Consider the switched LAN shown below. The IP and MAC addresses are shown for nodes A, B, C and D, as well as for the router’s interfaces. An IP datagram is encapsulated in a frame and is being sent from node B to node C. What is the source MAC address of the frame at point 3? What is the destination address of the frame at point 3? What is the source MAC address of the frame at point 4? What is the destination MAC address of the frame at point 4?
