![]() ![]() In the new GNS3 1.4, there is a way to run a second category of switches and routers. ![]() For older images, we use and maintain Dynamips an emulator dedicated to emulate some Cisco hardware. GNS3 offers multiple ways to emulate IOS. This Image was tested with Gns3 1.1 and i hope this will also work fine with the latest GNS3 version as well. Following are the details and recommended setting of Gns3 3745 IOS image for your GNS3 setup. If you need the IOS for your real hardware then it is better to Contact Cisco for the latest and best IOS for your device. ![]() Remember this IOS is only for informational, practice purposes, and for GNS3 used. (adsbygoogle = window.adsbygoogle || ).push() From here you can download the Cisco 3745 IOS image for your GNS3 and perform different GNS3 labs with this IOS. learn more about Layer 3 Switching vs Routing In this way you will be able to perform different switching labs with GNS3 like Vlans, inter-VLAN (Router on a stick), VTP (VLAN trunking protocol), different multi-layer functionality, etc. You can use the NM-16ESW module with this 3745 IOS, which will enable the switching functionality in GNS3. If you are a beginner then learn more here:Cisco Switch Basic Configuration, how to use or configure GNS3Ĭisco 3700 Series are the multi-service routers that provide LAN/WAN connectivity, new high-density service modules, and support for multiple advanced integration modules. Gns3 is one of the famous network simulators and its hot feature is that it can run the real Cisco IOS image, as compared to another network simulator like packet-tracer which performs all functions based on programming. IOS images support different packages like routing, switching, and inter-networking, etc. IOS image is software or Operating System used in most Cisco routers and switches. Since these are IOS images, they will act like real routers, as you’ll see.Īfter R1 loads up, we’ll already be at the enable prompt, due to the configuration files GNS3 includes (they also configure “logging sync” and “exec-time 0 0” on line con 0 for us, and let us bypass that initial configuration dialog).Cisco Router 3700 Ios Image Download For Gns3 This powers on all devices in the Workspace, as well as launches Solar-Putty and creates tabs for each device: Click the Interface Names icon (this is optional), to display the interfaces on each device, that have been connected together.īelow, the green Start button (marked #1) and the Console button (marked #2) have been selected.Left click FastEthernet0/0 of R1, and connect it to FastEthernet0/0 of R2.In this example we’ll use FastEthernet0/0 of each router to connect them together: Click on a device in your topology to display available interfaces.The mouse cursor will change to indicate that links can be added: Click the Add a Link button to start adding links to your topology.Click the Toolbar Device button again (or the X in the corner of it) to collapse the group:.Drag and drop the node again into the GNS3 Workspace, which will result in routers R1 and R2 appearing in both the Workspace, and the Topology Summary:.In this example a router is now available: An instance of the node becomes available in the Workspace. Drag and drop the selected node (device) to the GNS3 Workspace.In this example, a c3725 IOS image has already been imported, so we’ll use it.In this example the Routers group was selected: To create a new GNS3 topology, select a group of devices in the Devices Toolbar by clicking the device type button.If not, please refer to other guides which explain how to download, install and configure GNS3. This document assumes that you already have GNS3 installed and a Cisco IOS router image added to GNS3.
