Looking for network emulator

I try few emulators to practise and improve my skills for the CCNA exam,but I couldn find good emulator which one got almost all the commands,for an example there was no RIP protocol .... can you suggest me some ?

Look at this link: www.firewall.cx/ftopict-6472-gns3.html

You might also be interested in knowing that Cisco Press has recently come out with its new Cisco CCNA Network simulator - a great new tool that will allow you to work with fully simulated Cisco networks, including switches, routers and much more.

You can find more information on the Cisco Press website www.ciscopress.com/bookstore/product.asp?isbn=1587202220 .

Also expect a review on this great title very soon from us!

Cheers,
