Technically, the image is not without flaws when used in emulators. The 3745’s CPU architecture and the lack of precise timing in Dynamips can cause issues with real-time protocols (e.g., HSRP timers, VoIP) and can consume significant host CPU cycles despite its age. Furthermore, it lacks support for modern features like TrustSec, Application Visibility and Control (AVC), or advanced SD-WAN constructs. It is a fossil from the CLI-centric era, which is precisely why it remains excellent for teaching fundamentals—BGP path selection, OSPF LSA types, and route redistribution—concepts that have not changed in two decades.
