It sounds a bit like you might have an ISP network that connects to multiple different customers?

That's incorrect and as others have said, it's a bad idea..

Re: Layer 3 and 2 question. [7:69576]
I'm not sure I understand the question correctly, but I do know that it is never a good idea to duplicate IP addresses on your network. This can only lead to trouble. My advice would be, don't do it.

Layer 3 and 2 question. [7:69576]
I am planning to configured both my core and distributions as L3 device, and let the access switch to distribution using L2. I was advice that by doing this on my network two identical ip address on same subnet/vlan but in a different access switch can exist. And a packet that is attend to a host in the different switch might end up in the else where. Is this real?. Sorry, but I have never think off this before.
