Consider three LANs interconnected by two routers, as shown in Figure 5.38.

1. Redraw the diagram to include adapters.
2. Assign IP addresses to all of the interfaces. For Subnet 1 use addresses of the form 111.111.111.xxx; for Subnet 2 uses addresses of the form 122.222.222.xxx; and for Subnet 3 use addresses of the form 133.133.133.xxx.
3. Assign MAC addresses to all of the adapters.
4. Consider sending an IP datagram from Host A to Host F. Suppose all of the ARP tables are up to date. Enumerate all the steps, as done for the single-router example in Section 5.4.2.
5. Repeat (d), now assuming that the ARP table in the sending host is empty (and the other tables are up to date).
