Gone were most of the computers, Ethernet switches, routers, KVM boxes, and other hardware. By using these servers as virtualization hosts, I could now create complex virtual networks quickly and easily instead of having to lug heavy boxes around the room or crawl under tables untangling network cabling. Then along came VMware and Hyper-V and pretty soon I retired most of my physical systems for a couple of high-end RAM-heavy servers. By using computers and networking gear I bought or scrounged, mostly second-hand to keep expenses down, I built physical networks that mirrored the kinds of production networks used for deployments, messaging, clustering, load-balancing, and even WAN links. But most of the experience I had with new products was gained in the lab I built, which was originally located in one of the guest bedrooms of our home.
The UNetLab/EVE-NG network emulator runs in a virtual machine so it can be set up Windows, Mac OS, or Linux computers. GNS3 server Cisco IOS XRv Upload and configuration on EVE NG or UNetLab.UNetLab is the current, stable version of the network emulator and EVE-NG is an updated version of the same tool, available as an alpha release. My allergies improved a lot after that! Advantages of a virtual network labx64 EVE - The Emulated Virtual Environment for Network, Security and DevOps.
You can experiment with various subnetting arrangements and protocols, you can test various topologies and try out different approaches to managing your network. Eve-ng is one of the best emulator to Practice with Cisco IOU/IOL images, where you can imports the image in.Virtual labs are also a great way of fleshing out an emerging idea you have for network design. And while these are not theoretical limitations — in principle, you could build a virtual network that exactly mirrors the physical network you’re planning to build — the reality is that practically speaking you won’t be able to do this because of the cost of the compute and storage resources you’ll need, even though that cost will still be far less than what it would cost to build a suitable physical lab for your project.EVE-NG runs in an isolated virtual environment. Or you can build a virtual network that simulates a small portion of a physical network at a very high resolution. The main advantage is their usefulness for testing network design concepts, and you can do this in basically two different ways: you can build a virtual network that simulates an entire physical network — or a large portion of it — though at a lower resolution of the actual physical network.

Once your virtual network contains several dozen nodes, using a home-grown lab solution is generally going to be impractical.You also can’t use a virtual network to ferret out code bugs or quirks of network devices from different vendors. Assuming that your lab has the compute resources needed to run lots of routers, firewalls, and switches along with various hosts and clients, reconfiguring such an arrangement to test different scenarios will be a headache without proper orchestration tools. They’re also not very good when it comes to scale testing, that is, for determining how many routes or sessions you need to support different types of traffic.Orchestration also becomes an issue if you’ve set up a home-grown virtual network lab and you’re trying to simulate a complex physical network. For example, the firmware version of a network device may be a factor in its performance, and virtual devices can’t mirror this aspect of physical hardware. Virtual network labs are really good for doing that, they let you see what happens to the traffic flow when your design changes or when you add new systems and networksWhat virtual network labs are generally not good for, however, is for performance testing, because the actual hardware used for the physical network comes into play here in a major way.

One more thingLet me end with one final tip about building virtual network environments. Individuals seeking various networking certifications can use it to train themselves in how to use networking hardware from vendors like Cisco, Juniper, CheckPoint, F5, and others. EVE-NV is used by a wide range of enterprises, e-learning providers, and collaborators to create virtual proof of concept networks and for building solutions for training environments. And since it’s a clientless solution it can be run in a completely isolated environment without problems even if your corporate security policies place restrictions on building testbed networks. This capability makes it relatively easy for you to programmatically generate different kinds of network lab scenarios you want to test or study.EVE-NG is another great product for multivendor network emulation.
Your second virtual environment can be one where your architects can plan and try out strategic changes to your production network. This can be useful on a daily basis for testing purposes when you want to make small changes to the design or operation of your production network. Your first virtual environment can closely resemble your production environment.
