The one thing in my control is preparation. Preparing for the CCDE was extremely hard for me. Oddly enough, the challenge wasn’t the complexity of the content, but the breadth. For example, stack the nineteen recommended reading books on your desk, and become an expert on them.

Look at the CCDE Practical Blueprint  -

The CCDE Practical Exam is designed to assess a candidate’s ability to perform the following
tasks:
Gather, clarify, and analyze existing and new network requirements
•   Identify requirements and determine how they shape the purpose and expectations of a
given network.
•   Demonstrate the ability to gather and validate information about an existing network.
Develop network designs to meet functional specifications
•   Choose the correct technology to resolve a specific network design problem.
•   Create a network design that minimizes or eliminates negative impact on the existing
network and services.
•   Create a network design that is scalable.
•   Create a network design that is elegant and supportable.
•   Create a network design that is resilient.
Develop a plan to implement network design changes
•   Evaluate the impact of implementation options.
•   Develop contingency plans for network restoration.
Convey design decisions and rationale
•   Justify network design choices based on functional specifications.
•   Justify technology choices based on technical requirements.

I used that outline, as well as the reading list to prepare. I think you will aggree with me that if you look soley at the blueprint, that you have to cast a pretty wide net to get all of it. I interpreted this as being so open, that it was like walking with a lantern. Light from the lantern shines equally on everything, so you pay attention to litterally everything. Now, after taking the exam, I gained a bit of perspective on what exactly the developers were looking for. In this case, it would be like exchanging your lantern for a flashlight. Now, while the beam is wide, it is a lot more focused then walking with the lantern.

This perspective on the exam, or more specifically the intent and target market of the exam is invaluable. Well, I guess it is valued at the seven hundred dollars it took to take the exam . Now that I understand what they are looking for, I think I am in a good position to have a decent chance in Febuary if I don’t walk away with a CCDE number in six weeks.

Pearson

Pearson’s professional testing centers were a new experience for me. The center was clean and professional, and the staff was very helpful (including getting a couple tankards of coffee after me explaining it was the lifeblood of us geeks). However the one thing, I didn’t get the same feeling that you get when walking into the CCIE lab. If you haven’t been to the CCIE lab yet, it is almost like walking onto the football field at Notre Dame. Where in the lab you walk past the wall of pain, at Pearson it feels just like sitting down and taking any other written exam.

I do have to warn anybody who is taking this exam in the future though. If you have big feet like mine, be VERY careful of the power plugs. I managed to kick the power plug from my computer just over an hour into the exam and lost all my work. Rest assured the proctors said that the test would keep state in the production exam.

Chicago

Prior to October, I had been to chicago four times. Sadly each of those times was limited to grabbing some spankitopita at the little Greek place at Miday and then flying on to some other part of the country. This was the first time that I had managed to escape the terminal and make it into the city itself.

The first thing that struck me was how Chicago went up and not out. Coming from the west coast where cities grow out and not up, it was very weird to look up and see 1500 foot tall buildings. This urban canyon was mixed in with buildings from the 1800′s. All in all I have to say that it was pretty cool.

All 1500 feet of the Sears Tower

The other thing about Chicago is that the food is AMAZING. In less then a week in the city I managed to put on two well earned pounds. We hit up Merlot on Maple the first night. It was a quaint little northern Italian resteraunt housed in a little brownstone on the southside of Chicago. The second day we hit up Dua, the second deep dish pizzaria in chicago for lunch. Then we went to Lockwood at the Palmer Hilton for dinner.  All these places were amazing, though I have to say that I prefered the down home delicious of Dua to the others.

Deep dish done right at Dua

The last night, it was time to blow of the stress from the CCDE Practical. The CCDE team was nice enough to host a cocktail party on the ninety fifth floor of the Hancock Building.  I managed to deliver a nice little diatribe on Trill, L3VPN’s and security networks a the user and app level vs. stopping at layer 4 while being about one beer past the point where technical items should be discussed. If I managed to get into any heated discussions aboutthe importance of business relevance versus technical optimization then you have my appologies.

Sadly that party ended at 10:00 pm. Luckily Chicago is Brian McGehan’s home town. He recommended Fado’ , a great little Irish pub in the russian hill section of town. Brian, Scott, Gene, Genes wife, Ryan and I headed down there and made a good time of it till 2:00 am in the morning.

Summing it up

Eighteen months of studying culminated in 8 hours of blurry eyes in front of a computer screen trying to figure out a proctor’s intent. Looking around at the people in the waiting room, I saw many people that just blow my brain away. So if they grade on a curve, I am pretty sure I’ll be back in Febuary. Even if it goes that way, it is a good thing, because it just pushes me to learn more and become a better engineer. At the end of the day, I’m all right with that.

From the network world editors -

Network World and the authors have decided to remove this blog post and the discussion that followed. While the original post was intended to highlight how the issue of braindumps is a pervasive one, we regret having singled out anyone in particular and apologize for any accusations of cheating.

I hope that Ethan is watching the outflow of support for him, and puts his site back up soon.Similar Posts:

Certguards inflamitory post about Ethan Banks removed from Network World Magazine

From Roberts article on networkworld

Ok, so Ethan doesn’t believe in violating the NDA that he had to sign umpteen times to get where he is now, but he’s promoting the use of Testking (a well known cheating tool) to “study” for his CCIE.

