| Problem | Likely Cause | Solution | |---------|--------------|----------| | Router boots only to ROMmon | Bad image or insufficient DRAM | Upgrade RAM; verify checksum of image | | BGP won't establish | TCP mss mismatch | ip tcp adjust-mss 1440 on interface | | Crypto commands missing | Non-k9 image loaded | Check show version – look for k9 | | High CPU in GNS3 | Incorrect idle-pc | Use idlepc get in GNS3 console | | %SYS-2-MALLOCFAIL | Memory fragmentation | Add memory-size iomem 25 and reload |

If you attempt to load this image on a router with less than 128 MB of DRAM, you will encounter a %SYS-2-MALLOCFAIL error during boot. C2691-advipservicesk9-mz.124-17.image

If you are building a home lab for or CCNP studies on a machine with limited RAM, this image is essential . It provides a perfect balance of features and performance that newer, heavier images cannot match for basic routing and switching simulations. | Problem | Likely Cause | Solution |
