Build this architecture in the Cisco Packet Tracer. Make sure that all the NICs of the machines and routers are similar $($I advise you to take the Fast Ethernet NICs to be compatible all over the network$).$ For this purpose, use the PT$-$Empty router, add to it the network interfaces labelled PT$-$ROUTER$-$NM$-1$CFE $($don$\text{'}$t forget to turn off the router before adding the interfaces and then turn it on$)$
