Abstract
In an example embodiment, packet encapsulation is employed to facilitate bridging between bridge ports that do not reflect frames (such as 802.1 compatible bridge ports) and bridge ports that do reflect frames (such as 802.11 compatible clients). Packets from a wireless access point may be sent twice, once with a predefined multicast address for processing by 802.11 clients contained in bridges, and once with the original destination address. In particular embodiments, additional means may be employed to minimize the circumstances where packets are duplicated.
