I have uploaded and attached the VIRL file I have made for my studies. It is the ground floor topology that allows potential CCIEs like yours truly to get their hands dirty. To be used in conjunction with the INE paid workbooks or labs this topology is updated for v5. INE has moved to a virtual infrastructure with switches for their topology in alignment with the industry.
I had noted there was a lot of labs that didn’t adjust or alter the interfaces on switches themselves and therefore have represented them with multi-point connected networks. Whilst there is L2IOS within VIRL at this stage I have not dug deep enough to navigate the nuances of the image. So far I have done a lot of the routing labs without any hiccups.
Here is an image of the basic topology too. This topology has different interfaces than what is listen in the lab guides and startup configurations. Simply adjust the boot configuration if you’re loading the INE configuration.
What is great is that I know if any issues are occurring that is due to my configuration and not because of some black magic to get IOS to work. The problem I had with GNS3 is that I would waste valuable study time in tweaking and adjusting my lab due to issues with GNS3. Once you get your hands onto Cisco VIRL or Cisco Modelling Labs then you can use this file!
