host host host S1 R1 S2 host host host subnet 1/2 subnet 3 3. KR, Ch. 6- P22 (slightly reworded with a modified figure). Consider the figure above for Problem 2. Provide MAC addresses and IP addresses for the interfaces at Host A, router R and Host F. Suppose Host A sends a datagram to Host F. Give the source and destination MAC addresses in the frame encapsulating this IP datagram as the frame is transmitted () from A to switch S1, (i) from Sl to router R1, (ii) from RlI to F. Also, give the source and destination IP addresses in the IP datagram encapsulated within the frame at each of these points in time
