Labs 1 and 10 of the new CCIE Routing & Switching Lab Workbook Volume 2 Version 5 (IEWB-RS) are now available on the members site. INE’s CCIE Routing & Switching v5 Workbook will collapse the previous four INE’s CCIE Routing & Switching Workbook Volume I or Volume II will have the new Twenty full Dynamips practice labs are now posted as part of our best- selling. The R&S CCIE Volume 2 workbook has been ported to our new web format (see below). Currently the IP Routing section has been ported. Notice that the Dynamips edition of VOL2 workbook could be purchased Frame-Relay Switching.

I had experimented with Dynamips in the past and found it very useful. So what is Dynamips? Christophe Fillot is the author and maintains a technical blog here. Since the software emulates the hardware you can run IOS on it and basically have a virtual router.
Better yet you can connect you can run multiple instances these virtual routers and connect them together to create virtual topologies. So Cisco is completely cool with this? In order to run a virtual router instance you need to have a copy IOS software to run on it. While Dynamips is an amazing program, it does require a lot of resources in order to run multiple instances of virtual routers.
The IE labs use 6 routers, 4 switches, a Frame Relay switch, 3 backbone routers, and a terminal server. You can run smaller topologies on boxes with less horsepower.
I am running it on Ubuntu 8. Most users do not work directly in Dynamips but rather interact with that program via a front-end program.
Two of the more popular front-ends for Dynamips are:. Dynagen — a very popular text-based Dynamips front-end. Many with step-by-step videos. This is your best resouce for finding out Dyanmips information and dynami;s your Dynamips questions answered.
Our stock is in the crapper and the US is in a recession since December of last year it seems. Needless to say, work has not been fun. Winter is now here and that means a bunch of home projects.
School is in full effect, so I have to make sure my son spends more time studying than watching Cartoon Network and playing Lego Star Wars not an easy task. Did I mention that winter is here? I fucking hate winter. I love Minnesota, but only for 9 months a year. I have done two complete labs since my failed lab attempt. I have been working on technology-based labs, but my CLI sessions have been few and far between. Which, to him, means that we need to learn voice technologies.
Not how to troubleshoot existing voice implementations in our network, but rather learning generalized, low-level voice technologies. The good news is that the worst is over. The freeze change starts next Monday so work will quiet down. I should have time available once again to jump into my studies. I have to sit down and create a study plan and stick to it. I was able to get the full IE topology running. I now have the Dynamips Workbooks from IE as well. Everything was rocking until I got to the BGP section of the lab.
I was disappointed because I really want to use Dynamips so that I have a virtual rack available at any time. So I bought myself a Christmas gift:. Of course right after I ordered this I found a tutorial on how to run Dynamips across multiple boxes. This will give me a box to run a full IE Dynamips topology on so that I can lab during any free time I get at home.
It also has a picture of one of the Brians McGahan — at Networkers? The bit that caught my interest was this post concerning the official Cisco non response concerning Dynamips.
For Cisco, Dynamips is a boon. It is allowing more certification candidates to get hands-on emulated experience with their products.
Most of that market was being served by eBay and used equipment vendors anyway. GNS3 looks like a very nice tool for designing networks with Dynamips. I find it very easy just to swifching the. I may give it a test run just to see if I can export the graphical representations beats making them in Visio.
Both parts of this workbook are available exclusively in electronic format. I finally dropped a gig stick of RAM in my laptop it was at megs and fired up Dynamips.
This class is scheduled to be available some time during the week of 17 — 21 September.

Swtching original dates have since come and gone, but today I see that they have a page up dedicated to using Dynamips on a Mini Mac. No COD at this point, but lots of good information.
It was bound to happen. Today I started doing some BGP labs that required 5 routers. Dynamips kept dumping its core ewww! I finally realized that as soon as the IOS loaded on the 6th device 7th if you count the Frame Relay switch Dynamips would crash. This is probably due to my laptop.
I only have Meg of RAM. I dropped the RAM on the Dynamips router instances from to I was able to get all 6 devices up and working. Memory allocation of bytes failed from 0xB8D6C, alignment 0 Pool: Not enough free memory Alternate Pool: I finally stripped the switch out of the rojting I just directly connected the couple of routers on Ethernet segments and bumped the RAM back to Internetwork Expert just sent out their September newsletter.
If you are a customer of Internetwork Expert and you pass your lab, you can send them your name, CCIE number, and mailing address and they will send you a free polo shirt with your name and CCIE dynammips on it.
I thought that I would share some of my experience with Dyanamips.
