Consider two LANs interconnected by a router, as shown in the figure below, with IP address

and MAC address next to each interface.

A$.$ Host A is trying to send an IP datagram to Host B$.$ Assume that Host A$\text{'}$s ARP table is

empty $($ARP query is required$).$ Please fill in the following table with IP or MAC addresses.

B$.$ Host A is now sending an IP datagram to Host D$.$ Assume all ARP tables in all hosts are up

to date $($no ARP query is required$).$ Please fill in the following table with IP or MAC addresses.
