Linux用dynamic模拟cisco路由器

    环境 : centos5.2

    软件: dynamic.cisco-ios

    1: 下载dynamic bin文件 .

    wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.6-RC4-x86.bin

    mv dynamips-0.2.6-RC4-x86.bin /usr/local/bin/dynamips

    2: 安装 需要用到的 libs.

    wget http://www.mr511.de/software/libelf-0.8.10.tar.gz

    编译安装：

    ./configure --enable-gnu-names

    make -j7 DEPSHALIBS="-lc"

    make install

    cp -r  /usr/local/lib/libelf.so.0 /usr/lib/

    cp  -r /usr/local/lib/libelf-0.8.10.so /usr/lib/

    3:下载 ios文件. 这里我以3640路由做例子: (其他ios 就自己去下了. 根据dynamics版本来看他所支持的ios)

    wget ftp://wolf:colorwolf5768@ftp.microwolf.net/nettools/ios/c3640-i-mz.122-13.T1.bin

    4:开始启动dynamips,并初始化路由:

    用法如下：

    dynamips -P <需要模拟的路由类型> -p 槽号:模块名 <对应路由的ISO文件名>

    路由的类型，目前可以是7200、3600、2691、3725或3745，缺省是7200。

    -p后面跟的是槽号:模块名，表示那个端口模块插在那个物理槽位（从0开始）中，具体的命令用法请查看官方文档。

    下面我们来模拟一台Cisco 3640，其中slot0接了一个快速以太网板，slot1接了一个4端口的E1。

    dynamips -P 3600 -p:NM-1FE-TX -p 1:NM-4T c3640-i-mz.122-13.T1.bin
