(Problem 1 - 3) Assume 4 LANs are connected by bridges as shown below figure and mac address table at each bridge is initially empty. Use following table to show updated mac address table. At bridge 1: At bridge 2: At bridge 3: LANI B Port 1 Bridgel Port Number Port 1 Port 2 LAN2 Port Number MAC Port 1 Port 2 Port Number MAC Port 1 Port 2 MAC D Port 2 LAN3 Port 1 Bridge2 E Port 1 Port 2 F Bridge3 Port 2 LAN4 H 1. Station C in LAN2 transmits a packet to station D. Which stations will receive this packet? What is the updated mac address table at each bridge after completion of this one-way transmission (C to D)? (5 points) 2. After the first transmission (C to D), station E sends a packet to station C. Which stations will receive this packet? What is the updated mac address table at each bridge after completion of this one-way transmission (E to C)? (5 points) 3. Assume all station transmit message to other stations and bridges learn all location of stations. What would be a completely updated mac address table at each bridge? (5 points)
