Thanks for suggestions, have been very useful I would select:
- Pay for a network engineer.
um-ahem. ;->
- Pay for new routers and make a more complex design for
departments.
Nah, a good layer-3 stack would do nicely. Of course, for 400 systems, that would be $5+K.
Heck, if cost is a real issue, even a layer-3 tier-1 and a layer-2 tier-2 is doable. That would be far less costly.
Remember, managed switches give you a lot of control over your network, especially routing with layer-3. It's cheaper than you think.
- just specify your network to be bigger than that. For
example 192.168.0.0-192.168.1.255 gives you 510 hosts 192.168.0.0/23
Yep, supernetting.
router-------PC with 2NICS--------Institute LAN real IP 192.168.0.0-192.168.1.255 192.168.0.0/23 Is supernetting available this way or can be used only between routers?
You don't need any routing if you're supernetting, other than to get to the Internet.
If you're going to supernet, you might as well do 4+ class Cs, or move to a class B. I recommended supernetting because I assume you don't want to have to change IPs (only subnet masks).
Actually I am with the third, because of financial issues.
Well, if you're buying equipment, you'd be surprised how little it costs to put a layer-3 GbE switch at the top. A layer-3 twelve (12) port GbE is sub-$1,000 these days.
Underneath it you can use "dumb" layer-2 switches (just FE) with GbE uplinks and at least localize somethings. That's if you're trying to do it on the cheap.
