GNS3

Tool GNS3, a graphical network simulation software, is a cross-platform package including a GUI, a command line-based Simulation program, and a Virtual Machine. GNS3 is an open source software for building networks in a modeler environment. You can create models of computer networks and then you can use GNS3 to validate or test the behavior of such models. A simulation model typically consists of nodes and links between these nodes. Nodes represent devices such as server computers, workstations, switches/hubs, etc., while the links represent the connections between these nodes which typically configured including bandwidth and delays. You can use emulation features to change parameters such as packet loss and link load and/or you can define the type of traffic coming from one node to another node. GNS3 is a free and open-source simulator. You can run simulations in either simulation mode, which provides an integrated GUI for a network simulator, or command-line mode. It has support for IPv4, IPv6, and OSI Layer 2, Layer 3, and OSI Layer 4 protocols. GNS3 can simulate protocols such as TCP/IP, UDP/IP, IPX, and AppleTalk. GNS3 is released under the GNU GPL.

Build an OpenStack/Ceph cluster with Cumulus Networks in GNS3: part 2

Adding virtual machine images to GNS3

I’m going to assume that at this stage, you’ve got a fully working (and tested) GNS3 install on a suitably powerful Linux host. Once that is complete, the next step is to download the two virtual machine images we discussed in part 1 of this blog, and integrate them into GNS3.

In my setup, I downloaded the Cumulus VX 4.0 QCOW2 image (though you are welcome to try newer releases which should work), which you can obtain by visiting this link: https://cumulusnetworks.com/accounts/login/?next=/products/cumulus-vx/download/

I also downloaded the Ubuntu Server 18.04.4 QCOW2 image from here: https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img

Once you have downloaded these two images, the next task is to integrate them into GNS3. To do this:

Select Edit > Preferences in the GNS3 interface.

When the Preferences dialog pops up, from the left pane select QEMU VMs, then click New.

Enter a name for the Image (e.g. Cumulus VM 4.0)

Select the Qemu binary, and specify default RAM size for each instance (I used 1024MB). You can override this for each VM you create on the GNS3 canvas, so don’t worry too much about it.

Select the Console type – I used telnet for both images.

Finally browse to the image file you downloaded earlier. When asked if you want to copy the image to the default images directory, I prefer to say Yes.

Make the following additional changes once the images have been copied over:

Edit each VM and set an appropriate symbol for it – this makes the canvas easier to interpret, but has no effect on the operation of GNS3. I used: a. :/symbols/classic/ethernet_switch.svg for Cumulus VX b. :/symbols/classic/server.svg for Ubuntu Server

Change the On close setting from “Power off the VM” to “Send the shutdown signal (ACPI)” for the Ubuntu server VM’s – this ensures they cleanly shutdown when you close your GNS3 infrastructure.

With this stage complete, you can proceed to building your infrastructure on the canvas.

Build virtual infrastructure on the canvas

Once we’ve defined our QEMU VM’s, the real fun starts! We can now simply click and drag our infrastructure onto the canvas. GNS3 doesn’t support orthogonal lines for the connections, so it can be a little crowded by the time you’ve completed as complex an architecture as we are building here – however the effort is well worth it, especially when you consider that you can right click on any connection and sniff the traffic running over it! This is a great learning and investigative tool.

One important learning is this – GNS3 does not have the capability to edit the number of network connections on a device on the canvas once you’ve connected it up – you have to delete all your connections if you want to edit this property. Thus it’s worth taking some time to plan out the design or simply add more ports than you need.

You’ll also need to edit the amount of RAM some of the VM’s are allocated, and the disk sizes too. Also for our static DHCP allocations for the Cumulus VX switches you will need to set the MAC addresses recorded in the table below. Note that the sizes and values recorded in this table are the ones I have tested with -\ they should however be viewed as minimum viable values, and may need to be increased depending on how you want to test your virtualized infrastructure:

Note that all disks are created as sparse disks, and so will not occupy the amount of storage specified above. When I had fully built my demo environment, it occupied a total of around 112GB.

