Although not a bad idea, it will be a little difficult to convince
management that we now want to replace the controllers.
The reason for MPLS is that we could just hang all the wireless gear off a
wireless only PE, rather than requiring an extra hop from a CE.
This is a large campus network, and I am a big believer in collapsed PE/CE
for this type of environment.

The other issue is that we will still need a router to host all the SVIs.
All of our "routers" are 6500s or smaller switches and the number of
wireless users we have causes quite a load on the CPU - so regardless, we
would still need to buy an additional router.
