Dynamips: Dynagen拓朴设计(.net)之以不变应万变 v4.0

Wandering 发表于 2008-05-05 12:12:30

.


v4.0 是在 v3.0 的基础上将设备型号从 3640 提升到 7206 (*注1)，目的是为了解决 3640 上存在的一些 BUG (*注2)，IOS 版本也随之发生变化。另外，对设备配置进行简化，所有的 ethernet 接口提升为 fastethernet。

升级后付出的代价是虚拟路由器耗用更多的系统资源，只是启动所有路由器＋不启动任何动态路由协议的简单的二三层连接的情况下，就会比 v3.0 高出 2－4 倍的 CPU 消耗。


*注1: 本来是提升到 3745，但 3745 在 linux 下有二次启动无法装载文本配置文件的 bug
*注2: 据说 3640 在虚拟机架的组播实现过程中会出现 ping 不通的问题

下面是启动 Dynamips 服务的批命令，上面的 .net 必须建立多个 dynamips 进程，而 dynagen 安装时自带的启动脚本只启动一个进程。把下面内容保存为名 start.cmd 的文件即可，注意 "start.cmd" 是文件名的全部，不要修改扩展名(当然 .bat 是可以使用的)。


@echo off
rem Launch a local copy of dynamips
start /belownormal /min "Dynamips" "c:\program files\dynamips\dynamips.exe" -H 7200
start /belownormal /min "Dynamips" "c:\program files\dynamips\dynamips.exe" -H 7201
start /belownormal /min "Dynamips" "c:\program files\dynamips\dynamips.exe" -H 7202
start /belownormal /min "Dynamips" "c:\program files\dynamips\dynamips.exe" -H 7203
