This appendix lists the Cisco hardware that’s supported by Dynamips and GNS3. Dynamips only emulates Cisco routers that use MIPS architecture and does not support all Cisco models. After the list of supported routers, you’ll find a list of recommended IOS image files that GNS3 can automatically apply the correct Idle-PC values to, without performing an Idle-PC calculation.
In GNS3, you can emulate Cisco routers from five different series (1700, 2600, 3600, 3700, and 7200), with varying degrees of feature support.
The following routers are no longer getting IOS updates from Cisco. The IOS filenames listed here are the recommended versions for GNS3, though older versions should work fine.
The Cisco c7200 series router continues to receive IOS updates from Cisco and supports version 15.x of IOS.
