ABSTRACT:
Information is shared between switches such as bridges to facilitate efficient forwarding of data. In some embodiments consistency is maintained between information stored in filtering databases for IEEE 802.1D or 802.1Q bridges. When a switch does not have an entry in a filtering database that matches a destination address in a received frame, the switch may send information with the forwarded frame indicating that the switch had no entry for the destination address. When a switch that has an entry for a given destination address receives a frame along with an indication that the sender did not have an entry or has a different entry for the destination address, the switch may send its information corresponding to the destination address to other switches.
