I am wondering if using the same IP range address in different Non-Routed VLAN could cause some confusion for a Cat3750 switch. I would like to implement this design to streamline our polyserve implementation. Each cluster will be assign to a different VLAN but it will use the same IP address range.

If it is a pure Layer-2, then you should be fine with it. If it is a routed network by any chance, it will not work. You will see a hell lot of problems.

Hi Friend,
If you will try to configure same range ip address which is same subnet on 2 different vlan (logical) interfaces on same 3750 switch it will not accespt the same and will report a message as overlapping ip address range.
But if you assign same range ip adress on different machines in different vlans but do not create any logical interface for those vlans it will work.

I feel it's not possible to assign same IP range in different non-routed VLANs.
