Is this all 1 flat VLAN now ? If so, read below: If so , and you just want to migrate, I would assign a secondary address to the FE port on the Router that is a 10.x.x.x scheme that you want. This will allow you to have both active and not need to worry about what port that a PC is plugged into. Otherwise, you will be changing the IP of the PC then changing its port VLAN membership on the switch.
The method that you are trying will work, but it's a more work then you need to do if your just migrating from one IP name space to the other. If you assign a secondary address to the router, all you will need to do is to change the IP of the PC's and reboot. If your running DHCP, change its scope so it hands out 10.x.x.x address's and as the current leases expire, they will get a new one. Once all the old address space is gone, just go into the router and type the ip address 10.x.x.x.x command without secondary on the end. This will move this IP to the primary address and remove the old address from the router. Tada, your done. If you want to use separate subnets on each floor, then you would need to use sub-interfaces which I am sure others will cover in detail. If not, I will jump back in.

My main building was set up years ago with a Class C address scheme. I need to change this for a number of reasons and am planning to move it to a 10.X.X.X scheme. I would like to do this on a gradual basis. My building contains the following equipment: 7206VXR router that does internal routing. I have one FastEthernet port on this router. One Catalyst 4006 (Sup2, set based code) switch on the third floor. Both these devices run the latest code. The first and second floors have Catalyst 3500 switches with fiber between floors. A VTP domain is set up between the 3 switches. It was suggested to me to put 3 subinterfaces on the fastethernet port on the router and then trunk them to the switch (or switches). I'm not quite sure of the best way to go about doing this. I've read numerous tac articles, but a little more guidance would be greatly appreciated. Here is a sample of the code I used on the 7206 to create the subinterfaces: interface FastEthernet0/0.1 encapsulation dot1Q 111 ip address 10.50.1.1 255.255.255.0 What do I do now? The router is plugged directly into port 4/10 on the 4006. Do I create a VLAN 111 on the 4006? Any replies can be copies directly to me at [EMAIL PROTECTED] as well as to the board.
