Multiple Overlapping Network Addresses - Help!

I administer five development networks and one admin network. The admin network connects all five development networks using a Cisco 7513 router. Access lists prevent the development networks from seeing each other.

Each development network has approx 180 hosts and consists of 17 LANS. All hostnames are the same between development networks but IP addresses are currently different.

In about one month, all development networks will use the same IP addresses. In effect, my 7513 will have five 192.168.101.222 interfaces.

I cannot change anything on, or add anything to, the development networks. I can do whatever I wish to the admin network.

I need help configuring my router to differentiate between five overlapping networks.

All the same network subnets will work in bridging mode as long as none of the hosts use a duplicate IP address. I would strongly recommend renumbering and routing these networks if you can.