In general, the network topology is laid out as follows:

Mgmt01 connects to both a Cloud and a NAT device in GNS3 – the NAT device provides fast connectivity, outbound, for all VM’s on the canvas. The Cloud device is very slow, but allows you to SSH directly into your management VM if you wish. You can leave this out if you prefer.

On all other nodes, eth0 is connected to swmgmt, and is used for out-of-band management.

All OpenStack VM’s have 5 Ethernet ports. After eth0 (management), the other 4 are used in bonded pairs for the two physical networks suggested in the openstack-ansible example document. They are wired up alternatively to leaf01 and leaf02 in pairs, starting at eth3 on these switches (eth1 and eth2 were used for testing purposes in the early stages of the design and are not assigned in the current version).

The high numbered ports on the switches are used for the interconnects between the switches that enable MLAG to operate.

Your resulting canvas should look something like this:

Creating cloud-init configurations

Once you have built your infrastructure on the canvas, the next task on our list is to build a set of cloud-init ISO images. Although the Cumulus VX images have a well known default username and password that we can make use of, the Ubuntu images do not – in fact they have no default password set at all, as they expect to get this from the cloud orchestration system (e.g. OpenStack, Amazon EC2, etc.). Fortunately for us, cloud-init is built into the Ubuntu cloud images we downloaded, and can perform any of a number of tasks, from setting a default password, to configuring the network interfaces (even bonding can be set up!), and running arbitrary commands. On the first boot of every VM, cloud-init searches a well known set of locations for its configuration data, and one of these happens to be an ISO image attached to the VM. Thus we can create a small, unique ISO image for each VM that does the following:

Sets the hostname for each VM

Sets the password for the default user account (ubuntu)

Adds an SSH public key to this user account for passwordless management

Changes the boot parameters of the VM to use the old eth0, eth1,… style of network interface naming

Installs Python (to enable further automation with Ansible later on).

In addition, for our “management” VM, our cloud-init scripts go even further, both installing Ansible and even cloning the GitHub repository that accompanies this article to the home ubuntu user’s directory.

Rather than go through the code in detail here, we’ll leave you to explore it yourself, as it is all available here: https://github.com/jamesfreeman959/gns3-cumulus-openstack-ansible

Makefile’s have been placed at appropriate places in the directory structure to help you get started easily. The process for building the ISO files is as simple as:

Clone the Git repository to the machine running Ansible: a. git clone https://github.com/jamesfreeman959/gns3-cumulus-openstack-ansible

Change into the clone directory, and run “make” to generate an SSH keypair for the out-of-band management network.

Change into the “2-cloud-init” directory – in here you will find one directory named after each node you created on the canvas in the previous section. Within each subdirectory, simply run the “make” command to generate the ISO file.

On the GNS3 canvas, right click on each VM in turn and select Configure. Change to the CD/DVD tab and select the ISO image you generated in the previous step.

Once this is completed, you will find that all your VM images will have all essential configuration performed on their first boot. However don’t boot all your nodes just yet! For everything to come up cleanly, we need to configure the network in a logical sequence, the next step in which is to complete the configuration of the management node.

Configuring the management node

Right click on the mgmt01 VM and click Start. Leave all other VM’s powered off at this stage. Now when you double-click on it, a console should open and you should see the VM boot up. You will also see it reboot – this is part of the cloud-init configuration which disables persistent network port naming.

Once the reboot completes, you should be presented with a normal login prompt. If you are using the cloud-init examples that accompany this blog, log in with ubuntu/ubuntu. If all has gone well, you will have a clone of the accompanying git repository in your home directory.

In our infrastructure, our management VM is going to perform a number of important functions (as well as running the Ansible playbooks to configure the rest of the infrastructure). It will act as a DNS server for our infrastructure, and also a DHCP server with static leases defined for the Cumulus VX images. It even acts as a simple NAT router so that our infrastructure can download files from the internet, via the NAT1 cloud we placed onto the canvas.

Assuming you’ve created the infrastructure as described (including the MAC addresses), you can simply change into the 3-mgmt01 subdirectory on the git clone, and run the Ansible playbook as follows:

ansible-playbook -i inventory site.yml

When the playbook completes, all the functionality of the management VM will be configured, and we can power the out-of-band management switch.

