[edit]Introduction
I started recently (August 2005) a project to emulate a Cisco 7200 on a traditionnal PC. This kind of emulator would be useful to:

Be used as a training platform, with software used in real world. It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies ;
Test and experiment features of Cisco IOS ;
Check quickly configurations to be deployed later on real routers.

Of course, this emulator cannot replace a real router, it is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP/CCIE exams.




[edit]Current status
At this time, the emulator I have programmed is able to boot a large number of Cisco IOS releases available for the 7200 platform, including the latest 12.2S and 12.4.

The following devices are emulated in the current release (0.2.4):

MIPS64 CPU processor. The instruction set is not completely emulated now (FPU support is lacking, TLB support is not finished and other minor things), but it is sufficient for IOS ;
DRAM and Packet SRAM memory ;
Non-Volatile Memory (NVRAM) ;
Signetics SCN 2681 DUART (Console and AUX ports);
Dallas DS1620 Temperature Sensors and Voltage Sensors, allowing the Environmental Monitor to work properly ;
NMC93C46 Serial EEPROM ;
Bootflash of 8 Mb (Intel 28F016SA) ;
I/O and Midplane FPGA specific to the C7200 platform ;
Basic Galileo GT64010/GT64120 PCI controller, DEC 21x50 PCI bridges and so.
Ethernet cards "C7200-IO-FE" and "A-FE-TX" based on DEC21140 chip ;
ATM card "A-A1" based on Texas Instruments Tneta1570 chip ;
Serial cards "A-4T+" and "PA-8T"

New features in 0.2.4:

Serial interface support to allow use of PPP/HDLC/Frame-Relay encapsulations
Virtual Frame-Relay switch with basic LMI support (ANSI Annex D)

You can also get some tips/development info... on my technical blog (http://www.ipflow.utc.fr/blog).

To run at a decent speed, the emulator uses a JIT (Just In Time) compiler, which is working on x86 CPU (like Pentium) and x86_64 CPU (AMD64/Intel EM64T). It is also possible to run the emulator without the JIT support on non-x86 machines, but it is slower.

You can find some information about the C7200 hardware on the Cisco Web site (http://www.cisco.com/en/US/produ ... 6a00800942e0.shtml)

[edit]Download
The current release is 0.2.4, published Feb 14, 2006 (you can consult the README file (http://www.ipflow.utc.fr/dynamips/README-0.2.4.txt)).

You have to download only one binary file corresponding to your architecture:

Executable for Linux/x86 (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.4-x86.bin)
Executable for Linux/x86_64 (AMD64 and EM64T) (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.4-amd64.bin)
Executable for Windows (with Cygwin DLL) (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.4-cygwin.zip)

If you are using the Windows version, you have to download and install the WinPcap library (http://www.winpcap.org/). It is now possible to access the Ethernet card of host machine to send/receive packets on the LAN.


You can also download the source code, published under the GNU General Public Licence (GPL):

The source code of release v0.2.4 (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.4.tar.gz)

Remark: the sources include 3 files which are not written by me: pcireg.h from NetBSD (http://www.netbsd.org) (under BSD licence), amd64-codegen.h and x86-codegen.h from the Mono project (http://www.mono-project.com), under GPL licence. Of course these files keep their licences and their copyrights.




[edit]How to use it ?
To boot quickly, the preferred method is to decompress the IOS image with the "unzip" utility. It avoids to run the self-decompressing process in the emulator.

chris@portchris2:~/mipsemu$ unzip -p c7200-g6ik8s-mz.124-2.T1.bin > image.bin
warning [c7200-g6ik8s-mz.124-2.T1.bin]:  27872 extra bytes at beginning or within zipfile
  (attempting to process anyway)
chris@portchris2:~/mipsemu$ file image.bin
image.bin: ELF 32-bit MSB executable, cisco 7200, version 1 (SYSV), statically linked, stripped
You can ignore the warning, unzip has just skipped the self-decompressing code at the beginning of the image.

Now, you can boot the image:

chris@portchris2:~/dynamips-0.2.4$ ./dynamips image.bin -t npe-400 -p 0:C7200-IO-FE -s 0:0:udp:10000:127.0.0.1:10001 -p 1A-A1 -s 1:0:udp:10002:127.0.0.1:10003 -p 2A-8T -s 2:1:udp:10004:127.0.0.1:10005

看不太懂

dragonfly

有时间试试

dccall

7200 IOS IMAGE 在哪里下载？

dragonfly

cisco网站

liufirst

这个好，我得试试。这两天翻译一下传上来。好玩呀。

牛肉小丸子

试过了，什么命令都可以模拟，可惜有点耗资源，同一台机器模拟多个7200，机器会吃不消

dccall

谁能将IOS Image放出来，谢谢。

lovellh

有没有实际应用，，

hlf

Win系统下如何做，具体步骤那位能给说一下？
多谢

hlf

同台计算机模拟的多台7200之间是否可以互联或者有什么方法可以连接外部设备？

那位兄弟知道？否则只是一台的话就没什么意义了。

牛肉小丸子

当然可以互联了，但是我还不知道怎么模拟WINDOWS客户端与路由器

hlf

在winXP,和win2000下试了，非常占用资源。

我看介绍有的说可以互联，有的说不行。设了IP但ping不通外部实际设备。我在启动命令中只加载了三个模块和引擎，是否还要加载其它选项才能互通？

dragonfly

还是能ping通外部设备的．启动时加上如下参数：
-p 0:C7200-IO-FE -s 0:0:gen_eth:"\Device\NPF_{D7CBC7BB-8CB9-473D-9516-FB9DCFA28805}"
其中双引号内的内容可以用：
dynamips -e
得到，每个网卡是不同的

dragonfly

在FreeBSD下运行也很占资源．
