* The big question is do they already have the fiber connection to the
Internet? I sounds like you said that they said they already have it.
Chances are there is already a router with the correct optical interface
connected to the incoming fiber. If not you are pretty much at square 1.
Usually the ISP or Backbone Provider will either provide the router or
assist with setting it up. Chances are that along with the router (or
optical switch) they received ip addresses for the interfaces and a block of
ip addresses to use on hosts internally.
You don't really need to split this up into 3 seperate LANs, although you
could. If you did your router needs at least 3 FastEthernet Ports and you
need 3 Internet-routeable IP Blocks. That's a lot of potential IP Address
Space wasted!!!!
Or you could subnet 1 Internet-routeable IP Block to enough subnets to do
the job. Subnetting as a /26 would give you 4 subnets ... which is one more
than you need (keep one subnet as a spare for future growth), but allows you
62 (or 64 depending how you calculate it and how you set-up your routing)
hosts per subnet. You may be able to get away with only 1 FastEthernet Port
on the router ... by using "Secondary" IP Addresses as gateways (to each
subnet) on the router. This way the default route will be one of these 3 ip
addresses (say ending in .1) for the computers, depending on which LAN
subnet they are. Since switch is a layer 2 device it doesn't care about IP
Addresses and Subnets anyway, you make just one connection to the Main
Switch from your Main Internet Router
From the Main Router (or optical switch) you could connect a FastEthernet
switch as being your inside main LAN switch. You could connect host
computers (PC's) directly to this switch, or you could string out
connections from its ports to seperate Ethernet Hubs (or better, smaller
FastEthernet switches).
Each 100MB switch port gets a dedicated 100MB point-point connection for the
connected computer. So there is no collisions or half-duplex/10MB like you
would get with HUB boxes.
