The network below shows three hosts A, B and C along with their IP and MAC addresses. Router R connects the two networks and has 2 interfaces, each of which with corresponding IP and MAC addresses. A 111.111.111.111 74-29-9C-E8-FF-55 C 222.222.222.220 1A-23-F9-CD-06-9B 111.111.111.112 CC-49-DE-DO-AB-7D 111.111.111.110 E6-E9-00-17-BB-4B a. Write Direct Delivery or Indirect Delivery for the following transfers: AB: A>C: B 222.222.222.222 49-BD-D2-C7-56-2A D 222 222 222 221 88-B2-2F-54-1A-0F b. Let's investigate the fields in the data frame for a transfer from A to C. List the destination MAC address, source MAC address, source IP and destination IP (in this order): c. Now let's look at a transfer from A to B. This transfer must go through the router R, so there will be one link layer header encapsulating the packet when it goes from A to router R, and then a second link layer header when Router R sends it out to host B. What is the source IP address and destination IP address? For the transfer from A to router R, what is the destination MAC address and the source MAC address?
