USING 802.1q, QnQ AND A BREAKOUT SWITCH

A brief overview

GNS3 is an excellent platform for simulating a good sized router environment for testing and more importantly for preparing for your CCIE lab. There are, however, some known limitations. The Dynamips software does not currently support more up to date switches like the 3560s used in version 4 of the CCIE Routing and Switching lab. In GNS3 on Ubuntu, you were provided with guidance on setting up GNS3 on Ubuntu GNU/Linux. You were shown how to run it as root and also introduced to the .net file that ultimately drives your lab topology. Dynamips and GNS3 (for the purpose of this article we will refer to it simply as GNS3) both support extending your virtual topology to your physical Ubuntu host. This gives us some very creative options for merging our virtual topology with physical hardware. We will use this article to demonstrate one of two different ways to extend your virtual topology to your physical hardware via some simple .net file adjustments and network configurations. You should already have a reasonable understanding of the fundamentals of Dynamips, GNS3, and the .net files before going too deep into this. You also are expected to have a reasonable knowledge of GNU/Linux and of course Cisco switching. Remember. Google is your friend.

Here is what a few CCIEs who attended an IPexpert CCIE Bootcamp had to say about it;

“This is exactly what a 90%-ready-CCIE-wannabe needs: this last touch of expert’s input in order to clarify all the potential doubts and make the candidate 100% certain in his knowledge”. -CCIE# 27555 (Voice)

“The 5 day CCIE Boot Camp was very helpful, it helped me to clarify a lot of misconceptions.”-CCIE# 27855 (R&S)

“This class really helped me in building my confidence to try an attempt on a Lab”.-CCIE# 27751 (R&S)

“This is really a fine-tuning exercise, the days are long and you can fix any weak points and dedicate time to tasks with a world-class CCIE instructor on hand to produce live demos and answer questions. You have a dedicated CCIE rack to use and again increase speed.”-CCIE# 20078 (R&S, Sec)

“The course provided me the information necessary to give me the final push in my CCIE studies.”-CCIE # 27568 (Voice)

“They really want to form you into a true CCIE, not just someone who can pass the test. I am greatly indebted to the amount of work they put into the materials that they offer.”-CCIE# 26625 (R&S)

This was brought up by two students in the security online study list but I thought it was worth mention.

You can add regular expressions to NBAR class-maps for HTTP URL matching protocol maps.

Note: This article is not directly related to the CCIE exam as EEM TCL Scripting is not on the blueprint.

With the continuing growth of the IT industry it seems that often the push is to do more with less. As a Network Administrator there are common tasks that many do day to day that really are a waste of time. In my opinion anything you can automate will help in removing mundane tasks you do from day to day and decrease your workload. So learning automated tools that can decrease your workload is one of the best steps you can take for yourself.

In this tutorial I will show an example script and walk through the script to hopefully enable you to better understand EEM TCL Scripting.

Join us in congratulating the following CCIE on his great achievement;

• Bojan Zivancevic CCIE# 28189 (R&S)

Bojan Zivancevic CCIE# 28189

“I am pleased to announce that I passed CCIE Routing and Switching exam on the first attempt. I used IPexpert CCIE R&S  workbooks extensively and I can only recommend these materials wholeheartedly. The greatest value I had from them is learning how to think non-linear and tackle the labs from all sides. The labs make you think non-linear and are a great help in forming the mindset for the actual exam. Also, the troubleshooting sections were challenging and I enjoyed working on them in preparation for the actual TS section on the exam.

OnlineStudyList is a great resource tool. I am very thankful to Tyson Scott and Marko Milivojevic, IPexpert instructors, because their response times were always incredibly small. You will also find many other CCIEs there, as well as CCIE candidates, all willing to help and participate in the discussions. Last but not least, I am very satisfied with the help and support from the IPexpert sales department. It is not common to find such devotion to a client’s satisfaction in the industry.”
