Campus VLAN

I currently administer 5 campuses on a flat network connected by fiber.  I just purchased 6 Cisco 3750 switches to replace the backbone switches at each campus with one at the demarc where the external router is located.

My question:  Would I be better to run all vlans back to the demarc switch and let it alone do the ip routing or should I enable ip routing on each switch with routing occuring at each campus?  There will be some vlans that will cross campus boundaries on occassion.

You could do the routing on the one switch, but then you might as well have bought only one L3 capable switch, and bought cheaper L2 switches for the rest of the network. Besides that, performance wise it’s better to spread the routing loads around, instead of just trying to do it in just one place. If you want to get cleaver, on the VLAN’s that will cross campus boundaries, you can configure the hot router standby protocol so that if one switch goes down, the other campus with that VLAN doesn’t lose routing too.

Is it possible to use ip routing on each 3750 at each location while maintaining pc's from all subnets at all locations?
