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.
