Easy GNS3 Install

one of the major issues that a lot of people have encountered with gns3 in the past is the complexity of setting up the gns3 vm and the gns3 gui and making that work together properly there's been lots of issues especially on windows if you're using vmware workstation player a lot of people have had a lot of issues in this video i'm going to show you how you can get gns3 up and working very very quickly we're going to get gns3 working on a windows 10 computer in a few minutes okay so let's see how long it takes me to get vmware workstation player downloaded and installed import the gns3 vm and get a gns3 network up and running now in this example i'm doing everything on this windows 10 laptop i'm controlling it from my mac that just makes it easier to do the recordings but all the configuration and installation is going to be done on this windows 10 laptop the first thing you need to do is go to gns3.com and then click free download i'm not going to download the gns3 gui for windows mac or linux i'm simply going to download the gns3 vm and in my example i'm going to download the gns3 vm for vmware workstation and fusion i'm going to click save to download that to my local computer it's about 500 meg all you need to do now is wait for that to download but while that's downloading let's go to vmware.com and what we're going to download here is vmware workstation player this is free software from vmware now at the time of this recording they still showing 15.5 here but 16 has actually been released so when i click on the download now link notice the version that i'm downloading is 16.0 so i'm downloading vmware workstation player that's a hypervisor that allows me to host the gns3 vm on my windows computer and i'm downloading the gns3 vm that's all i'm gonna download okay so vmware player has downloaded i'm still waiting for the geno3 vm to download but what i'm going to do is show in folder and i'm going to double click the vmware player executable to install the software and click yes to allow the app to make changes to my device the vmware workstation player 16 wizard starts i'm going to click next i'm going to agree to the license agreement and click next and i'm going to click next again i'm not going to join the customer experience program i'm going to click next click next again and click install now one thing the software will do is it will add additional network adapters to your computer so under my network adapters at the moment i don't see vmware workstation adapters but as the software installs you'll notice adapters get installed and there's one and here's another so it's normal behavior for vmware to install additional adapters okay installation has completed i'll click finish so first step is completed install vmware workstation now we can import the gns3 vm into vmware workstation so the gns3 vm has successfully downloaded i'll show that in folder and what i'm going to do is extract this zip file file has been extracted so under downloads i've now got gns3 vm vmware workstation and there's an ova so what i'll do is start up vmware workstation player i'm going to use it for free for non-commercial use you can enter a license agreement if you want to use it for commercial reasons but i'm not going to do that i'm going to click continue and click finish now i need to go to player file open i'm going to go to my downloads directory open the workstation directory and open the ova and click import to import the gns3 vm you just need to wait for that import to complete once it's imported you can edit the virtual machine settings as an example you may want to allocate more ram you may want to allocate more cpus for the moment i'm going to leave everything at default but if you want to run larger topologies you're going to need to increase these values so add more memory as an example or add more processes you also want to make sure that you've got virtualized intel vtx enabled or amd v enabled i'm going to click ok and i'm going to click play a virtual machine virtual machine is now booting up as you can see the gns3 vm has booted very important we want to see kvm support available is true you're going to want to have vtx enabled in the bios of your computer you're going to want to have wsl version 2 disabled or hyper-v disabled if you're using this within vmware workstation player okay so we're told that we can launch the web ui and go to 192.168.52.128. that's the gns3 web ui so i'm going to open up a web browser in this case chrome and i'm going to browse to 192 168 52 128 and as you can see a web ui is displayed now if i go to player manage virtual machine settings network adapter notice it's set to host only and the second adapter is set to nat rather than using nat you may want to use bridged so that you can connect to the devices in your virtual machine remotely i'll cover that in a separate video what i'm going to do here is add a blank project and let's call it gns3 project 1. you probably want to use a better name than that but that'll get us started as you can see now i've got a web ui running on my laptop connecting to the gns3 vm and what i can do now is click add a node and i'll drag two vpcs devices into my topology and i'll drag a ethernet switch into my topology what i can do is click on them and drag them around i'll click on add link click on the pc and then connect the ethernet link click on the switch again take the second ethernet port and connect it to the second pc click on this little arrow and start all nodes in my topology i'll minimize that right click on the vpcs device open up a web console you can see