CentOS6 install Cisco simulator Dynamips

The Cisco simulator runs in a Windows environment and consumes resources. Therefore, Dynamips is installed on the CentOS6 Linux operating system to simulate Cisco routing and switching.
1. Download:
Download several required packages
[Root @ cisco test] # wget http://www.ipflow.utc.fr/dynamips/dynamips-0.2.8-RC2-x86.bin
[Root @ cisco test] # wget ftp://ftp.pbone.net/mirror/dag.wieers.com/redhat/el6/en/i386/dag/RPMS/dynagen-0.10.1-1.el6.rf.noarch.rpm

Description: dynamips package. You can download the RPM package or binfile.
Ii. Installation
1. You can directly install the libpcap package, a DVD or an ISO file.
[Root @ cisco test] # rpm-ivh/media/CentOS_6.0_Final/Packages/libpcap-1.0.0-6.20091201git117cb5.el6.i686.rpm

2. Install dynamips
[Root @ cisco testing] # cp dynamips-0.2.8-RC2-x86.bin/usr/bin/dynamips
[Root @ cisco test] # chmod + x/usr/bin/dynamips
Note: The binary file is downloaded and the executable file is renamed to the corresponding location. If it is an RPM file, install it directly.
3. Install dynagen
[Root @ cisco test] # rpm-ivh dynagen-0.10.1-1.el6.rf.noarch.rpm

4. Download the Cisco ISO file
5. Write a topology script
Iii. Run and use
1. Run the Dynamips daemon (it can be written as a script)
The script is as follows:
 
[Root @ cisco test] # start-dynamips.sh vi
#! /Bin/bash
Echo "* ============================================ ============= *"
Echo "**"
Echo "*..*"
Echo "* I *"
Echo "* III *"
Echo "*. II... II .*"
Echo "*.: iii I iii:...: iii I III :.*"
Echo "* C I s c o S y s t e m s *"
Echo "* BY: ganxing *"
Echo "* ============================================ ============= *"
Echo "* Console for 3640 Router *"
Echo "* ============================================ ============= *"
/Usr/bin/dynamips-H 7200 &

 
2. Write a topology file (simulating a one-way switchover)
[Root @ cisco test] # vi test.net
 
Autostart = False
[Localhost]
Workingdir =/tmp
Prot = 7200
Udp = 10000
[[3640]
Image =/root/c3640-jk9o3s-mz.123-10.bin
Ram = 128
Idlepc = 0x6045bcec
[[ROUTER R0]
Model = 3640
Console = 2000
Slot0 = NM-4E
E0/0 = SW f0/0
 
[[Router sw]
Model = 3640
Console = 2001
Slot0 = NM-16ESW

 
3. Compile the startup simulator script
[Root @ cisco test] # vi start. sh
 
#! /Bin/bash
Echo "* ============================================ ============= *"
Echo "**"
Echo "*..*"
Echo "* I *"
Echo "* III *"
Echo "*. II... II .*"
Echo "*.: iii I iii:...: iii I III :.*"
Echo "* C I s c o S y s t e m s *"
Echo "* BY: ganxing *"
Echo "* ============================================ ============= *"
Echo "* Console for 3640 Router *"
Echo "* ============================================ ============= *"
/Usr/bin/dynagen test.net
