Overview – GNS3 [Graphical Network Simulator]

GNS3 stands for Graphical Network Simulator. GNS3 is a Network Simulator that lets you run virtual network devices like Routers, Switch, and Firewalls.

Since it’s an open-source tool, so you can easily run different appliances belonging to different vendors. So, you can easily practice with different products to build your carrier in networking.

GNS3 is also a cross-platform network simulator, so you can easily download and install it on Windows, Linux, and macOS-based systems.

In case, if you are a networking student and preparing for any of the Cisco Certifications, i.e. CCNA, CCNP, or CCIE, you defiantly try it out. You will get an amazing experience of virtualization.

Another best thing is that newer versions of GNS3 support QCOW files, which means you can run KVM virtual machines directly on it. So, you can able to run virtual firewalls directly on it. I am also using Firewalls, i.e. Palo Alto, Cisco ASA, and FortiGate within the GNS3.

The GUI of the GNS3 network simulator is straightforward to use. By default, you will get some pre-defined device templates. However, to use different virtual products  (i.e., Cisco/Juniper Routers, Switches, Firewalls) on GNS3, you just need to get a binary image of the devices. GNS3 supports virtual routers and switches in the IOU (IOS on Unix) and IOS (Internetworking Operating System) formats.

In GNS3, you have a facility called, u-bridge, which can be used to connect any GNS3 appliance with other virtualization applications such as VMWare Workstation and Virtual Box. So, in case, if you need to connect your Routers or Switches with any operating systems, you can connect.

Benefits of using GNS3

I am a network security engineer, and today I also using the GNS3 network simulator. The beauty of this application is that you can integrate any new application and learn it very efficiently. Since, it allows me to run firewalls such as Palo Alto, and FortiGate; I used the same tool to solve my technical issues. Some of the benefits of os using GNS3 are given below:

• GNS3 is an open-source application, so it is available to everyone.
• It’s also a cross-platform application, so you can download and install it on Windows, Linux, and macOS.
• Apart from Cisco, you can also import other vendors’ devices such as Juniper, Palo Alto, Fortinet, etc.
• When needed, we can easily integrate the GNS3 virtual devices such as Router to the other virtualization platform, i.e VMWare, Virtual Box, etc.
• GNS3 is helpful for Network and Network Security certifications such as CCNA, CCNP, CCIE, PCNSE, etc.
• The GUI of the GNS3 is very easy to use, so you can easily drag and drop installed templates. So, you can easily build new topologies and learn protocols such as OSPF, EIGRP, STP, etc.

Download GNS3 for Windows

The GNS3 network simulator is completely free for all types of operating systems. But, as you already know, the GNS3 can only be available for 64-bit Windows systems.

Since it is an open-source simulator, so you can download it from GitHub. However, if you want to download it from the official gns3 website, you need to signup on to gns3.com. Currently, the latest version of GNS3 is 2.2.16.

Note: GNS3 is a Free and Open Source software under GPL v3 licensing!

Do you Need a GNS3 VM on Linux Machine?

If you are using GNS3 Network Simulator in your Linux machine, you do not need to install and configure an additional Virtual Machine for GNS3. But you can! The main purpose of GNS3 VM is to give Unix Based IOU support to Microsoft Windows. But, in Linux, by default, you have the full support of IOU (IOS on UNIX). So, you can continue your installation process with the above instruction.

But, If you are installing GNS3 on Windows, It’s recommended you should go for GNS3 VM. Because, with the help of GNS3 VM, you can improve the overall performance of the system. Also, with the help of GNS3 VM, you can run several Cisco IOS (Routers) and IOU (Premium Switches) in comparison to GNS3 Virtual Machine Installation.

Getting Started with GNS3 – Creating the First Project in GNS3

How to add Routers and Switches in GNS3

As we know GNS3 is an open-source Network Simulator that supports Dynamips (Dynamips is an emulator computer program that was written to emulate Cisco routers). So, with the help of Dynamips, we can import any router image which is with the .bin extension.