a web console has started what i'll do now is move these devices up so we've got more space and then i'll right click open web console and as you can see i've got a web console to pc1 i can move this around and i could make it smaller so i'll make it a bit smaller right click on pc2 open up web console there's pc2 on pc1 click here and let's give it an ip address of 10 1 1 with a mask of that on pc2 ip address 10 112 mask like that back on pc1 let's ping 10.1.1.2 and notice i can ping from pc 1 to pc2 back on pc2 can i ping pc1 and the answer is yes i can now you can make your topology look more pretty but there you go i've got a gns3 topology up and running i'm running this within the gns3 vm within vmware workstation player on my windows 10 laptop okay so let's make this a little bit more pretty i'm going to right click and go to change symbol and i'm going to look for a host symbol so let's say this one and click apply right click here change symbol i'll change it to host and click apply on the switch right click change symbol and i'll search for switch and select that switch symbol and click apply and there you go i've got a nicer topology with two vpcs devices and a switch and they can ping each other okay but now you may want to add other devices to your topology so you might want to add a vendor switch like cumulus or cisco or rooster to your topology now to add other vendor devices click on the gns3 icon and go to new template i'm going to leave the default install new appliance from the gns3 server click next and here you can search for different vendors such as cumulus vx or ios v i'm going to select cisco ios v layer 2 and click install various images are shown here i can't provide you with images you need to provide your own image so get that from the vendors website in my example i've got this ios v image over here which is the one that's listed here if you don't have the image click download and that's going to take you to the vendors website so in this example to cisco's website where you can log in and download an image so you'll have to download the image yourself if you click on the download button it'll take you to the relevant vendors website in my example i'm going to click import and i'm going to select the image that i've downloaded i'm told that the image has been imported successfully i can see a little tick here so i'm going to click create and use the default name and click add template that means that my node has been added to gns3 and i can use it it's using the default image here but you can change that by clicking on gns3 go to preferences in my example this is a qmu image so i'm going to select that and then i'm going to select cisco ios v layer 2 go to general settings and what i can do now is change the symbol i'll search for switch this is a layer 3 switch so i'll select that icon click choose symbol and click save and then i'll go back to my project click add node and what i can do now is drag that cisco ios v switch into the topology and i'll drag another one so what i've got now are two cisco ios v switches i can now connect them via various interfaces so i'll connect the two switches via the gigabit zero zero interfaces and start the switches up so right click start right click web console and as you can see now the first switch is booting up i'll minimize that open up another web console and you can see the second switch is now booting up that's how simple it is these days to get gns3 up and running and add devices to your network i could as an example add a vpcs device to the network once again so add that here so add these two devices to my cisco network something like that again you can change the symbols of these devices if you don't like the way they look you could change the template if you wanted to but in my example i've just changed the individual devices going back to my switches i can see that the two switches are booting up now i don't have a lot of ram and cpu on this gns3 vm if you're going to run cisco devices you're probably going to want to change your virtual machine settings and allocate more ram and cpu to your virtual machine i've only got two gig of ram in this virtual machine so these two devices are taking their time booting up they're running quite slow you probably want to allocate more ram than what i've got here but as an example i could give the first switch a name let's say switch one switch to change the name to switch to go on to interface vlan 1 no shut it and this is switch 2 so i'll give it an ip address of 10 1 one two five two in this example on switch one interface vlan one no shut it ip address 10.1.1.251 24 mask and hopefully this switch will be able to ping the second switch and there you go so switch one can ping switch two and switch to campaign switch one okay so i've now shown you how to build multiple topologies in gns3 doing everything through a browser i'm not using the gns3 gui here all i'm using is the gns3 vm and i'm connecting to that through a browser i'm doing everything through the browser as an example i could right click on my switch and open that in a new tab and notice i've got a separate tab for my switch i'm doing everything through a browser okay so gns3 have made a lot of improvements to their web ui they still working on this and improving the web ui but it's a lot better than it was in the past and you don't have to use the gui application if you don't want to this makes it a lot easier to host the vm on an esxi server or host it in the cloud as an example and i'll cover that in separate videos i'm david bumble i want to wish you all the very best you
