Consider an internet with two routers connecting three LANs as shown in Figure$-4.$ Each

router has three pairs of addresses, one for each connection. Although each router must have

a separate physical address for each connection, why a router needs a logical address for each

connection? The computer with logical address A and physical address $10$ needs to send a

packet to the computer with logical address $P$ and physical address $95.$ Illustrate logical

addressing for this scenario?
