VLAN size


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,

Re: VLAN size

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.

Re: VLAN size

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.
