You are designing a network for a small business. Your available the following equipment: Gigabit Manageable Ethernet switches 48 port switches 24 port switches 8 port switches You can use any number of these switches. You do not have to use every port on any switch. Document the unused ports as available for later expansion. Routers with 2 Gigabit Ethernet interfaces Gi0/0 Gi0/1 and one serial interface Ser0 You can use any number of these routers. You do not have to use every interface on any router. Document the unused interfaces as available for later expansion. You also have one (and only one) Router/firewall with two 1000Mbps Ethernet interfaces eth0 eth1 This company has 3 sites. Site A has 5 rooms. Site B has 1 room. Site C has 4 rooms. You are have been assigned the net block 128.60.80.0/23 by your ISP. You will link up to them with via a serial link using 64.4.5.8/30 (.9 is them, .10 is your end). At site A you have 5 rooms which need to support up to 45 hosts each. They can all be on the same subnet (but don't necessarily have to be) At site B you have 40 workstations. They should all be on the same subnet At site B you also have 25 servers behind a router/firewall. These hosts are to be firewalled from internal as well as external hosts. The router/firewall has 2 Ethernet interfaces (eth0 and eth1) At site C you have 4 rooms with 20 workstations each. They can all be on the same subnet (but don't necessarily have to be) Site A links to Site B via a dedicated Serial interface. Site B links to Site C via a dedicated Serial interface. Site C links to the ISP via a dedicated Serial interface.

Divide up the /23 you have been assigned to accommodate the needs of the site.

Produce one logical map which shows a layer 3 map of the network and includes all subnets and address ranges for each subnet. Produce documents which show each physical network, a layer 2 picture. One for each network. Also include a textual description of the network which describes the subnets you designed and allocated to each location.
