A people have mentioned that in addition to any books one may be using, Cisco.com documentation is very useful too. I'm just about to sit my ICND1 and for my ICND2 studies I want to try use Cisco.com as an additional information source.

I've found odd pages here and there whilst googling specific topics, but when I go to Cisco.com and search for something I get so many results, most of which relating to specific hardware.

E.g if I search for Network address translation I get a giant list of various releases, StarOS which I'm not even sure what is ect.

Can anyone offer me any tips on making the most out of Cisco.com to aid my studies?
