Kurt,
Interesting you should mention that. The customer did ask about using
that, as many of the other SUNY schools us it for just that purpose. But
since they've got some heavy duty equipment (6509 with dual MSFC2 serving
2000 workstations), I figure I'd try the Cisco way first. How are the
routers working out for you?
