7. For each item below, indicate whether it applies to RIP, OSPF, IS-IS, BGP or none. (Choose all that apply.)

______________ Does not use metrics ______________ Internal routing protocol ______________ External routing protocol

5. Consider the diagram below, which uses unrealistic IPv4 and MAC addresses to simplify the problem. Assume the router is NOT a NAT router.

Source Host: IP Address is 2.2.2.3 MAC address is 6-6-6-6-6-6

Router A Connection: IP Address is 2.2.2.4 MAC address is 5-5-5-5-5-5

Router B Connection: IP Address is 3.3.3.3 MAC address is 4-4-4-4-4-4

Destination Host: IP Address is 3.3.3.4 MAC address is 3-3-3-3-3-3

a. Assuming the ARP caches are up to date, what are the source and destination IP addresses in the IP packet and the source and destination MAC addresses in the frame that goes from the source host to the router?

Source IP ____________________ Destination IP ____________________ Source MAC ____________________ Destination MAC ____________________

b. Assuming the ARP caches are up to date, what are the source and destination IP addresses in the IP packet and the source and destination MAC addresses in the frame that goes from the router to the destination host? Source IP ____________________ Destination IP ____________________ Source MAC ____________________ Destination MAC ____________________

c. Assume the ARP cache in the source host is empty, so it will have to ARP to find the MAC address of the Router A connection. What are the source and destination MAC addresses in the ARP request? What are the source and destination addresses in the ARP response? Source MAC in ARP request ____________________ Destination MAC in ARP request ____________________ Source MAC in ARP response ____________________ Destination MAC in ARP response ____________________
