Abstract: Disclosed are various embodiments for multi-homing in an extended bridge, including both multi-homing of port extenders and multi-homing of end stations. In various embodiments, a controlling bridge device receives a packet via an ingress virtual port and determines a destination virtual port link aggregation group based at least in part on a destination media access control (MAC) address of an end station in the packet. The controlling bridge device selects one of multiple egress virtual ports of the destination virtual port link aggregation group. The end station of the extended bridge is reachable through any of the egress virtual ports of the destination virtual port link aggregation group. The controlling bridge device forwards the packet through the selected egress virtual port, and the forwarded packet includes an identifier of a destination virtual port to which the end station is connected.
