Cisco IOU L2 L3 lab with GNS3. Cisco IOS on Unix, also known as Cisco IOU, is released for internal Cisco use only.

Cisco IOU L2 L3 lab with GNS3

IOU permits to run IOS natively on x86 platform while GNS3 must emulate the whole hardware. The big difference is that IOU can run more IOS instance than GNS3, but GNS3 can run real IOS version. Psimulator2 – a graphical network simulator. Psimulator2 is a basic graphical network simulator created and used by the Czech Technical University in Prague, Faculty of Information Technology to teach basic networking topics.

Psimulator2 – a graphical network simulator

It will run on any system that supports Java, including Windows, Mac OS, and Linux. Each node created in the Psimulator2 network is a Java program that implements the functionality of a host, switch, or router. Once a network simulation scenario is started, the user can connect to each virtual node using telnet and enter configuration or test commands. However, only a sub-set of normal networking functionality is supported by the software emulation the node.

Read on to see how to set up a network using the Psimulator2 graphical user interface and run the simulation. TCP/IP. IP routing is a means of specifying and discovering paths in a TCP/IP network along which network data may be sent.


Routing uses a set of routing tables to direct the forwarding of network data packets from their source to the destination, often via many intermediary network nodes known as routers. There are two primary forms of IP routing: Static Routing and Dynamic Routing. Static routing involves manually adding IP routes to the system's routing table, and this is usually done by manipulating the routing table with the route command.

Documentation - Using the GNS3 VM - GNS3

The GNS3 VM is a Virtual Machine that runs Ubuntu Linux and comes with all installed dependencies in order to run GNS3 labs. The VM is provided starting with version 1.4 of GNS3. Why use the GNS3 VM? So why use VM instead of running stuff locally on my computer? Installation Download Both VMWare and Virtualbox GNS3 VMs can be download from GitHub. Import Open the .ova file contained in the archive you have downloaded with VMware or VirtualBox. Things are more complicated for VMware ESXi (experts only): Import the .ova via your VMware administration interface or manually using the ovftool cli tool, it should look like the this: All About GNS3: Importing Cisco IOU VM into Virtualbox.

Setup GNS3 VM VMware ESXi - Virtualization Howto. GNS3 has definitely matured as a product and offers tremendous functionality especially if you look at the cross vendor platform support that it offers.

Setup GNS3 VM VMware ESXi - Virtualization Howto

I definitely prefer the interface of GNS3 over other products such as VIRL. VIRL is maturing and getting there as a product, but the VM Maestro interface leaves a lot to be desired. Anyways, without getting into a quick review of the differences between the different products, I wanted to write up a quick post on how to setup GNS3 VM VMware ESXi installation.

I had recently refamiliarized myself with GNS3 and it has changed a good amount since the last time I had used it. One of the bigger changes lately is the use of the GNS3 VM instead of the IOU VM that has replaced this functionality moving forward. Documentation - Downloading the GNS3 VM - GNS3. The official GNS3 VM (Virtual Machine) can be download from our Github page for the corresponding GNS3 version you run: The VM is distributed in three different flavors: VMware Workstation to be used with Workstation Pro/Player and Fusion (Recommended)VMware ESXi (For experts only)VirtualBox (No nested virtualization support)We highly recommend VMware because VirtualBox doesn't support nested virtualization, this means any VM running inside the GNS3 VM will be slow because the guest VM cannot access to your CPU virtualization instructions (VT-x or AMD-V).

This can introduce security breaches, malware outbreaks, and unwanted application traffic, which can result in lost revenues, productivity, and damage to corporate reputation. Today there is increased pressure to comply with industry regulations as well as state and federal regulations, created to enhance privacy, national security, and in many cases corporate accountability. Examples of these regulations include the Payment Card Industries (PCI) Data Security Standard, which affects all vendors who receive, store, or transmit cardholder data. In the United States, other examples include the Health Insurance Portability and Accountability Act (HIPAA) in the healthcare industry, the Gramm Leach Bliley Act (GLBA) in the financial services industry, and the Sarbanes-Oxley Act in the accounting field. Using Cisco's Subnet Game to Master Subnetting. Overview One topic that gives many new network engineers the most trouble is learning and understanding IP subnetting.

Exploring DIY Linux Router Distros - Enterprise Power for Home Users. Router lockups have been a problem for me ever since I got my first 802.11G Router in 2004. Since then, we've seen companies roll out supposed "power user" routers or routers meant for "gamers," but for some reason not a single one has alleviated the problem of having to reset the router after running for a few days. After my new "gaming" router locked up while refreshing a server list for a multiplayer game, it was the last straw and I began searching for something a little more robust. What I found was a multitude of Linux-based firewall/router distributions that were easy to install and configure and offered an enterprise level of robustness, not to mention some extra goodies for power users.

You don’t need to have any knowledge of Linux to build one of these, so don't be intimidated. All Labs - GNS3vault. Open-Source Routing and Network Simulation.
