GNS3 2.1 Install and configuration on Windows 10 (Part 1): Components and software requirements
 
03:33
This video explains and demonstrates how to install the GNS3 Windows GUI on a Windows 10 PC. This is one of a series of videos showing you how to get started using GNS3 on Windows. Transcription: This is one of multiple videos showing you how to download, install and configure GNS3 version 2.1 on a Windows 10 PC. When you first start out with GNS3 it can be quite confusing and even overwhelming to know what to do because there are many components and technologies that you can leverage within GNS3. In brief, there are two main components that you need to be aware of. The first component is the GNS3 GUI or GNS3 Graphical User Interface. This is a Windows executable that you install on your Windows computer. The second main component is the GNS3 VM or GNS3 Virtual Machine. This is a Virtual Machine that you run within a hypervisor such as a VirtualBox VMware Workstation or VMware Player. In some cases, you don't have to use the GNS3 VM. You only need the GNS3 Graphical User Interface. But for most implementations and for the best use of GNS3, it's recommended that you use both the GNS3 GUI as well as the GNS3 VM. In addition,you're going to need the operating systems of devices. So in other words, if you want to run a Cisco IOS router, you need the Cisco IOS software. If you're going to run an Arista switch, you need the Arista operating system or if you want to run a Juniper firewall, you'll need the Juniper operating system. So whenever you want to add networking vendors device to your GNS3 topologies, you'll need to provide the operating system for that device and you'll need to download the operating system from the vendor's website or as an example, copy it from a physical router or switch. And neither I and nor GNS3 can legally provide you with a Cisco IOS images. You have to provide your own images. that is a requirement for using GNS3. I would love to give you IOS images but neither I or GNS3, due to legal requirements, are able to provide IOS images to you, you need to provide your own. In these series of videos I'm going to show you firstly, how to install the GNS3 GUI and get a basic network working using the GNS3 GUI. And then in subsequent videos I'll show you how to download and integrate the GNS3 VM with the GNS3 GUI and how to run devices such as Cisco VIRL IOSv and IOSv Layer 2 on the GNS VM.

In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. In this video we program a Cisco IOSv router using Python on an Ubuntu Docker container. The script used in this video is available on GitHub here: https://github.com/davidbombal/pythonvideos/blob/master/pythonR1script1.py Transcription: This is one of multiple videos discussing Python programming. Now there's a lot of information on the internet with regards to Python programming, but in these series of videos I'm going to concentrate solely on the use of Python with networking devices and specifically with gns3 . I'm a very strong believer in practical learning. Think about it, when you were a child, did you go to university or school to learn how to ride a bike? Typically you learnt how to ride a bike by riding a bike and falling off a few times, making mistakes. But as you practiced you got better and better at riding a bike. I think the same is true for any other skill that you want to gain and any other knowledge that you want to obtain. The best way to do it is to just do it , make mistakes, pick yourself up and try again. And with that in mind I'm going to show you how quickly you can get programming a Cisco network using Python. In Google I've done a search for Python telnet and my first hitch is the telnet library or telnet client available in Python 2.7. Now there's a large debate in Python community about which version of Python you should learn. Python 2.7 is being replaced by Python 3. But notice on the Python website you can still download Python 2.7 and a lot of operating systems and network devices have version 2.7 by default. I'm going to show you both Python 2.7 and python 3 as part of these videos or as part of my GNS3 Python course. You may only have Python 2.7 available so it's good to know that but you should also learn Python 3 for the future. So notice the simple script that we can copy from the Python documentation. We'll start off with a script and start programming our GNS3 topology. In GNS3, I'm going to drag a iOS router to the workspace as well as an iOSv switch. These devices take a while to boot up, so to allow my docker containers to connect to the Internet quickly, I'm going to use a layer 2 switch. One of the docker containers available is in a blue 2 container and that's what I'm going to use in this topology rather than trying to get python running on your Windows PC or trying to get Python working on other operating systems. It's going to be a lot quicker for us just to use a docker container and add that to our GNS3 topology. Again, my belief is start or learning as quickly as you can, make mistakes and learn from that. Don't get hung up with trying to learn the best way to do everything right away. Just get started. Some people believe that they need to have a degree to become a programmer or use programming skills in networking. I don't necessarily agree with that. Just get started. So on the Ubuntu machine I'm going to edit to the config. I'm going to set this device to use DHCP and click Save and click start. To boot up the network, I'm going to open up a console to each device. Now again the Cisco devices will take a while to boot up but our docker container has already booted up and we can already ping google.com even though the switch and the router are still booting. So how to get update? We will get update our references in ubuntu, that's done, will install Python. In this first example I'm going to install Python 2.7. So Python version of Python that we're using is 2.7. 1. So here is the script that we're going to start off with it's not perfect. What we will be doing now is not necessarily the most optimized way of implementing a script like this but the idea there is, we want to get started, get it working by for instance creating a loop back on the router and configuring VLANs on the switch and then we can build on our script and optimize it. I'm going to use nano to create a file so let's call this python Router1 script 1 to start off with. And then I'm going to paste the code off the internet into nano. so we’re importing modules here get passes telnet library. The device that we're going to telnet to is going to be the router. So we need to configure the router's IP address, username and password and other details for when the script telnets to the router. So before we continue with our script let's configure the network devices. See here's the router it's booted up. Now I'll bypass the initial configuration dialog. Transcription limited by YouTube.

