Topology discover

Hi there,

I am currently performing a pen-test in the internal network of a company.
I am used to pen-testing systems and the set of applications they
support, looking for vulnerabilities in software version, logic or
misconfiguration.
I have also considered routing and protocol attacks as ARP spoofing and
RIP packet injection.

But I think I am missing some techniques to find out what the topology
is. I know about traceroute, firewalk and CDP, but I would like to know
if there is a whitepaper or documentation that explains how to find out
as much as possible about the enviroment I am in. Help about discovering
VLANs is also welcomed.

Thanks in advance.
