Part C is where I need the most help. 
Figure 2. Three subnets, interconnected by routers a. Assign IP addresses to all of the interfaces. For Subnet 1 use addresses of the form 192.168.1.xxx; for Subnet 2 uses addresses of the form 192.168.2.xxx; and for Subnet 3 use addresses of the form 192.168.3.xxx. b. Assign MAC addresses to all of the adapters. You may use any MAC address of your like (e.g., 0000-00-00-00-00-00-00), but please label each adapter's MAC address clearly. c. Now we replace the router between subnets 1 and 2 with a switch S1, and label the router between subnets 2 and 3 as R1. a. Consider sending an IP datagram from Host E to Host F. Will Host E ask router R1 to help forward the datagram? Why? In the Ethernet frame containing the IP datagram, what are the source and destination IP and MAC addresses? b. Suppose E would like to send an IP datagram to B, and assume that E's ARP cache does not contain B's MAC address. Will E perform an ARP query to find B's MAC address? Why? In the Ethernet frame (containing the IP datagram destined to B ) that is delivered to router R1, what are the source and destination IP and MAC addresses
