It will automatically name the device Etherswitch router, and place into the Switches device category, instead of Routers. On the screen where you’re asked to name the router, select the “This is an Etherswitch router” option (this is important!). Choose Yes, as it will load faster, instead of decompressing every time you start the image: You’ll be asked if you’d like to decompress this image. Select New Image, and click Browse to locate the image in your filesystem (you must supply your own!). (You can also run this image via the GNS3 VM) Pick run this IOS image via the local computer, and click Next >: This example will use a c3725 router IOS image, but the same steps apply if using the other three platforms listed above.įirst, click Edit->Preferences->IOS Routers->New in the GNS3 GUI. Refer to the switching section of this document to see what features will be unavailable to you. This is a rather simple process, but be aware that your options for configuring Cisco switching while using a c3640, c3660, c3725, and c3745 for this are quite limited. Using a c3725 as an “Etherswitch Router” You can also use switches from other vendors such as Cumulus, Extreme Networks and many more. Use it only for basic operations Open vSwitch īy leveraging GNS3 support for Docker, you can now add Open vSwitch to your GNS3 topologies. It’s not running a switch OS, everything is emulated from scratch. While an Etherswitch module does not support advanced layer 2 features, it does allow you to configure basic VLANs, Spanning Tree and other options. This is the official Cisco way of emulating a switch. With a Cisco VIRL IOSvL2 image, you can configure and test a wide range of advanced switching features. Recommended_switching_platform Cisco VIRL IOSvL2 Your selection of image and platform will affect what is possible. While this was true in the past, GNS3 now supports options such as:Ĭomplimentary campus technologies such as HSRP are also supported.

You will now find that you can get to the internet from the virtual machine. (note that you use the interface name, (inside,outside0 not g1/0, etc) (Very different from IOS) You create an object and assign properties to it. Route outside 0 0 192.168.254.2 (The default router on this network) Note that the higher the security number, the more trusted the interface. (Note: Interfaces must be named using the nameif command, and if you use the inside and outside nomenclature, the security levels will automatically be set) Step 2 Configure the outside and inside interfaces: You have an internal network: 192.168.1.0, and an external network: 192.168.254.0, gateway 192.168.254.2Īlthough the external network is on a non routed network, it could be a public IP, but it is set up within a network.Ĭreate a new GNS3 project, and add a switch, a virtualbox VM, a cloud, and ASA, as in this diagram: (note, the switch is only there because you can’t connect anything directly to the cloud interface.) The first basic configuration: Dynamic (many internal hosts to a single or range of external addresses) Once you have your ASA, drag and drop it in to your workspace. Instructions here:Īnd here, while it lasts, with file downloads:

The first step is to create the ASA, which is created in QEMU. Setting up a test configuration on GNS3 with an ASA firewall is possible.
