No, I'm not 100% certain.  Unfortunately I don't have access to the
switch, which was setup by some well-intended folks during a hurried
weekend IP change over. ;-)

Thanks for the thought, I'll ask someone local to check into that.  What
you suggests does sound possible because once I pull a DHCP address on
to a client in the dev network, traceroutes don't show the router
between the client and hosts in the testbed network.  Hmmmm.
