At our colocation facility, my company current has two 100mb circuits for internet connectivity, each connecting to a router. We are scaling back at this colocation facility and will be dropping one of the circuits, but combining the allocated IP's to the single remaining circuit. Can I connect the remaining circuit with the combined IP's and the two routers to a switch? or do I need to reconfigure one of the routers to handles all the IP's? Diagram for clarity attached. Thanks.
