CCIE - Internetwork Expert's Online Community

Hello,

I'm planning to buy the IE Dynamips workbook for CCIE R&S preparation. I recently loaded Dynamips to play around and feel comfortable with it before I purchase the workbook. I'm currently using c3640-jk9o3s-mz.124-12.bin. My PC specs are Intel(R) Core(TM) 2 CPU 6600@ 2.4 Ghz, 2 GB RAM. With the best idlepc value, my CPU and memory utilization are both around 65% when I start all my routers (R1 to R6, BB1 to BB3 and SW1 to SW4) with no configuration.

Just wanted to inquire about the following -

(1) Is a single PC with the specs that I have enough to run IE Vol 2 Wokbook for CCIE R&S preparation?
(2) With this CPU and memory utilization, will I hit CPU and memory overload issues as I start configuring these routers lab-by-lab?
(3) Is there a way to further improve the CPU and memory utilization in my setup. Find my .net file config below.

Appreciate all the help I can get. I have been stuck on this for quite a few days. Just want all these issues ironed out before I purchase the IE R&S Dynamips workbook.

Thanks for all your assistance!

Hello Brian,

Thanks for your reply. I want to try out the sample lab as you suggested. However, this lab if I understand correctly is based on the actual rack and not Dynamips. Is there a Dynamips sample that is available or is it just the same? Also the link you sent across only carries the questions. Is there a solution part as well that you can provide....just so that I can check quickly loading the config steps one after the other and test if my PC will stand up to the same.

Thanks for your time.

Regards,
Kartik

Hello Brian,

I managed to dig up the solutions guide on your site. Sorry for the trouble.

Kartik

Hello Brian,

I see that they Dynamips sample lab does not contain the entire lab but only initial portions of the same. Is there a complete sample lab and solution guide available for those who want to purchase your Dynamips workbook?

Also from your experience, will I be able to run the Dynamips lab on my Windows PC. I have set up the idlepc value and my CPU utilization after starting all devices with base configuration is around 10%. I'm running 12.4.12 Advanced Enterprise image and wanted to know if my PC CPU will be able to keep up with the subsequent tasks in the lab. I'm asking this since I believe there is no full Dynamips sample lab available for trial.

Appreciate your help!

Regards,
Kartik
