Top 4 Download periodically updates software information of GNS3 for Mac 2.2.6 full version from the publisher,īut some information may be slightly out-of-date. * Connection of the simulated network to the real world!
* Simulation of simple Ethernet, ATM and Frame Relay switches. * Emulation of many Cisco IOS router platforms, IPS, PIX and ASA firewalls, JunOS. * Design of high quality and complex network topologies. This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.
It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers. GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE. * Qemu, a generic and open source machine emulator and virtualizer. * Dynagen, a text-based front-end for Dynamips. * Dynamips, the core program that allows Cisco IOS emulation. To allow complete simulations, GNS3 is strongly linked with : GNS3 is a graphical network simulator that allows simulation of complex networks.
