Cisco IOS 12.4

Cisco IOS version 12.4 Collection

I use these new IOS images with GNS3. Its always better to use 12.4 IOS as they provide full command support. If you can’t buy original routers and switches, GNS3 is your rescue. Although nothing beats practicing on original equipment but if anything stands close to original gear, that is GNS3.

You can download latest GNS3 Network Emulator from gns3 website. It is a free-ware software.

  1. All the ios works works fine in all platform except for the 2600 series, none of the 2600 series works.instead it gives some sort of ghost error. dont know if something is wrong with the ios or gns3 because i have tried almost all ios from here and also other ios from other sites but none seem to be actually working. any tips here???

    1. Rashad, the 2600 series requires you to decompress them beforehand or they will not work. You can do this simply by using a program like WinRAR to decompress the image, then selecting your uncompressed image type as the image in the GNS3 options. good luck hope it works, just read that online, and google if you can’t get it

  2. I am struggling to find an IOS for my 2950 switch. I want to upgrade it from 12.1 (11) EA1 to 12.1 (12C) EA1 or any later so I can implement SSH. Can anyone help please ???

  3. SICK! i love you dude!
    I was tired of bothering my CISCO teacher its kinda shamefull that not even LEGIT CISCO Academy student are able to download ios images from the site. Now I can revive my dead 7200 YAY

  4. sir.. can u fix the link download.. i’ve try c7200 link and almost of it is a dead link… thanks…

    4shared.com/file/129172876/6f675389/c7200-pk9u2-mz124-17.html

    this one for example

  5. can someone send me the 12.2/12.4 images for a CISCO 2600 Series Router, please my email is :

    Thanks so much everyone!

  6. How do you know which IOS file of any group to download? A separate IOS is needed for every Cisco device, I assume.

    Thanks,
    Bob Miller

    1. Hi Bob, a separate IOS is required for each model range. You only need one per model and it depends on what you want to achieve. The ‘adventerprise’ per model will give you just about everything though, rather than downloading multiple copies of lesser equipped IOS.

  7. Hi, I need some help for GNS3. I installed gns3 but it keep asking me for ios image for routers. I down loaded the image but its in vlc format and couldn’t open it. please can someone help to solve this issue step by step.

  8. Can anyone help me? I am totally new to CISCO environment i wanted to do CCNA so anyone can suggest me to download the exact link for IOS or should i download all the links of IOS 1700 or else is their any particular one.
    Thanks in advance

    1. Hi Max, if you are using GNS then any one of the 1700 series will be sufficient for CCNA studies. If you have a 1700 series router then you will need to check the memory requirements against the memory you have in your router.

  9. Can anyone please let me know which image has both BGP and IPsec ( GRE over IPsec) features ?
    I tried c2600-ipbasek9-mz.124-23.bin and c3745-advsecurityk9-mz124-23.bin images, but both images does not have BGP Configuration option.

  10. No offense to the OP, but really, get a public FTP rather than using these ****ty public download websites; they really don’t work, and charge an extortionate rate for the most basic premise of downloading more than one file in parallel. Please, nobody use them. Ever.

  11. can someone of you find me a cisco 3945E advanced K9 IOS i have cisco 3945E but i cant configure ipsec plz if you find one send me a link where can i download it
