"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. "

Linux环境下测试过Debian(在VMware的虚拟PC中),可以跑起来.

下面都是Windows环境中(需要安装WinPcap)做的测试((版本0.2.3c,最新的是0.2.4命令好像有改变))

模拟三台设备互联
R1:
dynamips -p 0:C7200-IO-FE:udp:10001:127.0.0.1:10002 image.bin

R2:
dynamips -p 0:C7200-IO-FE:udp:10002:127.0.0.1:10001 -p 1:PA-FE-TX:udp:10003:127.0.0.1:10004 image.bin

R3:
dynamips -p 0:C7200-IO-FE:udp:10004:127.0.0.1:10003 image.bin


让emulato使用你的网卡
使用下面的命令后可以用Ethereal抓到emulator在你的网卡上释放的IP包!
dynamips -p 0:C7200-IO-FE:gen_eth:"\Device\NPF_{40371D28-B992-495E-AD5C-C3ED05DCB000}" image.bin
换句话,你可以结合Zebra或Quagga(和VMware的虚拟网络)甚至真实的网络设备测试了.

COLOR=red]"\Device\NPF_{40371D28-B992-495E-AD5C-C3ED05DCB000}" 在你的机器上这项可能不同,执行"dynamips.exe -e"确定.

相关问题

1.需要7200路由器的IOS镜像软件，可以去思科网站下载或用搜索引擎找.
eg:http://ftpsearch.rambler.ru/db/ftpsearch

2.根据不同的机器平台和系统选择不同的文件:

3.为了增快启动速度,可以预先对IOS镜像软件解压缩.Windowns中可以把后缀.bin改为ZIP后解压.

4.Windows中需要安装WinPcap,模拟器可以借用PC的网卡收发IP包.可以用Ethereal抓包分析.

5.最新版本是0.2.4与以前版本的命令有区别,具体参考
http://www.ipflow.utc.fr/dynamips/README-0.2.4.txt

6.UNIX/LINUX中需要libelf库,
Reahat参看(注意其讨论的版本):http://www.vmiao.com/article.asp?id=671

Debian(安装在VMware中)安装使用：
# wget http://www.ipflow.utc.fr/dynamips/d...s-0.2.4-x86.bin
# unzip -p c7200-js-mz.123-9.bin > image.bin
# apt-get install libelfg0
# ./dynamips-0.2.4-x86.bin -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10002 image.bin
# netstat -an

Proto Recv-Q Send-Q Local Address Foreign Address State
udp 0 0 127.0.0.1:10001 127.0.0.1:10002 ESTABLISHED

技巧交流
1.为了在UNIX/LINUX中安装和使用更方便可以使用SSH登陆后安装后使用.
2.Windosw环境下我是在几台PC上安装,先让让模拟器使用网卡启动,配制好IP.使用telnet登陆到路由器上.
3.可以结合Zebra,Qugga,Olive和真实网络设备测试路由协议的兼容性.




欢迎大家跟贴这个模拟器的使用案例.

请教，在Windows环境下，模拟多台路由器互联，用WinPcap还是VMware？

在Windows环境下需要用WinPcap,，只要多次运行各个命令(最好复制dynamips,Cywin1.dll,IOS在不同目录下运行)就能模拟多台路由器互联，
