Do each of them need IP address?
Would this work....
192.168.1.x
192.168.2.x
192.168.3.x
with class C mask: 255.255.255.0

How would you connect to them with-out an IP address?

I know that they would need IP addresses. My question was whether the
IP scheme would work.

Thanks!

Well yes it would work. But it all depends what you are trying to do
and how you are trying to do it. A common architecture is creating
VLANs on one server switch, and trunking those to the switches that
need it. One VLAN would be the 'switch vlan', where the switches are
IPed and can communicate with each other. The other vlans would be
for servers, nodes, or whatever you want to setup.

The other common architecture is each switch (presuming they all
support layer 3 interfaces), owns its own vlan or set of vlans, and
advertises the rest via layer 3 routing. The benefit to this is the
elimination of spanning tree, as well as simplicity depending how your
datacenter is setup. Basically, you would still have networks for the
switches to communicate to each other, but none would be trunks and
all would need to run a routing protocol. This also requires
significant IP design as you would want to be able to summarize on
each of the switches and avoid /24 networks being everywhere.

Sorry to go off on a tangent, but the simple answer is yes it can
work, but it all depends how you are trying to design from a layer 2
and 3 perspective.........- Hide quoted text -

Originally, I was thinking of making a "flat network" for this. So,
Net1 (192.168.1.1), Net2 (192.168.1.2), and Net3 (192.168.1.3);
255.255.255.0.

I really want to keep this network as simple as possible, but at the
same time do not want to flood every network with unecessary traffics;
thus thinking that by seperating the three networks into three
seperate subnets (192.168.1.x, 192.168.2.x, 192.168.3.x) would help.
Now, I didn't know that I would have to run any routing algorithm with
this scenario. What would you suggest? EIGRP?

Hopefully I didn't just confuse you guys with that....

Thanks!
