Dynamips - Route Simulator
For those who once attempted to obtain a license CISCO, they should have met such problem: they want to connect the device to do LAB, and the company network usually do not allowed. But to buy a device for the test is uneconomical, besides, those devices are always out of date, and some directives would be incompatible with the subject in the test.
For those who once attempted to obtain a license CISCO, they should have met such problem: they want to connect the device to do LAB, and the company network usually do not allowed. But to buy a device for the test is uneconomical, besides, those devices are always out of date, and some directives would be incompatible with the subject in the test. Although many manufacturers have developed a similar simulation program, but most of those programs are set so that they can respond to certain directives and create fake message, some use only FLAH to do simulation program, which has greatly restricted users.
Until recently, a foreign expert “Christophe Fillot” uses programming language Python wrote the simulation program Dynamips. What astonishing of the program is, it can read IOS image of CISCO and then issue instructions according to your IOS version. And you can run many virtual devices in one computer. Whatever agreements these devices should implement, the results will be truly reflected in Console.
The following is download site of the software:

The software program is open, note that the software will not provide
CISCO IOS image (Otherwise there will be a violation of intellectual property rights)Software creation and installment is not difficult. What you should pay attention is you must set a file, and this file will define the relationship of each device. For example, the interface of Router1 serial 1/0 is connected to that of Router2 Serial 2/1. This file is a text file, which can be directly edited. Following is an example for reference:
# Simple lab
[localhost] <— This means that all the devices are operated in the local machine, which also means that the virtual devices can operate in other machines.
[[7200]] <— This means that we will simulate the device Cisco 7200
image = Program FilesDynamipsimagesc7200-jk9o3s-mz.124-7a.image
<— this means the path you set your cisco IOS image
npe = npe-400
ram = 120
<— this mean the Memory you configured to virtual device.
[[router R1]] <— this mean you begin to define Router
s1/0 = R2 s1/0
<— this mean Router serial 1/0 should be connected to Router2 serial 1/0.
[[router R2]]
f0/0 = R3 f0/0
[[router R3]]
