original packet on a sub-LAG from which the special packet was received. Learning the MAC destination address on the sub-LAG rather than the parent LAG allows for more direct switching of future packets.
