The following steps describe how to create a custom directory, with minimized security settings, for storing GNS3 files.Ĭreate a 'directory folder' and name it 'GNS3-Folders'. It can be used as is or with modifications. I have also pasted the default baseconfig.txt that I use, at the end of this document. Copy this file to the directory 'C:GNS3-FoldersIOS' that is created in the next step. This file path and name will be specified in 'GNS3 - Edit - IOS images and hypervisors - base config. This is the default configuration that is applied to each router as it boots initially.Ĭ. Normally it is located in the parent GNS3 installation folder.ī. Very useful: - After installation, locate the file named 'baseconfig.txt'Ī.
It is a known fact that 2600 series images are not stable with GNS3.One of the most incompatible and crash prone IOS image is of 2611XM series router.GNS3 crashes if the IOS image used is not compatible.Cisco 3725 Router 3700 Series - For MPLSĬ.bin - For SLA.Cisco 2691 Router 2600 Series - Extremely stableĬ2691-adventerprisek9_7.bin.I have some of them as I own the routers.

I faced several problems with GNS3 initially.ģ.
This is the configuration that works for me.Ģ. This document describes in detail, stable configuration details for GNS3 emulator. Since GNS3 is a dump software, you must have good understanding of the Cisco routers and switches series, their IOS images, and how to configure the routers.
