I currently have an AT&T Opt-e-man connection which is connected to my main router. There are 3 vlans which go over it to 3 separate remote sites. We are upgrading the speed of the connection and moving it to fiber. So, since my router doesn't support fiber (only a 3745), I'm going to bring it into my 4507R with a Sup II+ modules. My questions is how to transfer the sub-interface configuration that is on the router, over to the switch? Routing is already enabled since we have other VLANs.
Would something like this work on the 4507R? Port G1/1 will be connected to the providers access switch via 1000base-SX fiber.
