CCNA网络系列实验（1）之GNS3安装配置指南
㈠ 安装GNS3
如果安装过程有提示WINPACP已经安装过了，选择“取消”
㈡ 配置GNS3基本参数
选择 step1
一般：
配置两个地方
① 拓扑图存放路径
② 存放临时文件
Dynamips：
① 这个是IOS模拟的重要组件，必须关联上，在GNS3安装目录里有
② 临时文件的存放目录
③ 然后进行测试：
Capture：
存放抓包文件的临时目录
Qemu：
存放PIX临时文件
然后测试
选择 step2
这里我使用3640的IOS
IDLE PC的值默认是没有的，要计算后才有
接下来计算IDLE的值
R1>enR1#conf tEnter configuration commands, one per line. End with CNTL/Z.R1(config)#int f0/0R1(config-if)#ip add 12.12.12.1 255.255.255.0R1(config-if)#no shR1(config-if)#endR1#
IDLE只要计算一次，以后就可以直接用
㈢ 测试：
