a) Examine the network configuration in the diagram below. It shows three networks connected by routers R1 and R2. Consider a scenario where host B sends a packet to host A and fill in the table below showing the addresses (IP and MAC) that would be placed in the packet headers just before each host forwards it on to the next hop. A B MAC: 29-A2-B3 IP: 128.10.0.4 MAC: 02-DE-28 IP: 192.164.0.5 R1 R2 128.10.0.0/16 10.0.0.0/8 192.164.0.0/16 U MAC: 49-11-42 IP: 128.10.0.99 MAC: 33-F3-B4 IP: 10.0.0.99 MAC: 76-8B-E2 IP: 10.0.0.125 MAC: 43-F2-BB IP: 192.164.0.125 Sender Next Hop Source MAC address address Destination MAC address Source IP address Destination IP address B R2 R1 [5 marks]