Configuring the out-of-band management network

The out-of-band management switch is a simple, layer 2 switch – however it still needs to be told that this is its configuration. Fortunately, Cumulus Networks’ switches are easy to configure using Ansible, and a playbook is provided in the accompanying git repository. Simply change into the 4-swmgmt subdirectory, and run the playbook as follows:

ansible-playbook -i inventory site.yml

Once it completes successfully, swmgmt will be configured as a layer-2 switch for managing all the other devices on our virtual infrastructure. From here, you can power the other 4 switches.

Configuring the spine-leaf switch topology

Once the 4 switches which comprise the spine-leaf topology boot up, you can proceed to configure them. Once again, Ansible playbooks are provided for exactly this purpose. The switch configuration for these switches is a simple layer-2 MLAG configuration – more advanced configurations are possible and I’ll leave it to you to explore more advanced options – however the code provided in the accompanying repository will set up a spine and leaf topology, with the switch ports configured to support resilient bonding on all the OpenStack nodes. Note that the port configuration assumes you have wired up the virtual machines as discussed earlier in this blog, and you will need to edit the configuration if you wish to change the port assignments.

Once you are ready to configure the switches, simply run the playbook in the 5-swcore subdirectory, as follows:

ansible-playbook -i inventory site.yml

When that playbook completes successfully, you will have a fully configured infrastructure with a resilient switching architecture and bonded network configurations on all nodes. The final stage is to power up all remaining nodes, and to install OpenStack.

Deploying OpenStack

With the switching infrastructure set up, you should now be able to power on all remaining virtual machines. They will obtain all their initial configuration (including networking) from the cloud-init ISO’s we attached earlier, and will present themselves as a blank canvas on which OpenStack can be installed. It is worth noting that although I have created this as a worked example for OpenStack, you could use this to simulate just about any distributed architecture.

Installing OpenStack, even from the openstack-ansible project, is a fairly lengthy and involved process. All details are given in the README.md file of the 6-osansible subdirectory of the GitHub repository accompanying this article, so we won’t repeat them again here.

In short the process involves cloning the openstack-ansible code onto the management node, preparing the node for OpenStack deployment (a special bootstrap script is provided for this), setting appropriate variables to configure the installation, and then running the playbooks in the correct sequence. If you’ve never done this before, this can be quite a daunting task, especially when you come across issues such as the incompatibility between ceilometer and the ujson Python module that exists in the openstack-ansible 19 release.

A great deal of credit goes to the team that manage the official openstack-ansible IRC channel, without whom the creation of this demo environment would not have been possible.

Wrapping up

Although the nested virtualization that this setup takes advantage of can at times be slow, and the hardware requirements, especially in terms of memory and I/O performance are significant, the techniques we have covered here offer great potential for both training, and development purposes.

For example, you could build a real production OpenStack configuration on physical servers, using real physical Cumulus Networks powered switches using most of the same playbooks and cloud-init configuration data that we have used here. Similarly, you could simulate your production environment in GNS3 on a suitably powerful host, thus performing penetration testing, or testing new configurations, or even failure modes, to see how the environment responds. For example, you can easily power down entire sections of the GNS3 virtual infrastructure, or delete connections, in full confidence that you are not going to (accidentally or otherwise) impact any other vital services. The environment is a complete sandbox, and so is ideal for security testing, especially if you are investigating the impact of certain kinds of attacks or malware.

The opportunities provided by this kind of setup are endless, and the kindness of Cumulus Networks in making Cumulus VX available for free means you can easily simulate your real network infrastructure in a contained, virtual environment.

What is Gns3 Layer 3 Switch and How to Use Fortigate Image For Gns3

Gns3 layer 3 switch A server that has been reduced into a virtual form is all that a virtual machine is. Its simple objective is to operate the emulation of your devices from a single location, saving you a lot of resources. The GNS3 network simulator is open source, free, and accessible for download by anyone, therefore anyone can use it.

In many aspects, the Gns3 layer 3 switch mirrors the GUI of the complete product. Users of this GUI can build sophisticated labs out of a variety of compatible Cisco routers using an easy-to-use interface.

