To make it easy for you to do experiment I list the corresponding module information that every device can support. (bat file)

(for those beginners in dynamips)
Attention: Make sure your IOS version is 12.2s above. To guarantee the success of the experiment, the IOS version should be 12.3 above.
Begin with C7200
Slot 0:

C7200-IO-FE <——> support one Fastethernet interface
C7200-IO-2FE <——> support two Fastethernet interfaces (there is no such option in DynamipsGUI 2.3 you should add it by yourself)
C7200-IO-GE-E <——> two ports would appear at the same time when you insert this card:Ethernet0/0 and GigabitEthernet0/0 (I never use such card)

attention: these three cards can only be inserted in Slot0. It would be useless to insert it in other slot.
Slot 1-5:

Hi all,
here are some idle pc value that I have tested,but some of them not work.
If anyone have another good idle pc value, please report to me and I wil collect all together. I think it may help some new comer that do set up the network quickly.

In continue to people comments and notes on the subject I would like to write a small doc here on how to Work with Dynampis on linux

First you can download Dynamips from here and I recommend to use 0.2.6-RC5 (both for linux and windows)

extract all to /home/dynagen
mkdir /home/dynagen/images // for the IOS Image
mkdir /home/dynagen/working // for Dynamips server outputs and memory emulation
and extract your IOS image to it

After you extract the binary (unless you know what you are doing I recommend to to waist your time with the Source). you need to create a shell file that will open localhost ports of Dynamips on your PC and this you can see in my artical

Then all you need to do is to start the lab that you want from the labs I have given by
do not forget to change the IOS image name to fit what you are using and to check your idle-pc as it is important if you want to work with more then one router. you can find more info on idle-pc here

./dynagen

Network successfully started

You are probably wondering what I’ve been up to lately. I’ve actually been quite busy with decorating my new house, planning for my wedding, and studying for my R&S lab. I’ve given up chasing the Security lab for a while until after my wedding. Having just moved into my new house a few months ago, it took a while before I could set aside a storage area to house all my equipment. Believe it or not, I just started to tear down my R&S and Security racks which were housed at my parents place not to long ago.
I haven’t decided whether or not I’m going to rebuild these racks at my new place just yet. While I have more than enough room in the garage, I’m not quite sure owning your own hardware these days is the way to go. If you haven’t read my blurb on the dynamips emulator, I’d glance at it to get an idea on what I’m talking about. Dynamips & dynagen have opened up a whole new way of running virtualized routers for me on my desktop. I already have it fine tuned to the point where I’m running it on all my home machines and work machines.
Just about a month ago, my harddrive at work died. Luckily enough the workstation was still under warranty and HP sent out a new drive. While I was waiting for this new drive to arrive, I booted up my machine with an Ubuntu Live CD. As soon as I was up and running again, I downloaded a copy of dynamips and dynagen and loaded up 11 routers. I pushed for running a 12th router, but apparently the Ubuntu Live CD didn’t allocate enough memory. Just running the 11 routers allowed me to get in about 4-5 hours of studying that day.

Summary
The principle of dynamips is to simulate hardware platform of CISCO Router, run CISCO software directly, and to achieve almost complete simulation of CISCO routers and switches effect while dynagen is to make it more convenient for you to use and the configuration more humane on the basis of dynamips. This paper is an instruction for dynagen to use dynagen in windows xp. In addition, its use and configuration in Linux and other platforms is basically the same. You can use this software on the basis of this paper to achieve simulation running of numbers of routers on single or more PCs and to realize their interconnection. This is helpful for you to study CISCO router figuration on network. This is the supplementary information about running numbers of routers on one or more PC (windows) and realizing their interconnection. The latest version can support switch module, but temporarily I don’t know how to use switch on it. Would someone please tell me if you can?

Hardware and software requirements

1. Operating system I use is windows xp sp2, and my computer is Lenovo Yang Tian Series, with 1G EMS memory.

2. You can download dynamips, dynagen and WinPcap in the enclosure.
3. As chris has said, CISCO BIN file cannot be offered, but if you have bought CISCO product, these are no problem.

After the following configuration, the fa0/0 of R1 、 R2 、 R3 are then in a conflict domain, like joining to a switch. When the address of the three interfaces on the same segment, they can ping with each other.

Emulatedhardware

By default, aNPE-200 is emulated. You can choose the NPE type with the”-t” option.It is
possible to select “npe-100″, “npe-150″, “npe-175″,”npe-200″, “npe-225″, “npe-300″ and”npe-400″. The “npe-g1″ is not working.
Please note that you must use the C7200-IO-FE PA driver as IO card if you want aFastEthernet interface in slot 0.
For other slots, you must use the PA-FE-TXdriver.

DynamipsPosted by r0ckwell on August 10th, 2006
A few weeks ago before my 1st Security Lab attempt, I stumbled upon a Cisco 7200 simulator called Dynamips. I basically perused the website to see what it was all about. I didn’t seriously start looking into the emulator until after my failed attempt. The reason being is because I didn’t want to lose focus on my security studies. Now that my failed attempt is behind me, I reinvested some time in using the emulator. Believe me when I say this, you will never have to purchase any routers again using this emulator. It pretty much does everything you want. Once I got the basics down in using Dynamips, I was able to redefine my IPExpert R&S labs, InternetworkExpert R&S Core labs, and my Trinet Security labs using this emulator. While you have to run the frame-relay emulator within Dynamips, all your frame-relay mappings work with ANSI configured as default.
At work, I have an HP xw4300 Workstation with a Pentium 4 CPU of 3.00Ghz and 1GB of RAM running Windows XP. I have read several posts that people were running more than 8 routers within their emulator, but not quite sharing how they acheived this. I had to do a little digging around, but found that they were using Dynagen, a front-end application written specifically for the Dynamips emulator. After tweaking the template files that come with Dynagen, I managed to figure a way to run 11 routers, 2 switches, and 1 frame-relay switch. Just to give you an idea of what I’m talking about, here’s my Dynagen config:

There are many courses of using GHOSTIOS characteristics in NET files, but you can rarely find any in BAT files. Based on the CMD help in DYNAMIPS, finally I find some ways of using GHOST in the BAT files after a long day’s studying.
The computer configuration I’m now using is AMD Athlon 64 X2 Dual Core Processor 3600+ 1.9G, with an EMS memory of 448. When GHOST characteristics are not used in BAT files, I start a 3620 dynamips instance and a 3640 one with a switching module, my memory usage is as following:

The following is methods of using GHOST characteristics
