4. Let's consider the operation of a learning switch in the context of a network in which 6 nodes labeled A through F are star connected into an Ethernet switch. Suppose that (i) B connects with interface 1, and sends a frame to E, E connects with interface 2, (ii) E replies with a frame to B. Also suppose B has MAC address as 01-12-23-34-45-56, and E has MAC address as 62-FE-F7-11-89-A3. The switch table is initially empty. Show the state of the switch table before and after each of these events. For each of these events, identify the link(s) on which the transmitted frame will be forwarded, and briefly justify your answers. A possible switching table will be like this: MAC Address Interface Time
