oh absolutely. you can use many tools to lop off your fingers, my
point was that things like mpls (or vlans) provide a nice other tool
to use along with your firewalls and such.

of course you ought not willy-nilly go crazy with this, but... imagine
if the 'hr department' were in one contiguous 'VRF' which had a
defined set of 2-3 exit points to control access through... while
those willy 'engineers' could be stuck in their own ghetto/VRF and
have a different set of 2-3 exit points to control.

Expand your network over many locations and in large buildings and ...
it can be attractive to run a 2547 network that the company is a
'customer' of, or so I was thinking :)
