If you wish to make your career in network, the Certifications is considered to be the best certification, to jump-start your career. But gaining this certification isn‘s considered to be that much easy. You have to go through lots and lots of study process unless you have the help of the CISSP Dumps offered at the ITCertDumps.

The blog is for the users who would like to simulate the router environment in GNS3VM irrespective of the vendors (Cisco, Juniper etc.)?In my earlier blog, I explained how to install and configure the GNS3 VM and how to configure a device through a template (from GNS3 Marketplace).

Today, we’ll install a device on GNS3 VM that is not available in GNS3 Marketplace (CISCO IOS).?Gns3 has a feature called Dynamips which allows us to install (CISCO IOS) image and emulate the router environment.?To perform router?installation, we need to have an IOS image.

Let’s install router C-3640 on gns3 now.

  • Step 1: Open the gns3 VM then navigate to -> Edit->preferences -> Dynamips -> IOS routers
  • Step 2: Now click on new and select option 鈥淩un IOS Router in GNS3 VM鈥?and press NEXT

Note: There is another option 鈥淩un IOS Router on Local Machine鈥?this option was used before the introduction of 鈥淕NS3 VM鈥?however, we have GNS3 VM so we will go with the latest option to achieve good performance and emulation.

  • Step 3: Now import the image of the router you would like to install on gns3 VM by clicking on option browse then say YES to 鈥渄ecompress鈥?the image.
  • Step 4: After image gets uploaded in next window 鈥?b>Assign鈥?a name to the device then platform and chassis type.

  • Step 7: Now select the idle PC value, just click on 鈥?b>idle PC-finder鈥?button to allow gns3 to input the value automatically.

Note: Idle-PC value is used for preventing the device from utilizing 100% CPU.

  • Step 8: Click on Finish to complete the installation, then click on apply and ok buttons to close the 鈥淒ynamips鈥?window

Making use of the device we have installed i.e., Router-3640.

In gns3 GUI application windows click on browse all device menu button it would look like this.

Then select the router and drag it workspace area, now click on run button or navigate to -> Control menu and click start/resume all the devices option to run the device.
