GNS3

GNS3 is a popular and capable network simulation application that network engineers and information technology professionals use to develop and test complex network topologies. GNS3 allows users to establish virtual networks, set up network devices, and test various network situations in a simulated environment. This tool allows users to drag and drop network devices and connect them to create complex network topologies. Moreover, It also supports a wide range of network devices, including Cisco routers and switches, making it a useful tool for network professionals who need to test and validate network settings. It may imitate network traffic and hence allow users to assess the performance and security of their network installations. 

If GNS3 is not working as usual at this time or maybe it’s down permanently then here are some of the best alternatives to GNS3 that you should consider utilizing.