Steps to Importing an IOS Router Image :

1. First of all open GNS3 Network Simulator
2. Go to Edit >> Preference
3. Go to IOS Router under Dynamips
4. Click New and then select New Image
5. Browse for an IOS Router Image
6. Now, just give the name and import various Interfaces according to your needs.

Creating your first Network topology in GNS3

So far, we came to know what is GNS3 where we use GNS3. In this section, we will create our first Network Topology, with the help of Cisco 7200 Series Routers. For this, first, open GNS3 and create your First Project.

After, creating a new project. Now you just have to select your Network appliances present in the left-hand pane. In this lab, I’m just taking four Routers of the Cisco 7200 series. Now, by double-clicking, you got the CLI (Command Line Interface) of the router on your Terminal or Putty(A application to take the CLI of various devices).  After that, you can configure their interface and various protocols. (i.e. Routing protocol or DHCP, DNS, etc.).

Getting Starting with Command Line Interface (CLI) in GNS3

In GNS3, after adding your first IOS (Internetwork Operating System) of the Router, you need to create a Topology as given in the above picture. Now, you need to start the appliance either by right-clicking on Network Device or clicking on the start button given below the Main Menu. After the starting of IOS, you just need to double-click to get the CLI (Command Line Interface) of that Device.

Basic Commands which can be used in GSN3

After getting the CLI of a Cisco router, you have to use commands on CLI so that you can configure your desired network topology and can work smoothly with this. Some basic commands for a Cisco Router are given below :

1. Changing the Hostname of a Router :
In GNS3, by default, the hostname of a Router is either R(1) or Router(1). When you take more than one router, the number (1) is increased by the number of routers you take. The below command can be used to change the hostname of a Router using CLI :

R1#configure terminal

R1(config)#hostname GNS3Network

GNS3Network(config)#end

2. To know Router Interfaces :
If you want to know the total number of interfaces in a router, just type the below command and you will get information about all interfaces.

show IP interface brief

2. Assigning an IP address of an Interface :
We must have to assign an IP address to get communicate with other network devices like routers, Switches, and End devices. You can assign an IP address in configuration mode. You can follow the below command to assign an IP address of an Interface:

GNS3Network#configure terminal

GNS3Network(config)#interface FastEthernet 0/0

GNS3Network(config-if)#ip address 192.168.20.1 255.255.255.0

GNS3Network(config-if)#no shutdown

How to Download and use Cisco IOU Images in GNS3

Many times, we require to create a network topology with a layer 2 or a layer 3 switch.  By default, GNS3 has an Unmanageable switch. We can’t configure them with the help of CLI. Therefore, we need Cisco IOU (IOS on Unix) to add Layer 2 or Layer 3 switches. The below steps will guide you to configure IOU Switch in GNS3 :

Importing a Cisco IOU Image in GNS3

First of all, you need a Cisco IOU Switch image with a Licence given by Cisco. To add the IOU switch, first, you need to import the IOU Switch image to GNS3. This can be done in the following steps :

• Open GNS3 Network Simulator
• Go to Edit >> Preference
• Click IOS on UNIX and Enter a valid License
  
  
• Go to IOU Devices under IOS on UNIX
• Click on New and browse for IOU Image
  
  
• Now Just give a Name to this Switch and click on finish.

Creating the First Project with Cisco IOU

Now, time to create our first project with the help of the Cisco IOU. For, this, just create a simple project. Now, take a Cisco IOU, which is just imported, and make a topology with the help of that IOU Switch. Here, I’m just taking two switches and creating VLAN (Virtual LANs) on them.

Creating VLANs on Cisco IOU Switch

After the design of the Network topology with the help of Cisco IOU, now we try to create VLANs so that we can verify the working of these switches. As you can see, we can configure the VLAN using the default commands which are used in real cisco ios switches.

