简介:
What is GNS3 ?
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.
Qemu, a generic and open source machine emulator and virtualizer.
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.
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.
This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.
Features overview
Design of high quality and complex network topologies.
Emulation of many Cisco IOS router platforms, IPS, PIX and ASA firewalls, JunOS.
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 IOS/IPS/PIX/ASA/JunOS to use with GNS3.

1。安装完后运行“gns3.exe”，关闭”新工程“对话框后点edit--->preferences在跳出窗口点左边窗口的“General”然后在右边的"language"下拉菜单下选择“中文（cn）”，确认后，关闭“gns3”
2。重复上一步操作edit--->preferences在跳出窗口点左边窗口的“dynamips”，参数一般默认就可以了。然后点右边窗口最好后那个“测试（T）”按键，正常的话会在旁边显示 绿色 “Dynamips suceessfully started”，回车关闭当前窗口
3。选 择“编辑（E）”下的“IOS和Hypervisors”添加IOS文件发如图所示为添加思科7200系列路由器有关参数：
A。如果只拿7200做一般的路由实验的话128Mb就差不多了，要是安全相关实验最好给256Mb
B。至于“IDLE PC”是节省cpu开支的重要参数，该值为不是唯一的，最好是自己重新计算一下
