VLAN size

[ssimpel]

Hello,

I'm going to have to design a network with the following caracteristics:

- 700 users

- 20 servers

- 2 buildings linked through an optic fiber link

my problem is that ther is no real group among the 700 users, and then there is no logical reason to implement VLANs. I mean that except for the financial group, and for the servers, the rest of the users are logically speacking equal.

My question is then the following: isn't it a bit dangerous to put 700 users into a single VLAN? Is it too big, and then not safe against broadcasts?

What should I then do? Implement more VLANs, even if there is no logical need?

Thank you for your answers,

Thierry

I don't think 700 users is to big for a single vlan, depending on what kind of L3 switches you are using. If I was doing it, I would put my servers on a single a vlan, especially if they are in the same building, and vlan the buildings seperately. If your servers are spread out between buildings, then I would still run them on the same vlan and seperate the users by building/floors. The choice is yours, but for troubleshooting down the road, you may want to create different networks to make it easier to isolate problems that come up. HTH.

You might want to consider carving up vlans/subnets

by floor, then building, This would support a nice tidy addressing scheme, which would give you the ability to summarize your routes, do all sorts of

hsrp things.
