Our Entire network is on the default VLAN 1. The IP range is a /22 from 172.16.140.x – 172.16.143.x with only one gateway of 172.16.140.2 /22
What I want to do is be able to create VLANs within this IP scope while maintaining the current structure for a change over period. This way I wouldn't have to do everything in one shot. Unfortunately I do not believe that this is a feasible thing.
On my firewall I would have to create the structure like this.
Vlan 1 172.16.140.x – 172.16.143.x /22 GW- 172.16.140.2 (Already Created)
Vlan 141 172.16.141.x /24 GW- 172.16.141.1
Vlan 142 172.16.142.x /24 GW – 172.16.142.1
So when the computer/server/device is plugged into the switch it would have to be a port specific VLAN as to which network it is hopping on. Only issue is on VLAN 1 it has the 4 class C scope that overlaps the other VLAN ranges.
Any chance this is possible? If so it would make my life a ton easier for the changeover.
