Re: Noob basic network segmenting help

I would like to break down the existing network in our building into a
subnet per floor to allow more hosts and more management of traffic

If I put a router on each floor for each new subnet what are the
implications for DHCP, domain controllers, etc? How does a host on one
subnet get a DHCP address in the correct range from a domain controller on
a different subnet?

It'd be cheaper to use one Router with enough Interfaces for each segment.

The number of segments should be tied to how many clients you have,...not
how many floors you have,...floors are irrelevant. Do one segment for every
200+/- hosts.

Ethernet begins to degrade around 250-300 hosts,..so keep a simple /24 mask
(255.255.255.0) which gives the perfect size of 254 host.

A good way to have a multi-interface Router is to buy a Layer3 Switch and
group the ports into "interfaces" associated with each segment. Do it as a
"hub and spoke" design with the Switch/Router as the logical "center".

DHCP is a no-brainer. Create a *regular* normal Scope for each subnet. No
superscopes!!! Then configure the DHCP Helper address(s) on the Router so
that the router forwards the DHCP Queries to the DHCP Server. That's
it,...there is nothing else with the DHCP.

Don't know of any documentation. This is just too "typical" for any
documentation to come to mind. It's like asking for documentation to "cross
the street". I think the most complex part for you will be documentation
for whatever Switch/Router you buy,...and that may get a bit complex.
