Are the links L2 links or L3 links ?

What feature set do you have on the 3750 switches ie. IP Base or IP Services ?

Hi Jon,

my main switch is L3 and distribution switch is L2.

So are you doing all the inter-vlan routing or both sites on one of the 3750  switches ?

Do you need to have the same vlan in both sites or are they separate vlans.

If you had IP Services images on those 2 switches the easiest way by far would be to make both links L3 and routed between sites and then simply manipulate the routing metrics that are exchanged so one path is preferred over the other. You actually might not even need to manipulate the route metrics if the OFC link is faster than the wireless link.