When it comes to picture viewers and photo viewers for Windows systems, there are numerous options accessible. Actually, the default Windows Photo Viewer is a decent viewer and comes with all the necessary features.

Here is a unique picture viewer for Windows; it's called Nexus Image and it's available for free.

The GNS3 network simulator is unquestionably incredibly flexible.

As you can see from the screenshots above, you can really build your own labs using the necessary tools, giving you the proper preparation for a particular Cisco exam.

Nevertheless, using GNS3 has several drawbacks. The most important is that you need your own Cisco IOS images in order to use the simulator.

Pre-configured appliances are simple to add to GNS3 and integrate into your projects and labs. In private, hybrid, and public cloud deployments, the fortigate image for gns3 Appliance provides the same level of cutting-edge threat protection functionality as the physical appliances.

In terms of training, network simulators have essentially replaced actual network labs. You can create topologies in a virtual environment and configure network devices exactly as you would their real-world, physical counterparts with the help of network simulators.

Cisco's Packet Tracer, Eve Ng's Ccnp Lab, and GNS3 are the three most widely used network simulators. In this post, we will examine and compare a number of software programs. According to network specialists, Eve-NG is the most widely used network emulator.

It is set up to function like switches, routers, firewalls, and wireless access points rather than using its original IOS image files. Due to the fact that it is a simulator, not all of the features provided by the actual software-based devices are supported entirely.

In some tritely dry words, eve ng export lab gives you tools to use around virtual devices and connect them with other virtual or physical devices. The ability to understand and share topologies, work, thoughts, concepts, or even just "labs" is considerably improved by many of its features, which also significantly increase usability, reusability, manageability, interconnection, and dissemination.

This may just mean that setting up what you need will cost less money and time, or it may also mean that you will be able to carry out tasks that you wouldn't have believed were so straightforward.

In R&S direction, we are here to talk about the entry steps:

1. On the familiar reading, from CCNA to CCNP class books, a total of five you need to read my own in detail. After reading two times is considered to be able to get started then look at the NA and NP online relevant videos to see if your understanding is the same as the tutor's explanation in the video or not and start taking notes. Further, find a training institution, attend an NP course. I joined SPOTO and the quality is quite good. Remember, the above steps it can be omitted if you would like to be a paper NA or NP

2. About practice, you have to prepare a laptop and install two recommend software as dynamic or GNS3, practice with the Lab according to the topology and then start from NA to NP experiments and practice them again and again

3. About brainstorming, in the above 1 and 2 processes, try to think, simulate the scenarios and ask a few more reasons such as when a package is sent from the computer to the website then what changes in the second and third layers of the packet? What did the Switch and Router do with these packets?

Next, we talk about the exam, preparation of the exam and before. Prepare for the exam, read TCP/IP Volume 1 and Volume 2 carefully and practice the commands with they mentioned twice. When you practice on the second time, mark the results and organize them into your own notes and it is every experiment.

For Exam preparation, firstly find a reliable training institution so that you can concentrate on preparing for the exam. Other things are supported by the lab staff (like signing up).

Secondly, you must take classes and listen to every configuration. Once again (Note: the difficulty of IE version and NP experiment is not a level at all. In 2009, 7 versions need to be sorted).

Third, prepare for the written test. In fact, the simplest one is this, because there is a question bank in general training institutions. It is suggested to reserve three days of back-to-back questions study.

Fourth, after the written test passed, estimate the time for the exam. It is recommended to leave at least three months for it to deal with those configurations and make the time requirements clear to the laboratory.

Fifth, the configuration has to be practiced at least three times. The first time you only need to follow and configure out with the result. This first practice is the most time-consuming. After finished, don't rush for the second time and study the configuration carefully in about three days. Look at the difference between your own answer and the standard answer then drop it down and ask the teacher. Try the second time and use your own answer to see if it is correct. After second practice, please ask the lab teacher or classmate to add mistakes for you, about 7 or so, it is because 3-5 mistakes usually appear during the exam, I have encountered 5. The ability to debug is based on how the previous skills have been played, that is the experiment of NA to NP and whether the experiments in Volumes 1 and 2 are serious. On the third, the back version, intensive training according to the examination arrangement and you just practice each configuration every day as usual and arrange the troubleshooting after the configuration part is finished.

