GNS 3 and Cisco 1700,2600,7200 IOS in one pack


GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them.

To allow complete simulations, GNS3 is strongly linked with :

  • Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
  • Dynagen, a text-based front-end for Dynamips.
  • Pemu, a PIX emulator.

GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers. This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.

Features overview

  • Designing high quality complex network topologies.
  • Emulating Cisco routers and PIX firewalls.
  • Simulating simple Ethernet, ATM and Frame Relay switches.
  • Load and save in Dynagen’s INI-like format.
  • Image export (JPEG, PNG, BMP and XPM).

  1. hey i am a Information technology student from india.
    i am a CCNA .i am interested in networking ,please tell me the things that i should look out for ,the things that i should learn.

    secondly,we have ns in our practicals.what is the basic use of this simulator ( ia have used some for CCNA)…howis this powerful is this??

  2. Assalam o Alaikum..

    I am a student of CCNA and I have heard much about this simulator but did not use it. The reason is that i don’t have cisco ios files but as i have found here thats why i will use it Inshallah…


  3. @ramprasad
    GNS3 is just a front-end interface for Dynamips. and what is Dynamips?

    Dynamips is an emulator program that was written by Christophe Fillot to emulate Cisco routers. Dynamips runs on either Linux , Mac OS X and Windows and can emulate the hardware of the Cisco series routing platforms by directly booting an actual Cisco IOS software image into the emulator.It allows users to build complex network topologies to test the functionality of IOS on an desktop PC, without the need of an actual physical Cisco device (
    for detail info, go to here:

    you can search another IOS with Google keyword “intitle:index.of ios parent directory bin”.

    • hi aziz i encountered a problem that i used c2600 ios and used 2621xm routers. i mentioned idle pc value too,.everything went fine. then i opened console and i ws configuring stuffs suddenly its gone i tried openin console it is comin like “connecting to local host” and that window disappearin. not gettin connected again…… plz help me with this….

  4. Hi,

    I am using GNS3 for my MAC OS X. I could not find the IOS image files. Will the same image files work for MAC ? if not, where can I find them ?
    Thanks a lot


  5. Which version of IOS is included in this file and can you tell any website from where i can download switch emulator like GNS3

  6. Hi Aziz,
    can you simulate router in linux ? that mean : can we use PC to route packet like cisco router ?
    Your posts are very useful.

  7. Excellent — was having trouble with configuring GNS since last couple of days. Turns out that I didn’t have the right images. This works like a charm.

  8. what r the most good ways to say thank you to anyone who help you?? i don’t know.
    so let me say in a common way.
    you really made my day.

    God bless you

  9. pliz can anyone help me with ios images for gns3.send me the info to

    send me the links where i can get the free ios images

  10. i dont know what to do with gns.can anyone help me with how to use it.also stuck coz dont know where to get ios images for it.iam about to start my ccnp today 2nd april

    can anyone kindly attach to my email ,the links to where i can get the ios

  12. FYI, *****You CAN’T emulate Cisco Switches***** in GSN3.

    But you can install the nm-16esw in some of the routers slots(Don’t know what that is then look it up). *Note* you won’t get all the functions of say a real c3550. But hay its better then nothing. Also search the torrent sites for the iso’s… there are huge packs with routers, PIX, ASA and IDS… Look people there out there!

  13. Pls., can anyone who have d cisco router ios. Pls attach & sent 2 my email addres. I have d gns3 software 4 windows. But need the ios. Thks

  14. hi aziz thank u so much fr this help.. i hv a doubt that shud we mention odle pc value for every router or is it enough to mention it for one router….. plz help…. and can we directly ad this ios image or shud we decrypt it…..

  15. hi aziz i encountered a problem that i used c2600 ios and used 2621xm routers. i mentioned idle pc value too,.everything went fine. then i opened console and i ws configuring stuffs suddenly its gone i tried openin console it is comin like “connecting to local host” and that window disappearin. not gettin connected again…… plz help me with this….

  16. good evening for all i’m charles and this is my first time to use gns3 i v passing more dificulties to install gns3 at now i would like to get ios cisco c3640 router . i just look it for more web site but i did’nt find,so i asking at all if someone can send me this ios cisco on my tank’s u

  17. As Mr. Aziz said, GNS3 is a great front end for Dynamips.

    Jeremy Grossmann, Benjamin Marsili, Claire Goudjil and Alexey Eromenko(all french men) are the main brains behind GNS3.

    I remember how much I struggled using Boson Cisco CCNA/CCNP software and Cisco Packet Tracer software to learn CCNA topics. But Boson and packet tracer are half baked and you cannot run all the Cisco IOS commands in these software.

    You can run Cisco Router IOS on GNS3 to practice CCNA, CCNP and CCIE routing lessons.

    Only trouble is GNS3 cannot run Switching part. You still need to depend Cisco Packet Tracer for CCNA CCNP Switching part and real Cisco Switches for CCIE Switching part.

    Sad… I wish some how we could run Switching also in GNS3…

    You can download GNS3 from below location (GNU GPL license)

    You can download files which you require for GNS3 from below links. You may need to register and sign in.

    Thank you all…
