Can CML support multivendor topologies? Can you use other vendor VMs with CML? These are often asked questions. In this video I’m going to show you how to run a Windows 10 Virtual Machine (VM) in Cisco CML (VIRL 2).

Be warned! There are a number of steps required to make this work, but it’s definitely possible.

This is Part 7 of my CML (VIRL 2) series showing you how to download, install and configure Cisco VIRL 2 (CML-P). The new version of Cisco VIRL allows you to create virtual Cisco networks using just your Web browser. You don’t have to use a thick client or any other software – everything is included and everything is easy to use.

The new version of Cisco CML is one of your best options for CCNA, CCNP and CCIE Labs. CML has multiple advantages over other platforms such as GNS3 or EVE-NG. CML supports an HTML5 web client and contains all the Cisco IOS images. You don’t have to use a thick client like you do with GNS3. You don’t have to follow a convoluted process to get Cisco images working like you do with EVE-NG.

You don’t have to try to find images as they are all included as part of your CML subscription and by simply mapping an ISO drive to your virtual machine you can immediately start using all Cisco IOS images in your topologies. Both EVE-NG and GNS3 require that you provide your own IOS images – typically they recommend that you buy a CML subscription anyway. That means that you are already paying for CML.

CML (VIRL2) is also an official Cisco product – that means that you don’t have to worry about any gray legal issues with regards to running Cisco IOS images on your laptop. This is an official Cisco product that is supported by Cisco. By paying your yearly subscription fee of $199, you can use Cisco IOS images such as IOSv, IOSvL2, ASAv, NX-OSv and others without any worries. CML (VIRL 2) has everything you need to get started.

Disadvantages include the requirement to license your installation. That however has been simplified dramatically from previous releases. There is also a 20 node limited in topologies. However, for most of us that is fine for a lot of labs.

Is VIRL better than GNS3 or EVE-NG? In many ways it is. But, all platforms have advantages and disadvantages. If you are studying for your ccie, you many prefer gns3 or eve-ng as they don’t limit the number of devices in a topology like virl does. VIRL-PE limits you to 20 devices – so your topologies cannot be massive like they could with gns3 or eve ng. However, if you are studying for your ccna or ccnp, VIRL may be more than enough.

Cisco have made massive changes to their certification programs and it is fantastic to see the new version of VIRL in action.
