Re: Network Simulator

There are multiple out there

OPNET, NS2 (open source), GNS3 (freeware). GNS has limitations on the images it can run.

I hope it helps.

Re: Network Simulator

Hi, I too am looking for a good Network Simulator to help me in my preparation for the CCNA certification and was hoping you could share with me what you have found out.

Thanks,

Re: Network Simulator

I would suggest to check dynamips and GNS3.

Re: Network Simulator

pkampana, thank you for the feed back I will look at both of these.  I have seen a lot of good ref. to the GNS3 and that it is Freeware which is nice as I am paying for my own education on this stuff.