GNS3 Talks: Use the NAT node to connect GNS3 to the Internet easily!
 
09:10
Starting with GNS3 2.0 a NAT node is available. This node allows you to a connect a GNS3 topology to the Internet via a NAT. But your topology is not accessible from the internet. It’s useful when you need to download stuff from internet (package, licence check…). And it’s easier to use than the Cloud node. The NAT node require the GNS3 VM or a Linux computer with libvirt installed. By default the NAT node run a DHCP server that will give you an IP in the range 192.168.122.0/24.

For much more, go to http://www.cciepython.com Learn how to automate your networks using Python. I want to welcome you to this Python for networking course. This course is not like other Python courses. In my experience I found that a lot of Python courses are trying to make networking engineers Python developers. They concentrate very heavily on Python theory and they spend a lot of time teaching you the ins and outs of Python instead of getting you to use Python to configure network devices as quickly as possible. That’s what I’m going to do in this course. This course consists of multiple portions and leverages GNS3 to create multiple network topologies that you can configure and automate through Python. In the next video I am going to show you how you can very quickly start configuring network devices using Python. One of the biggest stumbling blocks when learning network automation is the barrier or huge mountain that Network Engineers think they have to climb before they can configure network devices. That’s not true. Within 20 minutes in the next video, I’ll show you how you can configure OSPF and loopback interfaces on a Cisco IOSv router. The video after that will show you how to configure VLANs and you’ll learn how to configure Cisco network devices using telnet as well as SSH. In the upcoming videos, we’ll use multiple modules and leverage the work done by others. Don’t reinvent the wheel, leverage the hard work that others have done and made freely available through Python. We’ll use tools such as the telnet library, Paramiko, Netmiko, NAPALM and other s to automate the configuration of the multiple networks. Again, I’m leveraging GNS3, in most of these videos you don’t have to use GNS3. You could use real world physical equipment if you wanted to. The advantage however of GNS3 is that, you can build virtual networks very quickly on your laptop. You can learn Python and configure Python networks wherever you are. You just need your laptop and GNS3 running on your laptop. It’s also a safe place to be. Your GNS3 network is not your live network. So you won’t inadvertently break a production network by running a Python script on your GNS3 network. It’s a safe place to learn. Once I’ve shown you how to quickly configure networks using Python, there is a theory section. I’m going to take you from the basics of Python to more complex topics. So if you want to take your Python knowledge further, and learn the ins and outs of Python, the Theory Section will give you that knowledge. And then there’s a section providing more complex topologies, more complex scripts and scripts using a software developer approach to writing code. As a saying goes, Rome wasn’t built in a day; Babies don’t run marathons. And in the same way, don’t try and conquer the world of Python in one day. Learn the basics, make mistakes, try again and constantly increase your knowledge. So again, welcome to my Python course! Please provide feedback. Based on the feedback and suggestions I receive, I’ll add more content or just the content. Don’t forget to subscribe to my YouTube channel. I’m always posting new content to my YouTube channel. So if you got suggestions of content to add to this course, or just other general content that you would like to see, let me know and I’ll either add it to this course or add it to my YouTube channel. I want to wish you all the very best in your journeys in Network Programmability and Network Automation. It’s the future and the future is here for you to grab it and change your future to improve your job prospects and ensure that you don’t become a relic of the common line interface. The world is changing and we need to keep on learning to improve our skill set and take hold of bigger opportunities in the industry. With that said, I want to wish you all the very best in your journeys with Python, Network Programmability and Network Automation.

GNS3 Talks: AAA Docker Appliance: Easy TACACS & RADIUS GNS3 servers! Part 1
 
08:41
GNS3 now has a AAA Docker Container. This makes it really easy to add RADIUS and TACACS servers to your GNS3 topologies! For lots more content, visit http://www.davidbombal.com - learn about GNS3, CCNA, Packet Tracer, Python, Ansible and much, much more. Two prominent security protocols used to control access into networks are Cisco TACACS+ and RADIUS. The RADIUS specification is described in RFC 2865 leavingcisco.com, which obsoletes RFC 2138 leavingcisco.com. Cisco is committed to supporting both protocols with the best of class offerings. It is not the intention of Cisco to compete with RADIUS or influence users to use TACACS+. You should choose the solution that best meets your needs. This document discusses the differences between TACACS+ and RADIUS, so that you can make an informed choice. Cisco has supported the RADIUS protocol since Cisco IOS® Software Release 11.1 in February 1996. Cisco continues to enhance the RADIUS Client with new features and capabilities, supporting RADIUS as a standard. Cisco seriously evaluated RADIUS as a security protocol before it developed TACACS+. Many features were included in the TACACS+ protocol to meet the needs of the growing security market. The protocol was designed to scale as networks grow, and to adapt to new security technology as the market matures. The underlying architecture of the TACACS+ protocol complements the independent authentication, authorization, and accounting (AAA) architecture. RADIUS uses UDP while TACACS+ uses TCP. TCP offers several advantages over UDP. TCP offers a connection-oriented transport, while UDP offers best-effort delivery. RADIUS requires additional programmable variables such as re-transmit attempts and time-outs to compensate for best-effort transport, but it lacks the level of built-in support that a TCP transport offers: TCP usage provides a separate acknowledgment that a request has been received, within (approximately) a network round-trip time (RTT), regardless of how loaded and slow the backend authentication mechanism (a TCP acknowledgment) might be. TCP provides immediate indication of a crashed, or not running, server by a reset (RST). You can determine when a server crashes and returns to service if you use long-lived TCP connections. UDP cannot tell the difference between a server that is down, a slow server, and a non-existent server. Using TCP keepalives, server crashes can be detected out-of-band with actual requests. Connections to multiple servers can be maintained simultaneously, and you only need to send messages to the ones that are known to be up and running. TCP is more scalable and adapts to growing, as well as congested, networks.

For lots more content, visit http://www.davidbombal.com - learn about GNS3, CCNA, Packet Tracer, Python, Ansible and much, much more. 300-101 ROUTE Exam information: https://bit.ly/2GkcFXQ 300-115 SWITCH Exam information: https://bit.ly/2KrSWIe 300-135 TSHOOT Exam information: https://bit.ly/2IlHpgY Training: http://www.davidbombal.com Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.[1] The protocol is classified as a path vector protocol.[2] The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions. BGP may be used for routing within an autonomous system. In this application it is referred to as Interior Border Gateway Protocol, Internal BGP, or iBGP. In contrast, the Internet application of the protocol may be referred to as Exterior Border Gateway Protocol, External BGP, or eBGP. BGP neighbors, called peers, are established by manual configuration between routers to create a TCP session on port 179. A BGP speaker sends 19-byte keep-alive messages every 60 seconds[5] to maintain the connection.[6] Among routing protocols, BGP is unique in using TCP as its transport protocol. When BGP runs between two peers in the same autonomous system (AS), it is referred to as Internal BGP (iBGP or Interior Border Gateway Protocol). When it runs between different autonomous systems, it is called External BGP (eBGP or Exterior Border Gateway Protocol). Routers on the boundary of one AS exchanging information with another AS are called border or edge routers or simply eBGP peers and are typically connected directly, while iBGP peers can be interconnected through other intermediate routers. Other deployment topologies are also possible, such as running eBGP peering inside a VPN tunnel, allowing two remote sites to exchange routing information in a secure and isolated manner. The main difference between iBGP and eBGP peering is in the way routes that were received from one peer are propagated to other peers. For instance, new routes learned from an eBGP peer are typically redistributed to all iBGP peers as well as all other eBGP peers (if transit mode is enabled on the router). However, if new routes are learned on an iBGP peering, then they are re-advertised only to all eBGP peers. These route-propagation rules effectively require that all iBGP peers inside an AS are interconnected in a full mesh. How routes are propagated can be controlled in detail via the route-maps mechanism. This mechanism consists of a set of rules. Each rule describes, for routes matching some given criteria, what action should be taken. The action could be to drop the route, or it could be to modify some attributes of the route before inserting it in the routing table.

