Cisco 7200 simulator scripts - user guide

Preface

This script is not a sophisticated scripts! Any comments and feedback please email to dc-at-dwichandra-dot-info

Quick Guide

If you need to use the scripts quickly, follow the steps below:

• extract the tar.gz file into any location (and remember this location, please)
• change the idle-pc value to the appropriate settings. The value provided works only in my environment, your environment could be different.
• obtain dynamips from ipflow here
• obtain Cisco IOS here (note: you must have appropriate access to obtain IOS. This script does not provide any)
• make a link of dynamips executable as 'dyna' in the main location that you extracted the tar.gz file
• unzip the IOS and name it as 'ios.bin'

That's it, you are now ready to run the lab sessions

To run several sessions at once, use the 'frunlabvolxlaby.sh' scripts as per appropriate router. x is the volume and y is the lab number.

The 'frunswvolilaby.sh' and 'frunbbvolxlaby.sh' are the scripts for running two switches and 3 BB routers

Note: the 'switches' is yet another 7200 simulator router that forced to be a multi-port bridge/switch based on configuration. I used this method to simulate a layer-3 capability of the switch.

DISCLAIMER

I am not liable for any damage after running this script in your box. Any settings have been set to meet the best awareness that I know in running it in a safe environment. However, unforeseen circumstances might happen differently in your environment.

My environment: Intel Xeon 3GHz (HT), 4GB ECC RAM, 3x120GB SATA (RAID5), 1xGbps NIC, Gentoo

During my lab session running using these scripts, the following things happen: processor and system fan running higher than normal, dissipated heat coming out at the back of the unit is hotter than normal (run it during winter, please) and the box never crashed (thanks to Gentoo with it's kernel fine tuning)

Anyway, I run the lab session from separate terminal using Multi-Gnome-Terminal

Have Fun!

Detailed Information

Technicals

What this script does is to create common topology based on Internetwork Expert workbook 3.0. Thus, the connection are through local UDP ports for each links for serial, ethernet and fast ethernet

Each router's console are reachable through telnet using the following port range: 19000 - 19012, details are as follow:

• 19000 is used for Frame Relay switch
• 19001 to 19006 are used for R1 to R6 (note the last digit number)
• 19007 to 19009 are used for BB1 to BB3
• 19011 and 19012 are used for SW1 and SW2 respectively
