Dynamips: Open-Source Cisco Router Emulator
Create virtual Cisco routers on your computer with Dynamips, an open-source router emulator supporting various Cisco IOS images and features like virtual interfaces, routing protocols, access-lists.
What is Dynamips?
Dynamips is an open-source software that emulates Cisco routers. It allows you to create one or more virtual Cisco routers on a regular PC and connect them together or to virtual or physical devices.
Some key features of Dynamips:
- Supports a wide range of Cisco IOS images from older routers to newer models like 7200, 3600, 2600, 1700, etc.
- Virtual routers behave close to real hardware with features like console access, interfaces, routing protocols, ACLs, switching, etc.
- Allows you to lab complex network topologies with routers, switches and PCs on your laptop without expensive hardware
- Integrates with GUI front-ends like GNS3 for easier configuration
- Lightweight and efficient thanks to Dynamips's dynagen technology
- Open source software with an active developer and user community
If you're preparing for Cisco certifications or want to test networking scenarios, Dynamips is a great alternative to real Cisco gear for home labs allowing faster experiments.
