subnets

[Guest]

My company have many departments: Marketing, Payroll, Sales, .... and so o
I'm thinking of isolate or divide them in subnets ( a subnet of sales, another for payroll, ....), and I have to consider that all of them acess resourses and files in just two servers
Can I use a only one W2K server as router to do that ? Will it increse the network traffic ? Will my network become easier to manage
Can a use manageble Switchs instead of router to inplement subnets

thanks

Can a use manageble Switchs instead of router to inplement subnets ?

You'll have to do it this way, unless you can justify placing a NIC and a
seperate hub/switch for each department on each floor...
Windows 2000 isn't 802.1q compatible as far as I know. - (VLAN Trunking
protocol).
You'll need a router to manage each vlan.
Can you justify the cost?

You can do it with a Windows Server setup to work as a router. You would
need one nic for each subnet if you plan to do it with a single "router".

Switches will acknowledge and use VLANs but will not route between them, so
you'd still need a router. There are "Layer3 Switches" out there that are a
cobination of Switch and Router in the same box, but they can be expensive.
We paid about $10,000 for ours with all the modules we required.

Subnetting reduces traffic load by reducing how far broadcasts are allow to
go. Broadcasts do not cross routers except for situations where it is
specifically setup to do so. This frees up bandwidth that would have bee
eaten up by unrestricted broadcasts.

Ease of management would be a matter of opinion. The goal of subnettting
isn't management, but is efficiency and security. The security aspect comes
from using ACLs on the router to restrict what is allows to pass to other
subnets.
