One major concern with L3 at the access is what class of device you can
afford at the access layer and, if your access layer devices are cheaper
than your dist/core layer, whether the inevitable degradation of
facilities matters.

A 3750 in the access layer at L3 will always do less than e.g. 6500s in
the core/dist.
