During these days, I've idea to refresh my memory for Cisco Knowledge and Install GNS3 into my Computer but GNS3 need Cisco IOS to do simulation test.
As usual, Googling then and found out a lot of Cisco IOS in some FTP site.
It's have Anonymous access and you can get what Cisco IOS uploaded in that site.
But I recommend to use FTP client Software like Filezilla to save your time.
OK. It's party time! Go to below link and have fun!
May you all be happy.
(Be knowledgeable, pass it on then)
