Graphical Network Simulator

GNS3 is a graphical network simulator that allows simulation of complex networks and to launch simulations on them. It is an excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications. It can also be used to experiment with features of Cisco IOS or to check configurations that need to be deployed later on real routers. You may configure devices ranging from Cisco routers, Cisco PIX firewalls, Cisco ASA Firewalls, Cisco IDS to JunOS routers using Qemu or Pemu. GNS3 uses dynamips as an emulation back end, an IOS emulator which allows users to run IOS binary images from Cisco Systems. Cisco IOS, PIX, ASA or JunOS software images are not included.
