Can the same IP scheme be implemented to a new VLAN design?

Hello,

I have a one broadcast domain using, for example the 192.168.0.0/20 network. If a VLAN design is implemented, can the same IP scheme 192.168.0.0/20 be used or would it be something like 192.168.0.0/24 for the servers, 192.168.1.0/24 for the users, etc....?

 

Also, what determines the use of VLANS? For example, I've read that if the broadcast traffic is 20% or more then a VLAN design should be implemented. Or is it best practice to implement VLANS regardless of broadcast traffic?

 

Thank you,

Alex

Alex,

Usually the best practice is to use vlans and keep the broadcast domain small.  A common practice is to use a /24 subnet per vlan.  

192.168.0.0/24 vlan 10

192.168.1.0/24 vlan 11

192.168.2.0/24 vlan 12

and so on.
