This cross-platform graphical simulation tool includes simulated catalyst switches. There are no 3G/4G support features simulated. It provides a simulated IOS with limited functionality based on incomplete characteristics. It uses the same Cisco IOS images as a real-time Cisco router and responds in the same way. Each router is expected to use about 512 MB of RAM. It does not use up any of the device’s RAM and is more lightweight. It allows users to access the operating system of routers, but not switches or other types of end user devices. It enables the use of CLI (command line interface) on switches, routers, and servers, as well as the addition of edge nodes such as voice phones, laptops, and PCs. Comparison Table Parameters of Comparison In GNS3, you may also use additional Virtual servers to connect with the routers, but in PT, the “hosts” only enable ping testing as well as DNS/DHCP configuration. GNS3 will typically be more feature-rich than PT’s (Packet Tracer) emulator because it boots genuine IOS images. Now I need to find some time for the Advanced Topology.The amount of resources (CPU / RAM) available on the PC for executing the lab’s simulated IOS images and virtual machines for clients & servers simulation is GNS3’s primary constraint.
