The base network address is 129.100.0.0/16. Your task is to subnet the base network to satisfy the address requirements of the stated networks without wasting more addresses than necessary.Create at least four networks (Network A, Network B, Network C, and Network D). You will need to use two routers. You can set up the topology as you desire, as long as there are at least four networks that meet the requirements. Students may have different topologies. Just remember, if you connect the routers directly together, you must connect them with a cross-over cable (not straight-through cable).
I have always done this with one router with switches connected to 3 networks, lost what to do with two routers and four networks.
