Forwarding and Routing. Consider the two sub-networks from question 5).

1. Assign the MAC addresses to all the interfaces as needed

2. Assume that a host in the LAN 1 is sending a packet to another host in the same network.

i. Assume that the ARP tables in both networks are empty. What steps are needed for transmission?

ii. Assume that now the ARP tables in both networks are up to date. What steps are needed for transmission? What are the IP and MAC addresses for source and destination written in the frame of the packet at the different steps of transmission?

iii.In which situations of i) ii) does the router receive the packet and in which situation does it actually forward it?
