*Mar 1 00:03:42.663: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up Let’s look at the interfaces of R1:Įnter configuration commands, one per line. 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). This powers on all devices in the Workspace, as well as launches Solar-Putty and creates tabs for each device:
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: Cisco/HuaWei/Juniper routers and some router simulators like GNS3) bgp. To create a new GNS3 topology, select a group of devices in the Devices Toolbar by clicking the device type button. This repository contains three docker images: i) An ExaBGP router with Socket.
#CISCO ROUTER IMAGES FOR GNS3 HOW TO#
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.
