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)
