After our conversation, I now wish to study for my CCNP. I don't have time to take courses as it takes 6 months, do you think I can learn CCNP by self-study ? Which books do you recommend for me to learn from ? Which software should I use for simulations ? Is there a CCNA Network Simulator http://www.ciscopress.com/bookstore/product.asp?isbn=1587202166 but for CCNP ?
CCNP Study Guides are different than CCNA Guides. u should try to get Student Guide or Reference guide. both of them Great and helpful, u will find them in websites and so on, if u didnt find any of them just contact me.
About the order of courses. It could be either:
1 - Route , 2 - Switch , 3 - Troubleshoot
1 - Switch, 2 - Route , 3 - Troubleshoot
Troubleshoot course should be the last one to take, it doesn't matter which one of the others you will start with.
about simulation. the best one is GNS3 this is an Emulator to emulate cisco Routers, u can download it for free from their website www.gns3.net
