GNS3 is a graphical network simulator that allows simulation of complex
|
|
networks. To allow complete simulations, GNS3 is strongly linked with:
|
|
* Dynamips, the core program that allows Cisco IOS emulation.
|
|
* Dynagen, a text-based front-end for Dynamips.
|
|
* Pemu, a Cisco PIX firewall emulator based on Qemu.
|
|
|
|
GNS3 is an excellent complementary tool to real labs for Cisco network
|
|
engineers, administrators and people wanting to pass certifications such
|
|
as CCNA, CCNP, CCIP or CCIE. It can also be used to experiment features
|
|
of Cisco IOS or to check configurations that need to be deployed later on
|
|
real routers.
|
|
|
|
Features overview
|
|
* Design of high quality and complex network topologies.
|
|
* Emulation of many Cisco router platforms and PIX firewalls.
|
|
* Simulation of simple Ethernet, ATM and Frame Relay switches.
|
|
* Connection of the simulated network to the real world!
|
|
* Packet capture using Wireshark.
|
|
|
|
Important notice: users have to provide their own Cisco IOS to use with GNS3.
|
|
It is also recommended to read the documentation _before_ starting the program.
|
|
As of version 0.8.7 the package for dynamips has to be installed separately.
|
|
Port 127.0.0.1:7200 has to be open on your firewall.
