New To Cisco Router

on how to start my career in field of networking.I would be very grateful if you would mention about websites.

Cisco has excellent documentation. Finding out how to navigate their website (and other vendors, such as Juniper) to get to their documentation, and reading copious amounts of will help you out no-matter-what. A lot of is boiler-plate. But read the installation guides, read the getting started with configuration guides.

Thanks Doug for replying back. But one my friends gave me collections of feww ebooks on CCNA and others. Should I need to read to them also.

I find the quality of the cisco documentation to be much better than most CCNA books, while teaching much the same info. So each to their own.

Knowing *how* to navigate the cisco documentation is going to be an essential skill too.
