a. A link-layer client in one subnetwork (in San Francisco [West Coast]) can use ARP to obtain the MAC address of a link-layer server on another subnetwork (in New York [East Coast]). b. Consider the following figure. In it we see a client (A) is sending email to an email server (B). Every interface along the way with corresponding IP and MAC addresses are shown. For this problem, we're interested on information as data travels along link (2). Given this information, answer the following: i. What is the Source IP of all IP packets traveling along this link? ii. What is the Destination IP of all IP packets traveling along this link? iii. Assuming Ethernet, what is the Source MAC address for link-layer frames? iv. Assuming Ethernet, what is the Destination MAC address for link-layer frames?
