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>en
R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#int f0/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#end
R1#

 

                     

                      

                     

          IDLE只要计算一次，以后就可以直接用

 

 

         ㈢  测试：

R1>en
R1#conf t

R1(config)#int f0/0
R1(config-if)#ip add 192.168.1.110 255.255.255.0
R1(config-if)#no sh
R1(config-if)#end