FREE download: http://bit.ly/solarputty The wait is over! Professional grade CLI access is now free, including: - Tabs - Native GNS3 integration - Login scripts - Modular credential repository - Combined search and quick connect - SSH, Telnet, SCP, and SFTP support - Windows search integration Key Features - Manage multiple sessions from one console with a tabbed interface - Save credentials or private keys to any session for easy login - Automate all scripts you’re using when connection is established - Find your saved session easily thanks to Windows Search integration - No installation is needed Tabs: Use the credentials tab to store your most commonly used credentials. When you create a new session, reference that stored credential rather than typing it out again. Update all session credentials by updating the stored credential. Search or Quick Connect: Did you notice the field you use to search for a saved session can also be used to quick connect? Try entering an IP and port, like 10.199.4.12:22 and pressing enter. Colors: Colors can be used to remind you which sessions go to production gear, which data center your connected to, or anything else you like. Set the color when creating a new session or editing an existing session. Key shortcuts: Keep your hands on the keyboard because mice are slow! Ctrl + t: Open a new tab Ctrl + w: Close tab Alt+F4: Exit Solar-PuTTY Scripts - Automated login, bulk configuration: Scripts are executed immediately after login. You can use scripts to automatically enter enable/privileged exec. You can also create longer scripts to make configuration changes to a device and then run the script on several sessions. Just like credentials, these are stored and can be referenced by any session. Session - Export and import: Whether you’re in a classroom or in the office it’s a pain to share connection information verbally. Instead, use the three dots in the top left of Solar-PuTTY to export your sessions and have your pal import them. Less talk, more results. Tags - Better than folders: Tags are a great way to organize your sessions without having to worry about hierarchy or overlap. We like to use them for location (“Dallas Datacenter”) and roles (“Border Router”), but you can use them for anything you like. Create tags in Settings (Ctrl + s). Apply tags to any sessions. Tags are searchable! Session Logging - Know your work: Dreaming of a CCIE? Review your logs after a lab and assess opportunities where you can improve in terms of accuracy, speed, order of operations; all important for the CCIE. Bad outage caused by a config? Prove exactly what you did or did not do. Better yet, prove how you fixed it! Session logging can be enabled when you create a new session or by editing an existing session.

