Comcast can deliver a layer 2 Ethernet connection (over fiber) from my new site to my "hub" data center


If you can get a layer two circuit to your DC and it's part of the WAN\MPLS just use a vlan across those two. Setup a /30 and maybe run EIGRP\OSPF depending on your equipment and the size of your network. If the VLANs you need the location to see is small you can just do static routes. Or even still you can route all traffic across the layer2 and them push your internet out of the DC too. A lot of options if you are getting a Layer 2 circuit. Think of it as nothing more then a network cable to a IDF within the same building.

Exactly, that is what is so cool about layer 2 circuits. As far as you are concerned the two ends are right next to one another (although on a slower connection than you'd have if they were physically on a LAN). With that in mind you might need to consider QoS depending on how you are going to use the circuit so you don't oversubscribe the circuit.
