First, why install GNS3In short, it is a graphical front-end for dynamips, which is easier to use and more operable than a virtual software that uses dynamips directly. A more important point is that many of the experiments that are not implemented or completed on Cisco Packet Tracer by a number of Cisco Labs can be done well on GNS3.Second, installation environment1. System version: Windows 10 1803 Pro (ot

The concept, installation, configuration, and use of GNS3 are described earlier, and this article describes how to use the GNS3 configuration IOU to enable routing Exchange experiments using GNS3 and Cisco IOU.Since this is a long story, I'll go through the outline first:1. Introduction to IOU Simulation environment2. Preparation of IOU Software environment3. Ins

1, GNS3 IntroductionGNS3 is a graphical network virtual software that can run on multiple platforms (Windows,linux,mac OS). We can use it to learn about Cisco's certifications, or to verify the configuration that will be deployed in a production environment. It simulates running Cisco and Juniper's network devices, including routers, switches, firewalls, and more.For more detailed information, please visit its official website. http://www.gns3.net/Q:

In Linux (Fedora16), four packages must be installed before GNS3 is used. You can use yum to install the required packages. By default, four packages are available in the source. We recommend that you use 163 of the source, which is extremely fast, the default source is too slow. 1. First install the four required packages, open the terminal, and switch to the root.

Using GNS3 and Cisco IOU to build routing exchange experiments-concept paperWhen it comes to simulators, everyone is familiar with Hyper-V, VMware, and VirtualBox operating system simulators (virtual machines), as well as emulators such as QEMU, which are commonly used in UNIX and Linux, which are object-oriented simulators. There are also arcade game simulators for arcade-oriented objects. Network simulator for network device or network operating sys

How to associate GNS3 with a real NIC/how to simulate a switchI believe someone is familiar with the GNS3 network simulator, but I find that some people around me will not even use PT. Of course, I am not degrading packet tracer. He has his value. So what is the difference between GNS3 and PT? Obviously, if you want to experiment with NA, you can still use PT, bu

During the experiment, you may need to do a lot of steps in the Early Stage: for example, name the router, logg syn. no ip domain look-up. no exec-t. Of course, you can also write it in notepad and paste it again. However, such steps are of course troublesome. Especially when giving lectures to students. This is even more time-consuming. Today, I got a question about how to associate GNS3 with SecureCRT and automatically perform the preliminary steps