Fifth, prepare before the exam, arrange the accommodation in advance, go to the exam venue one day before the exam, no longer arrange the operation review two or three days before the exam, focus on review of the configuration

From the career development of network engineers:

The general situation has the following development path. The technical support engineer job categories are:

After-sales - pre-sales - project management

After the sale, it can be divided into:

lResident engineer - To understand some techniques, but lack of project experience often used to examine and train new people

lFirst-tier engineer - Engineers who need to go to the customer site to deal with various problems. There are certain requirements for technology, and the company often trains new people to do it. If you have a tough problem, you can ask the company for help

lSupport engineer - Need a certain technical background and project experiences. When a frontline engineer encounters a problem, he should be able to give a solution as soon as possible

lSecond tier engineer - Need a lot of project experience, solid technical skills. Need to have the ability to control the project macro

lPre-sales engineer

lProject management - Not only have a certain project experience, but also a team. Team management, departmental collaboration, resource allocation, etc. all need to think

Therefore, in the process of the exam, we must also learn some experience of the project.

1. For CCNP certification, you must first obtain CCNA certification. CCIE certification does not require CCNA and CCNP and you can go for exam directly

2.Valuable content: CCNA, CCNP back question bank can be certified which is low in value

3. Some high-paying jobs require CCIE certification, while normal network engineer recruitment generally writes CCNP, HCNP priority, and so on.

About Instructor:

Mr. Mihai Catalin Teodosiu

Hi! My name is Mihai. I have a degree in Telecommunications and Information Technology from University Politehnica of Bucharest, Romania and also the CCNP, CCNA, CCDA, JNCIA and ISTQB CTFL certifications. I worked as a Network Quality Assurance Engineer since 2010, testing the OS for Nortel/Avaya L3 switches. # 6+ years experience in the Networking and Testing/Quality Assurance industries. # Certified professional: Cisco, Juniper and International Software Testing Qualifications Board certifications. # Teaching courses on Udemy, GNS3 Academy and other e-learning platforms. # Thousands of satisfied students, 4.5 / 5 average course rating. # Thousands of followers on LinkedIn, Twitter, Facebook and Blogger. See what my students are saying about the kind of courses I created: “What an incredible value and learning experience!” by Sean A. === In early 2014 I decided to start learning a programming language that can make my daily work easier and also boost my networking career. This is when I discovered that Python, being a great language for beginners, can help me write some scripts that connect to network devices and perform various tasks I was doing manually, thus saving a lot of time. Also, working as a tester, I used Python to automate a lot of network tests, about 250, in a short period of time, again reducing my workload. For all the above reasons and because there is a lot of Python material out there on the Internet that may seem discouraging for you as a beginner, I decided to build courses that take you from zero programming knowledge to advanced topics, all in a hands-on fashion. === In March 2015 I started working on my first course, “Python Network Programming – Part 1: Build 7 Python Apps”, without really knowing what is online education all about and with no prior teaching experience, either online or offline. I just wanted to try it for some reason, despite a lot of mental obstacles, a full time job and zero experience in teaching people. I worked a lot on this first course, with countless hours of researching, recording and editing, but there was something that kept me going further. In May 2015 my course was approved by Udemy and was an instant success, despite my low expectations. Gradually, the course became a bestseller on other e-learning platforms, as well. One example I’m very proud of is the GNS3 Academy. In April 2016, I finished working on Part 2 of the Python Network Programming series, called “Multivendor Environment”, after about three months of researching, testing, summarizing, simplifying, recording, editing and structuring the course content. Finally, in September 2016, I released Part 3 of this amazing course series, called “Python Network Programming – Part 3: Scapy & Security Tools”, which in my opinion is very interesting and exciting for anyone wanting to enter the world of network security in a 100% hands-on fashion. I am really putting a lot of energy and effort into each of my courses and I am always trying (and succeeding) to pay special attention to the smallest details and provide a lot of value to my students. I really think my courses will get better and better, both by learning from my mistakes and carefully listening to the feedback I get from my students. === So, check out my courses and stay tuned for more!
