Simulate a cisco router with dynamic in Linux

Article Title: simulate a cisco router using dynamic in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Environment: centos5.2

Software: dynamic. cisco-ios

1: Download the dynamic binfile.

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

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

2: install the required libs.

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

Compile and install:

./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: Download the ios file. Here I will use the 3640 route as an example: (other ios will download it by myself. According to the dynamics version, we can see the supported ios)

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

4: Start dynamips and initialize the route:

The usage is as follows:

Dynamips-P <需要模拟的路由类型> -P Slot Number: Module name <对应路由的iso文件名>

The type of the route. Currently, it can be 7200, 3600, 2691, 3725, or 3745. The default value is 7200.

-P is followed by the slot number: Module name, indicating that the port module is inserted in the physical slot (starting from 0). For specific command usage, see the official documentation.

Next we will simulate a Cisco 3640 instance. slot0 is connected to a fast Ethernet board, and slot1 is connected to a 4-port E1.