L2-Switch2#configure terminal

L2-Switch2(config)#hostname GNS3Network2

GNS3Network2(config)#vlan 10

GNS3Network2(config-vlan)#name GNS3_Network

GNS3Network2(config-vlan)#end

% Applying VLAN changes may take a few minutes. Please wait…

As you know, GNS3 is a graphical network simulator program that you can easily run devices such as Cisco Switch, Router, Firewall, or virtual machine.

How to Set Up GNS3 2.2 (2.2.18) on Windows 10

With GNS3 software, you can improve yourself by making network designs and become a system and network expert. Since this network simulator has been developed in accordance with the technology by its developers, it is good to always check for updates to get new features.

Although the working logic of this program is very similar to the Cisco Packet Tracer program, the biggest difference between them is that Cisco Router and Switch IOS images can be used more comprehensively and in detail. For example, Packet Tracer includes entry-level IOS commands, while other software offers advanced commands for more advanced projects.

Minimum System Requirements

• Operating System: It should be at least Windows 7 64.
• Processor: You must have at least a Dual-Core processor.
• RAM (Memory): 4 GB minimum is sufficient.
• Disk Space: A minimum of 1 GB is sufficient. However, more space may be needed for Cisco images.

Recommended System Requirements

• Operating System: Again, it should be at least Windows 7 64 Bit.
• Processor: 4 or more logical processors. Core i7 or i9 is recommended.
• RAM (Memory): 8 GB is sufficient, but if it is 16 GB, it will be more stable.
• Disk Space: Definitely using it with an SSD disk helps you get more performance. Also, you must have a minimum of 35 GB of free space.

In addition to the system requirements of the recommended GNS3 simulator program, you can enable the virtualization setting from the BIOS menu of your computer.

Adding Router/Switch Router Image

After installing and running the Cisco simulator, you need to add an IOS image to the program. After adding and configuring the IOS images of Cisco network devices to GNS3, you will now be ready to do your projects. To add an IOS image, click on the image below and browse the related article!

Adding Routers to the Workspace and Connecting Two Routers Each Other

After adding the Router IOS image to the simulator program, you can see the device you added by clicking on Devices.

   Step 1

Now, create a new project and add two c7200 Routers to the workspace.

   Step 2

To connect the two routers, click on the cable-like vehicle and click once on R1 to view the empty ports. For example, connect one end of the network cable to the FastEthernet0/0 port of R1 and the other end to the FastEthernet0/0 interface of R2.

   Step 3

After connecting the two Cisco Routers with the FastEthernet interface, run them by clicking the start button.

   Step 4

You can open the CLI prompt by double-clicking on Router R1, or you can right-click and click Console from the displayed options.

   Step 5

To give an IP address to the FastEthernet0/0 interface of the router R1 and to activate the port, follow the commands below.

R1(config)# interface fastethernet 0/0
R1(config-if)# ip address 192.168.1.1 255.255.255.0
R1(config-if)# no shutdown

To verify that the Fa0/0 port is open, execute the following command in the CLI:

R1# show ip interface brief

   Step 6

Likewise, make the settings you have made on R1, also on R2.

R2(config)# interface fastethernet 0/0
R2(config-if)# ip address 192.168.1.2 255.255.255.0
R2(config-if)# no shutdown

Ping R1 via R2 to test the connection between the two routers.

R2# ping 192.168.1.1

How to Use SecureCRT Instead of Solar-PuTTY in GNS3

As you can see while installing GNS3, Solar-PuTTY is configured as a console application by default. However, if you do not want to use Solar-PuTTY software, you can use SecureCRT instead.

Install SecureCRT on your computer before changing the Console application.

   Step 1

After installing SecureCRT, run GNS3 again and click Edit / Preferences. In the General Preferences window, click the Edit button under General / Console Applications.

Select SecureCRT in the Choose a predefined command section and change the location where the program is installed and click the OK button to save the setting.

   Step 2

Double click on Router R1 and check if the SecureCRT console application is opened. SecureCRT works fine on GNS3 as shown below.
