To prevent your computer from overheating or freezing, you must calculate an . When configuring the image in GNS3, click the "Idle-PC finder" button. GNS3 will analyze the running image and apply a hex code (e.g., 0x60ba1234 ). This tells the simulator to put the emulated CPU to sleep when the IOS is doing nothing, reducing your host computer's CPU utilization from 100% down to less than 5% per router.
