network redesign - VLAN/Subnetting
Posted on 2012-08-27
I'm in the process of building out a new facility and would like some input on the redesign of our network. Currently we have 2 buildings with a very flat network design:
Building A: 192.168.1.0 /24
Building B: 192.168.2.0 /24
The buildings are connected via point-to-point T1 routing traffic via older Cisco 1700 on Gateways 192.168.1.254 and 192.168.2.254.
Our new layout is a bit more complex and I would appreciate some assistance.
- Primary Network on 192.168.1.x
- IP Phone on 192.168.2.x
- Primary Network on 192.168.10.x
- Call Center Network on 192.168.11.x
- IP Phone on 192.168.12.x
- Misc equipment DMZ on 192.168.13.x
- IP CCTV on 192.168.14.x
Both buildings are now connected via point-to-point DS3, plus Internet, and was planning on having our firewall act as the primary gateway between the buildings and the subnets. There is not a ton of traffic between the two buildings, but there are users at each building that need access to other's networks.
I have never really played with VLAN's before and I'm not sure of the benefit of VLAN over subnetting--at least in this scenario. I would like to keep our network as flat and simple as possible, if there is such a thing anymore.
