While Cisco has shifted focus toward modern virtual-native images like IOSv and IOL (IOS on Linux) packaged within Cisco Modeling Labs (CML), the c7200 Dynamips-based image remains incredibly popular for several key reasons: 1. Bulletproof Stability via Mainline
(even in “high quality”):
Yes, but only if your hardware has sufficient DRAM (minimum 512 MB recommended) and a compatible flash size. The 7200 VXR with NPE-G1 or G2 works well.
