You are designing a network for a small business. 

You 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 73.90.178.0/23 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.

See this link for examples of the physical and logical diagrams.

You can use any tools you like, including hand drawings (as long as I can understand them and they
look nice). 

Also include a textual description of the network which describes
the subnets you designed and allocated to each location. Here is an example.


First draft only needs to include Layer 3 diagram and Layer 2 diagram
for Site C to earn 40 points.

If first draft is totally complete (all sites and text documentation),
and there are NO ERRORS or corrections needed, you will receive the full
100 points for draft and final and you are done. If you have errors in
the first draft you will want to correct them and resubmit as final draft.
