My February 2017 CCDE class is now over. The duration of the course was for 11 days and as usual it started with lots of advanced technology lessons. All the critical CCDE exam topics (IGP, BGP , MPLS and the other technologies) were covered in detail from the design point of view.
A minimum of 4 hours was spent each day. We had 50+ hours training this time; which helped and engaged the participants during the training. For example, many existing CCDE network engineers shared the CCDE Practical scenarios, CCDE exam tips and tricks and their strategies with the students.
Since I adjust and expand my course outline continuously; each time, students learn more about network design. There were many CCDE Practical Scenarios at the February class and those scenarios definitely will help the attendees in the CCDE Practical exam.
By the way, the next CCDE Practical exam is on 22 February 2017, in 2 days’ time!
I wish all the attendees including my students ‘good luck’ in the upcoming CCDE practical exam. Looking forward to share their feedbacks and the success stories in the future posts.

As many of you know, I was born in Turkey. And unfortunately, the educational system of that country is very weak. And guess what: If you can’t afford to go to private school in Turkey, you may not be able to learn English in the government school. Read more
Do you need an LSP for MPLS ?
In this post, I will go through below topics. This is one of the points which network engineers struggle to understand as I have seen.
- What is an LSP (Label Switched Path) ?
- What was the purpose of having LSP in the first place?
- Do we need an LSP for MPLS and MPLS Applications such as 2547 VPNs ?
- MPLS over LSP vs. MPLS over IP Encapsulations
- MPLS VPN infrastructure in 2017
Should I use Cisco OTV for the Datacenter Interconnect? This question comes from not only from my students but also the companies which I provide consultancy.
I will not go through the OTV details, how it works, design recommendations etc. But let me remind you what is OTV and why OTV is used , Where it makes sense very briefly. Read more
Tier 1,Tier 2 and Tier 3 Service Providers
What is tier in the first place ? If you are dealing with Service Provider networks, you hear this term a lot. But how we define Tier 1,Tier 2 and Tier 3 Service Providers ?
What should be their infrastructure to be seen as Tier 1 for example ?
Which tier is bigger in scale ? Which one is better for the customers to purchase a service from ?
Why Service Providers claim that they are Tier 1 or Tier 2 ? Read more
Is fate sharing bad thing in network design? Someone asked this question recently on my youtube channel and I want to share a post for the website followers as well.
First of all, what is fate sharing ? Below is the Wikipedia definition of fate sharing.
” Fate-sharing is an engineering design philosophy where related parts of a system are yoked together, so that they either fail together or not at all ” Read more
One of the most important thing about CCDE exam is security. We all think that it is secure, it is not cheatable. There is no CCDE dump. We all believe that. CCDE exam has been around for more than 8 years and there are still only less than 400 people in the world. It seems what we think about exam security is correct.
But, keeping CCDE exam as secure is important and not hard. There are thousands of paper CCIEs around and we all know that. Nobody admit but people get CCIE number so easily. Of course there are many people also work hard, study hard and have it as well. Read more
Packet loss with Fast Reroute
Do we still lose packet with fast reroute? One of my students asked me this question. And I would like to share the answer with everyone.
Before we discuss whether or not we lose packet with fast reroute mechanisms, let’s remember what fast reroute is. Read more
Today, there are many networking technologies which haven’t been widely deployed. And among them are Internet Multicast and IPv6 although these two protocols have many benefits .
But probably people are asking the correct question. Do we really need new protocol ? Or can we solve our problem with the existing mechanisms deployed on our network ? Read more
Introduction to VPN (Virtual Private Network)
Let’s start with the definition. VPN is a logical network and created over shared physical infrastructure.
Shared infrastructure can be private such as MPLS VPN of a Service Provider or over the Public infrastructure such as Internet.
There are many concepts to understand VPN in detail but in this article I will cover the definition, common design considerations, and some not well known concepts about it.
We can group VPNs into two categories. WAN and the Datacenter VPN Technologies.
WAN VPN Technologies
