Consider the network given in Figure $2.$

Figure $2$

A: Suppose that this network is a datagram network. Show the forwarding table in router A$,$ such that all traffic destined to host H$3$ is forwarded through interface $3.$

B$.$ Suppose that$-$this network is a datagram network. Can you write down a forwarding table in router $A,$ such that all traffic from $111$ destined to host $113$ is forwarded through intertace $3,$ while all traffic from H $2$ destined to host $113$ is forwarded through interface $4?($Hint: this is a trick question.$)$

C$.$ Now suppose that this network is a virtual circuit network and that there is one ongoing call between HI and $H3,$ and angher ongoing call between $112$ and H $3.$ Write down a forwarding

table in mouter A$,$ such that all traffic from III destined to host $113$ is forwarded through interface $3,$ while all traffic from $112$ destined to host $113$ is forwarded through interface $4.$

D$.$ Assuming the same seenario as $($c$),$ write down the forwarding tables in nodes B$,$ C$,$ and D$.$