In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. In this video we program a Cisco IOSvL2 switch with VLANs by using Python on an Ubuntu Docker container. Script used in this video is available on GitHub here: https://github.com/davidbombal/pythonvideos/blob/master/pythonS1script1.py This is one of multiple videos teaching you network programmability using Python and GNS3. might take on the learning programming or any other technology is to just do it,try it make mistakes, pick yourself up and try again. Don't try and do it perfectly on the first run. Create some code and then iterate or improve and refine your code as you go along. GNS3 makes this process very easy. In the previous video, I configured the router using a Python script. This is what our Python script looks like. We programmatically configured the loopback addresses and OSPF on the Cisco IOS of the router. Now let's configure the switch. The router was given this IP address through DHCP. What I'll do is configure the switch manually on the SVI so IP address question mark. We have to specify the IP address here,so we'll use 72. So hostname switch1. We need to configure login details, so I'll set an enable password a Cisco,I'll set up a username of David, With a password of Cisco and on the vty lines, I'm going to use the command log in local and transport input all. So let's manually test that telnet works a telnet to the IP address of the switch. Log in with our username of David, password of cisco enable put password in, we can login, so we've proven that telnet works on the switch. On the switch at the moment, show VLAN brief shows us that only the default VLANs are configured. Now previously we configured this Python script. What I'm going to do now is copy this Python script to another script called pythonS1script1 As I said in the previous video, we are not trying to do everything perfectly here we are trying to get started and we'll iterate and improve as we go along. So let's use an nano to edit that script. In this case the IP address of the switch is 192.168.122.72 We'll be prompted for our username and our password. We're going to telnet to that host. we are looking for a username and password prompt. So let's confirm that that's what we're going to see. We are prompted for a username so that's correct. We're prompted for a password so that's correct. So the script will correctly look for and then enter those values. We're going to send the enable command to the switch enter a password of cisco, then type conft and we'll configure a VLAN of 2. Now you can as always refine this and improve it but I'm going to type exit and then create VLAN 3 and then exit and let's get rid of all of this. So let's control K that control U, paste it back control K, control U, control U. Now you could if you preferred just do this copy that and paste it in. So this creates VLANs 2, 3, 4, 5 6 control X, save the configuration. Now again before I run the script, notice we only have the default VLANs configured and what I'll do now is type pythonS1script1 user name is David password is cisco. This is what was configured on the switch. We can see in the output of the switch that it was configured via telnet show VLAN. Notice the VLANs have been added to the VLAN database. VLAN 2, 3, 4, 5, 6 have been added it was as simple as that to use Python to configure a network switch. Now what we could do here is an example is set a description. So Python VLAN2 as an example control X save the script, run it again and hopefully what we should see in the output here show VLAN. What's nice about the output of the script is we see that there's a problem I used the wrong command. So first manually test command is not supported so manually test and then automate. So let's do that again. The description is actually the name command save that, run the script again. I didn't configure that manually it was configured by the scripts to show VLAN, notice the name has changed. So let's do that for the other VLANs, control K, control U, control U, control U, control U, control U. This is one of the reasons why you want to use variables and the loops because it saves a lot of time doing this manually but we'll leave that for a different script. So python pythonS1script1 user name is david, password is cisco. We see what was configured and if we type show VLAN we can see the configuration on the switch. This is the script that we created.

This course is not like other CCNA courses. This course is practical, it’s hands-on and it allows you to practically verify your knowledge of CCNA topics. Before we get started, let me ask you a question: Are you ready to take and pass your CCNA exam? Are you sure that you are prepared for the exam? Well, this course can give you both the confidence and the knowledge to pass the CCNA exam. In my experience I found that a lot of CCNA courses are very theoretical. They teach you theory but they miss the practical component of hands-on labs. The best way that you can learn Cisco CCNA technologies is to simply do it. Configure devices, troubleshoot devices and spend time configuring networks…….. Practical hands-on labs are simply the best way to learn networking and specifically Cisco technologies in preparation for the CCNA exam. This course will as quickly as possible get you configuring Cisco networks. There are many network topologies in this course that allow you to verify your knowledge of networking technologies such as BGP, OSPF, EIGRP, Spanning Tree, VLANs, HSRP and many other technologies that you need to know for the CCNA exam. When you were a child, you didn’t learn to ride a bicycle by reading a book. You learned to ride a bicycle by riding a bicycle, you may have fallen off a few times but through practice, you become proficient at riding a bicycle. In the same way in this course, you’re presented with multiple practical labs that you need to complete. This is hands-on training you’ll be presented with a lab scenario which you can either complete yourself or you can watch me complete the lab and learn various tips and tricks along the way. I’m not simply going to complete the lab, I’m going to explain things as I completed. This is a comprehensive course that ensures that you are ready to take the CCNA exam, make sure that you are prepared for the lab portion of the CCNA exam by taking this course. I’’m David Bombal and I’ve been training Cisco courses for over 15 years. I passed my Cisco CCIE certification exam in 2003. The future is here, are you going to grab it and get a certified as a Cisco Certified Network Associate? You can change your future just like I did when I got my CCNA certification , the CCNA is your first step into the world of networking and a bright future working with Cisco devices and networking technologies. The world runs on networks. Without networks and network engineers to configure, manage and optimize networks, we wouldn’t have Google, we wouldn’t have Facebook, we wouldn’t have internet banking, we wouldn’t have smartphones or any of the other devices and technologies that we take for granted in a modern connected world. We are connected by networks and people like you and I need to manage, troubleshoots and optimize networks to ensure that the world can connect and communicate. So what are you going to do about it? Are you ready to take the next step? I’m ready, what about you? Are you ready to take the next step in ensuring that you are prepared for the CCNA exam? Click on the Buy button and join me in the next video where we start practically configuring and troubleshooting Cisco networks.
