I read this and first thought there should be no problem since each port has its own MAC address. But the bridge MAC address is that of one port, so this is a problem for getting to the bridge interface itself. The 802.1D docs also say that the forwarding database should be updated only when the state of the port that received the packet allows learning. _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
