Hi, I have a few questions on the Linux bridge, and I would appreciate it if someone could answer them. 1. Why does a bridge have a MAC address? A bridge doesn't need a MAC address. I understand that a Linux box might offer more than a regular switch, and for that you need a MAC address. But the services should be provided by a new tap interface added to the bridge. I believe that the bridge should not even be shown by ifconfig. 2. Why does a bridge take the lowest MAC address of the interfaces connected to it? 3. When I send broadcast frames to a bridge interface (etherwake -b -i br0 00:00:00:00:00:00), the frames are received by the interfaces of the bridge. But when I send the frames to one of the interfaces, they are not broadcasted to other interfaces. I though that the bridge interface (br0) behaves the same as an interface added to the bridge, but I was mistaken. What are the differences?
