I inherited this network that I think is way too flat. They only have 2 vlans (users and Servers). I am not concerned with the users vlan, but the Servers vlan is way too flat. I am trying to break it up without causing major issues (also , trying to keep it so I don't need to hit every server to change mask, etc.)
The Server vlan layer 3 interface is configured with 10.50.0.1 /16. When they were assigning IP to the various Servers, Printers, etc.. on this vlan, they actually used a decent numbering scheme, but unfortunately, it's all on the same vlan using /16 for the mask
For example: 10.50.10.0 for server, 10.50.20.0 for printers, etc.. However, all have /16 mask and all on the same vlan.
Any ideas how to incorporate more VLAN's without destroying the whole environment? Another question, If I reconfigure the layer 3 interface with /24 subnet, would a machine with /16 subnet still communicate with the gateway?
