visit the hacki forums and register there. You'll find many config files for CCNP & CCIE level labs.

Hello ahmednaas, i have read what you have given in much more detail, however they are configured from a linux box command prompt!. I am a newbie to linux although its was gr8 to know i can learn to config. netwks too using this. however, i am looking for CCNP simulation labs & instead of using Windows, i still have the same front end just much similar with a router prompt. Many thanks friend for your further assistances.
