See figure below where two nodes A and C are connected to a router R. Two other nodes B and D are also connected to R. Assume the "grey blob" is a switch and assume all nodes are connected over Ethernet. Answer the following questions (10 points) A 111.111.111.111 74-29-9C-E8-FF-55 C 111.111.111.112 CC-49-DE-DO-AB-7D 222.222.222.220 1A-23-F9-CD-06-9B 111.111.111.110 E6-E9-00-17-BB-4B B 222.222.222.222 49-BD-D2-C7-56-2A D 222.222.222.221 88-B2-2F-54-1A-OF Lets say Node A sends a packet to Node B through R. Assume that the A's routing table has a path to B and the next hop is R, and R's routing table has a path to B and next hop is B. Fill in the details in the same format as the details that are already provided. Also fill in the ??? Step 1: A looks up its routing table. Next hop is R's IP address ??? Step 2: A sends an ARP request on the 111.111.111.1XX network to find the MAC address of R Step 3: A receives the ARP response from R with MAC address ??? Step 4: A sends the packet to R's MAC address Step 5: R receives the packet. Fill the details below similar to the steps so far (make sure to fill in the appropriate MAC and IP addresses) Step 6: Step 7: Step 8: Step 9: Step 10:
