On this page, I will revisit one of my favorite integrations. Taking a network simulator like eNSP and connecting it to another virtual machine housing GNS3.
I’m linking this article to a previous one I wrote in the GNS3 community here:
What I found out since posting the article above is that you have to have a VERY specific build.
The prerequisites are the following:
- Virtualbox environment.
- You would effectively be creating 2 vitual machines and using the virtualbox interfaces inside GNS3 and eNSP (Huawei) for that connection.
- the Huawei simulator is limited to certain builds. As my previous article points out, there is a build that allows the use of a ‘cloud interface’ in eNSP. If you don’t see that cloud interface, you don’t have the correct version.
- Windows 7 virtual machine.
- the eNSP simulator works well in a Windows 7 virtual machine. If you try to run it inside an 8/8.1/or 10 it crashes. I’ve already tried running it in an older environment. My guess is it has to do with how eNSP was written and the type of libraries it uses in a Windows 7 machine.
The point of this article is to sort of preface that older article posted in GNS3. I noticed I still get the occasional question about Huawei (or more importantly the Huawei simulator eNSP and I recommend performing the following tasks.
Stage 1: Gather your items (Huawei simulator, Windows 7 vm and a second vm running gns3 (with GNS3’s vm, you can run it on windows or linux).
Stage 2: Configure your virtualbox network environment. Use HOST ONLY networks to ensure your using the same interfaces handled by that virtual box server. (see https://integrater.tech/about/whitehat/virtualbox-basics-1-local-host-networks/ for more information.)
Stage 3: Follow the article or ‘script’ found at GNS3.com here: https://gns3.com/news/article/connecting-huawei-ensp-to-gns3
Once you have passed all three stages, you will be able to ping between the two environments and you can then create a cool sandbox where Huawei is a branch located in ‘China’ (the huawei eNSP topology in the Windows 7 machine) and then create a typical Cisco US branch in the GNS3 topology in the second vm.
