With GNS3, you can build complex topologies using these Cisco IOS images. Cisco Router IOS images can also be obtained from the manufacturer’s website or from any source. However, as you prepare for the Cisco exams with GNS3, we share the most appropriate Cisco IOS images for you to use.

You need to know the Minimum Ram requirements to run Cisco Router or Switch IOS images. If you set a value for a Cisco Router IOS image that is larger than the Minimum RAM requirement, you may experience performance problems because your computer uses more processor. As a result, you can also set a higher Ram value for Cisco Routers on GNS3.

The IDLE-PC value on GNS3 is set so that a Router or Switch does not force your system. You can set the IDLE-PC value while adding a new network device in GNS3. The IDLE-PC value will be determined according to the hardware specifications of your computer.

The most suitable Cisco IOS images that can be used on the GNS3 are the c3640, c3660, c3725, c3745 and c7200 IOS images. It is a good idea to note the minimum RAM requirements of these GNS3 supported IOS images. There are several additional Cisco IOS images below. For example, if the c1700 series router is used, it will be inadequate if you design a more complex network.

    Hi,
    When trying to import the IOS files, it keeps giving me similar errors as seen below.

    This is not the correct file. The MD5 sum is 56db8c8d38c5727ec6780c5ba7e5f2f1 and should be 483e3a579a5144ec23f2f160d4b0c0e2.

    Please advise if this might be me doing something wrong? I have confirmed that the file names match exactly what is required.

    Hi, thank you for posting these and making them available. I’m a little concerned about using them though, do I need to have a Cisco Service Contract in order to use these images legitimately?

      Hello Nate! Thanks for your comment!

      You must have a hardware license to download Cisco IOS images. Cisco does not allow IOS images for emulators like Dynamips. However, Cisco wink at the use of IOS images on the GNS3 and this is a very good thing.

      You can download Cisco IOS images in many sources on the Internet. As a result, when you reach CCNP level, you will have to compulsorily use GNS3 because most commands are not supported in Packet Tracer.

      Hello there.

      Is your computer too old?

      If you received this error while adding an IOS to GNS3, restart your computer and try adding the IOS again. Probably because of the density of services behind your computer.
