![]() One should thus expect the same behavior observed in this configuration example regardless of the particular hardware and software used for the router and host.įor the next post in this series we’ll use the packet capture tool Wireshark to look at the SLAAC process in more detail. Recall that the auto-addressing functionality of SLAAC is included entirely within the IPv6 protocol standard. ![]() Now from the host, ping the router interface address you assigned:įinally, let’s run a few verification commands on the router: Assuming everything worked you should see a SLAAC-assigned address beginning with the global unicast prefix you assigned on the router interface: On the QEMU or VPCS host make sure ‘ip auto’ is configured (it should be by default) then run the ‘show’ command. The particular prefix is unimportant–just make sure you use a /64 prefix so that SLAAC will function properly. On the Fast Ethernet interface the host is connected to, enable IPv6 and add an IPv6 address from the global unicast range (2000::/3). Start the router then enable IPv6 unicast routing globally. Using GNS3 (covered in the last post), create a simple topology of one router and one host connected via Fast Ethernet: After obtaining the IP, from PCI try pinging PC2 and from PC2 try pinging an external DNS, like 1.1.1.1.Let’s take a look at the auto-addressing functionality built in to IPv6: Stateless Address Autoconfiguration–or SLAAC.Once you have added the host, you can start the VPCS process by selecting the VPCS device, then choosing Device Start (the Device menu can be also accessed by right-clicking on a device). Configure the IP addresses for the switches and the VPCs as they were in the Simple switching exercise. ![]() By dragging one in from the End devices pane. Complete the following steps to create broadcast domains for VLAN 10 and VLAN 20, keeping in mind that in the beginning all ports are in the broadcast domain called VLAN 1: Chapter 8 9 1. Open a console for both VPCS and obtain an IP from the DHCP with the command ip dhcp There are two ways you can run VPCS by far the easiest is to add a VPCS host to your topology.Connect the NAT cloud and the 2 VPCS to the Switch.Create a new project and from the left pane Browse all devices icon drag the NAT Cloud, a switch and 2 VPCS.If you can't see the correct VM name try refershing the settings. In GNS3 VM preferences make sure Enable the GNS3 VM is enabled and the correct Virtualization engine is selected. You can leave the other settings as default unless you have a specific reason to customise them: In order to be sure networking is going to work properly, select Server from the left menu and verify Enable local server is flagged and Host binding: matches your GNS3 VM subnet. In General you can set your own preferences for where to store your projects etc. When you are able to ping the GNS3 VM it's time to open GNS3 and check its Preferences.Īt first execution, allow root permissions for uBridge to interact with network interfaces: If ping does not work check if the vboxnet0 has been assigned the correct network, from the VirtualBox menu -> File -> Host Network Manager.: Try and ping the GNS3 VM IP from macOS terminal. Make sure KVM support available is set to True and take note of the IP in this case 192.168.56.104. Start the GNS3 VM and wait for the boot process to complete. Specifically it lets you configure the IP address, next hop gateway, and a few other parameters of up to 9 virtual PCs, and it lets you run pings and traceroutes. These permissions are needed from the GNS3 application to control the GNS3 VM (start, stop, configure interfaces, cpu, ram, etc.) GNS3 Function: VPCS VPCS is a program that runs within Windows or Linux and implements limited network functionality. ![]() macOS might warn you about permission to monitor files and control the system from your terminal. On the next screen click on import and you should be good to go. For mac users, just double clic GNS3.VM.VirtualBox.2.2.18.zip you just downloaded and a new folder GNS3 VM will be automatically created for you containing the extracted files.įrom VirtualBox UI select Import and browse for the file GNS VM.ovf inside the GNS3 VM folder. Now it's time to extract the GNS3 VM and import it into VirtualBox. Just drag GNS3 into your application folder and it's done: The installation is pretty straightforward. ![]() In this article I will be using VirtualBox, so fell free to download and install it as well if you'd like to follow along. If you don't have an account, you will have to create one!įor optimal performance, also download the GNS3 VM. Head over to GNS3 software page and download macOS version 2.2.18. We will focus on these specific version, GAs at the time of writing but hopefully the same instructions might be applicable for slightly different versions: In this article, I'll show you how to install and configure GNS3 on a Mac Catalina. ![]()
