[Download Cisco 7200 Ios Image Gns3
Facunda Ganesh
The only IOS images currently available from Cisco, that will work with the Dynamips emulator are the c7200 images (not the c7200p images!). The images for all of the other platforms Dynamips supported hit End of Support status, and their images were removed.
GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images. In the new GNS3 1.4, there is a way to run a second category of switches and routers. These are classified as Routing and Switching virtual machines (or R+Svms) for short. What are the differences? Here are the major differences:
Only the c7200 series get newer IOS 15 images. All other platforms are now end-of-life and only support IOS 12.4. Please note that the IOSv appliance is based on IOS 15 and there are IOU (IOS on UNIX) images with IOS 15.
You will find the technology train images to contain the newest features but it may also contain the most bugs. We recommend Mainline over Technology train if you are interested on stability without the need of new features.Please see Cisco IOS Versions and Naming for more information.
When Dynamips runs an IOS image, a single instance can consume 100% of the processing time for a CPU core or thread. To remedy this, you can supply Dynamips with an Idle-PC value, to consume less CPU. This value will vary between devices/images. To help automate the process of determining a valid Idle-PC value, you can use the Idle-PC finder button when importing a supported IOS image into GNS3:
2600s have one or two Ethernet or FastEthernet interfaces on its motherboard, 3 subslots for WICs (maximum of 6 serial ports) and 1 Network Module slot (maximum of 4 Ethernet ports or 16 FastEthernet ports).
However, if you want to use Dynamips you can use the EtherSwitch module with 2600s, 3600s and 3700s Series. Keep in mind that this module works differently (it uses the vlan database etc.) and does NOT support the following features:
If you require more switching features, it is recommended to use larger Virtual Machine Switches and Routers (like the ones from VIRL) that run inside your choice of Qemu, Virtualbox or VMWare. For advanced switching IOSv and/or IOU is recommended.
Keep in mind that some devices in GNS3 might work slower than real ones. This is because the emulator software is not as good as the actual hardware. So, choose the proper devices for the best experience.

Hi Tolga .
thank you for sharing with is all these images. I have a question why these images does not need licence . are cisco images ? What are the diference betwenn these images and the cisco one.
No offense I just want to get clarify it
These ISO files are files released for educational use only. In a real world, you cannot use such files in a company because new generation hardware is used. These files are files that have been on the Internet for a long time for the purpose of working with GNS3 and for the education of students. In short, there is no problem using image files.
After you have GNS3 installed on your computer, and you have downloaded a Cisco IOS image. We will then import this image into GNS3. Open GNS3, if you are using a MAC it will look like the picture below, if you are using a PC, I believe the preferences option will be under Edit drop down.
Select new, in the bottom middle and the browse to your Cisco IOS image. Open it and hit next. You will have the option to name the router if you would like, I am going to leave mine as the default to keep it simple. I also left the next couple of screens at default, I found that it worked pretty seamlessly when I did. I would recommend filling in slots 0-3 on your router so you will will have 4 ports to use when you are finished. Slot 0 should auto fill, for this example I selected PA-FE-TX for slots 1 and 2, and PA-GE for slot 3. This essentially gave me 3 FastEthernet ports along with a GigabitEthernet port (that is actually a realistic layout). Then hit next and you have successfully imported your Cisco IOS image!
Now all you have to do is click the router icon on the left side and you will see your router and name (mine was c7200)!! Drag and drop a few into the work space. You can connect them with the add link option, it is the ethernet cable icon. Once you are ready to start configuring the routers power them on with the green play button. The red lights will then turn green. You will be able to right click on the routers and select console. From there, everything should work just like a real router would. You can see I even configured an interface on each router just for kicks.
I'm doing a lab for my internetworking course and I'm using GNS3 as the emulator. I can configure single FastEthernet interfaces on each router but I need to have two per router. I am using the c7200 image and router.
Router>enableRouter#conf tEnter configuration commands, one per line. End with CNTL/Z.Router(config)#interface f0/0Router(config-if)#ip address 172.16.1.1 255.255.255.192Router(config-if)#no shutdownRouter(config-if)#exitRouter(config)#interface f0/1 ^% Invalid input detected at '^' marker.
The neighbor of futura router is FE80::C00F:1AFF:FEA7:0, But this IP doesnot show in output of Destiny#show ipv6 interface brief. Is there some output error of show ipv6 interface brief of both the routers??
note I tested this on the newest cisco VIRL IOS that I have imported into GNS3 and I also tested on the 7200 model. So neither of the routers can use this command. this means it must be something legacy or a typo. also the 7200 gns3 image is quite a bit older than the newer cisco VIRL image that both did not work says this has probably not been an option for a while.
I tried to replicate your description, however I was able to get a neighbor adjacency without global unicast addresses on the interfaces. You might want to try to restart the EIGRP process or try bouncing the interfaces to get the adjacency to form.
