We have 3 Cisco 3750 switches configured in a stack. We need to move our stack and connect a trunk to our Metro Ethernet and other routers via fiber instead of the way it is connected now with copper. Only the 3rd switch in the stack has SFP ports. We use EIGRP throughout the network. The 3rd switch only has the Standard Image on it. The first 2 switches have the Enhanced Image.
Will we be able to connect the fiber trunk to the 3rd Switch and have the routing protocol work? Is the routing points on the VLANs global for the stack and will EIGRP work?
