This problem refers to Figure. Suppose that LAN Z is the home network for host E and that D sends a block of data to E via IP. Figure A Simple Internetworking Example LAN X Internet R1 LAN Y R3 R2 LAN Z a. Show the POU structure, incuding the fields of the IP header and the lower-level headers (MAC, LLC) with the contents of address fields indicated for the case in which E is on its home network. b. Repeat part (a) for the case in which E is on a foreign network reachable via the Internet through R3. Show formats for the MAC frame leaving D and the IP datagram leaving R3. Assume that IP-to-IP encapsulation is used. part (b) for the IP datagram leaving R3, but now assume that minima used This problem refers to Figure.
