When you are using GNS3 on Win 7/8 and if you stop the router, you get a blue screen saying your PC ran into some problem with the following error:
Your PC will restart after this error :(
After doing some research on the GNS3 forum and reading the users experience, I found 2 solutions to this problem:
1. Run GNS3 on a LINUX Distro e.g DEBIAN or UBUNTU (FYI: A Linux Distro is always more stable than Windows)
2.If you are not comfortable with LINUX then you can still use WINDOWS but make sure you run the following CISCO IOS Images according to a post (please see extract below) on the CISCO LEARNING NETWORK by Navneet.Gaur :
“These are the stable working IOS images for GNS 3.I have some of them as I own the routers.1Cisco 2691 Router | 2600 Series - Extremely stablec2691-adventerprisek9_ivs-mz.124-9.T7.bin2Cisco 3640 Router | 3600 Seriesc3640-ik9o3s-mz.124-25.bin3Cisco 3725 Router | 3700 Series - For MPLSc3725-adventerprisek9-mz.124-15.T5.bin4Cisco 7200 Router - Extremely stablec7200-advipservicesk9-mz.124-2.T.binc7200-advipservicesk9-mz.150-1.M.bin - For SLA”
I don’t promise that your PC will not crash but you can still try.
I tried the “c2691-adventerprisek9-mz.124-5a.bin” image…its really stable on Windows 8.
I can start and stop the router..No BSOD so far J
1 tip when using GNS3: After you have started your router on GNS3, right click on it and calculate a new idle-pc value. You will be presented with a list of values choose the one starting with an asterix (*)
Hope this helps you in preparing for your Cisco CCNP Exams..Good Luck !!!
