Gns3 installation and configuration guide for ccna network series experiments (1)

(I) install gns3
If the installation process prompts that winpacp has been installed, select "cancel"

(Ii) Configure basic gns3 Parameters

Select Step 1

General:
Configure two locations

① Path for storing the Topology
② Store temporary files

 

 

Dynamips:

① This is an important component for iOS simulation. It must be associated with the gns3 installation directory.

② Directory for storing temporary files

③ Then perform the test:

 

 

Capture:

Temporary directory for storing captured files

 

Qemu:

Store the PIX temporary file

Then test

 

 

Select Step 2

Here I use 3640 IOS

 

The idle PC value does not exist by default. It is available only after calculation.

Next, calculate the idle value.

 

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#

 

The idle can be directly used once after calculation.

 

 

(Iii) test:
