Yes. The usual network management software such as HP Openview's Network
Node Manager, Aprisma's Spectrum. Quite expensive, though. I have not
used Nagios [1] for network discovery in this respect but it just might
have a plugin to represent a network in the way you require. Nedi [2],
seems to do just this (check out the 'simulation' in the link below) but
I have not tested in a pen-test environment yet (it probably needs the
SNMP communities to retrieve the information from switches and routers)
