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

1. Consider sending an IP datagram from host E to Host B. Suppose all of the ARP tables are up-t-date. Enumerate all the steps, as done for the single router example in section 6.4.1.

2. Now repeat the previous steps assuming that the ARP table in the sending host is empty and the other tables are up to date.
