Duplicate networks

Using 2 Cisco 3750's which are connected to each other, is it possible to have, for example the 192.168.50.0 (255.255.255.0)network existing on both routers. I realise that under normal conditions that this would not be possible, but am wondering would the advanced features of the 3750 permit this network duplication safely.

Re: Duplicate networks

How are the switches connected to each other? With the stack-cable?

If so, the switches are logically one.

And as long as you don't have two different 192.168.50.0-subnets, it should never be a problem. If you have, then you need something that can do NAT-translation. Do you have the standard or enterprise IOS-image?

Re: Duplicate networks

3750's are l2/l3 switches so it really depends on how you setup the connection . Set one up with a SVI of 192.168.50.0 and then just run a single trunk link to the other 3750 and you have that subnet on both switches. It really depends on how you set it up.
