GNS3 VS Mininet

If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: 6 months ago

GNS3 is the software your looking for it can be found here https://gns3.com let me know if you could use some resources on it. Source: 10 months ago

GNS3 is a network device emulator, and more than a few devices requires lots of CPU and RAM resources. You need to pay for a licence for each device you want to emulate. Source: about 1 year ago

You might want to look into GNS3. It's a network emulator that supports Cisco ISO devices. It's been a while since I last used it, but at the time I found it to be indispensable as a learning tool. Source: over 1 year ago

You can learn routing even on a host in Linux with iptables as well as Linux network namespaces via mini net http://mininet.org/ etc. once you’re comfortable there you can start looking at docker networking and also frr as well as gns3 or eve-ng running virtualized routers.

Or instead of using Docker, you can also get a Mininet VM, (optionally) install a desktop environment on it and create any manner of network configurations to tinker with, and use Wireshark to analyse traffic. Source: about 1 year ago

You can learn BGP with mininet: https://mininet.org/ You can simulate arbitrarily large networks and internetworks with this, provided you have the hardware to run a large enough number of virtual appliances, but they are pretty lightweight. - Source: Hacker News / almost 2 years ago
