We've been running out of available IP's for wireless for the past couple years and since I am in the middle of a complete network hardware swap out I'm looking at starting a redesign.
My plan is to make each building a /16, and I'm trying to decide the best route for the wireless subnets. Since the VLAN id has to be the same across all switches to simplify the wireless profiles, I see two options,
Option 1 - single /23 for each building. (With space to go to a /22 if needed)
Option 2 - individual /24's on each switch. (With the space to go to a /23 if needed)
Option 1 would be the easiest to configure, some trunk ports and a single route.
Option 2 is more to configure, Multiple DHCP scopes, firewall rules and routes.
I'm leaning towards option 2, but it seems like I'm making things very complicated.
Am I over complicating the design? I've read that wireless is fine on a /23 or /22, but I had he Wireless SE look at me like I had two heads when I told him I thinking of using a /23.
Not sure if it matters, this is a total of 5 buildings with 5 switches per.
Thank you
