Our current network is setup such that each building is on it's own vlan. We would change our setup so that we are routing between buildings instead. Our core has 3560's and the building we would like to route between have 3560's as well. My problem/question is, we have some devices in the remote buildings such as printers that are setup on vlan1 with static addresses. As soon as we change the link between the core and the remote building to a L3 link, those printers are unable to communicate with the main building since they are are the same subnet as devices in the main building. Is there a way to make routing between those devices and the rest of the network work without changing the ip address of those devices or is that the only solution?
Thanks in advance.