As a CCIE, I am obviously supportive of Cisco’s efforts to maintain the integrity of their (and my) certifications. And yes, Ethan was not exercising the best judgment by posting about Testking in a comment on his blog. Is that a reason to start a fire, and try to get his CCIE revoked? As a CCIE, my vote is a resounding no. While Ethan definately made a bonehead move, it does not change a couple things.

1. The CCIE written is just a gating exam, meant to limit the CCIE lab to individuals that have a chance (a notably slim chance) of passing the actual lab.
2. The CCIE exam, and its proctors are amazingly effective at weeding out cheaters. Yes, every once and a while a cheater manages to get through. But trust me, these guys get eaten alive when they look for employment.
3. Cisco has its own enforcement team and methods for finding cheaters, they have managed to keep Cisco certifications from devolving into the land of the MCSE. I think we should trust them to do their jobs, and more importantly trust their discretion.
4. Ethans site documented a very thorough preparation process as he walked the long road towards his CCIE. Sadly his site has been taken down, but in my opinion this shows that he put significant preparation in, and earned his number.

My take on things is that Ethan the target of a marketing scheme. From what I can see, Roberts efforts here are not focused on supporting Cisco’s certifications. It looks to me that he is trying to drum up traffic to his business. If you look at his products, there are $995 – $4,999 fee’s to become a “VIP site”. For your payment, you receive a seal of approval and a listing in the “VIP” area of his site.

Sadly, I have seen this scheme before in the photography world. Certain photographers have been known to set up review sites of other photographers. They build Google Page Rank (PR) on their site so they show up in searches relevant to their competition. Once they start showing up in those targeted searches they sell “VIP” listing or reviews. The photographers that pay up to become “VIP” members ensure that no bad reviews of their buisiness are put up on these sites.

Robert is running the same quasi extortion scheme, but for training vendors. I think this demonstrates a lack of integrity on Roberts part. There is no excuse for attempting to destroy Ethans name in order to make a few bucks. I refuse to condone his behavior and would hope that the editors at Network World feel the same and remove his blog from their site.

Ethan – If you read this, I hope you realize that me and others like me are on your side. You have obviously put stellar effort into both studying, and documenting your efforts. It is obvious to any reasonable person that you have earned the title of CCIE.Similar Posts:

1. Layer 2 Tunneling Protcol (V3) static and hairpin configuration example - my buddy Rick was nerding it out in the lab and sent a great configuration doc for L2TPv3 my way. L2TP(V3) is used to create a layer 2 psuedowire across layer 3 routed links. This is a great service provider tool that you can use in your own network, no MPLS needed .

2. SNIA Education – Fiber Channel Over Ethernet – There is a lot of buzz going around right now about Fiber Channel Over Ethernet (FCOE). There is also a lot of misunderstanding about the fundamentals of this architecture. This Storage Networking Industry Association (SNIA) does an outstanding job of covering FCOE at both at an architectural level, as well as going over low level messaging structures.

3. Trill (Rbridge) architecture – IETF internet draft – I think the last time I was this interested in an internet draft was when iSCSI was first being proposed in the IP Storage working group. Trill, in my opinion is basically a light weight version of MPLS / VPLS. It has as far as I can tell most of the advantages of this architecture, without some of the configuration and hardware requirement drawbacks. Fair warning, reading this document started a doc hunt that killed my Saturday.

4. Cisco’s Security Response to Sebastian Muniz’s IOS rootkit – Security is a very important aspect of network design. Sebastian’s IOS rootkit demonstration is going to force some customers who in the past have been “OK” with having older, possibly vulnerable IOS versions floating around to update their operational practices and start keeping their routers and switches operating systems as often as they do their servers. Thankfully, Cisco has been embracing technologies such as kernel virtual machines, in service software upgrades and more to lesson or remove the impacts of software upgrades.

5. Turning Wounded Warriors into Network Ninja’s – As a former Marine (well, always a Marine, formerly employed by the USMC) this program goes straight to the heart. Cisco is partnering with Naval Medical Center San Diego (NMCSD, or Balboa Naval Hospital for us locals) to provide technical training to Marines and Sailors who have recieved service ending wounds in Afghanastan and Iraq.Similar Posts:

Link Round Up – L2TPv3 FCOE Trill Wounded Warriors

Mike Writes -

“Hi Colin,
I’m an avid reader of your blog and had a question that I figured you could answer. I don’t have CCIE knowledge like I’m sure a lot of your readers do. I have worked for the same company for 6 years and during that time had been promoted into the Network Group where I was sent through class and earned my CCNA. The company I worked for decided to relocate across the country and so I have been looking for a new job. Finding a new job doesn’t seem to be that big of a deal but I noticed a lot of job descriptions are asking for BGP experience. We didn’t use BGP at my last job and I thought BGP is used primarily by ISPs for routing between Autonomous systems? If that is the case why do so many non-ISP companys list BGP experience in Networking job descriptions? What are they doing with it? Shouldn’t the ISP be doing the BGP routing for them?
Thanks!
-Mike”

Well Mike there are 3 primary reasons why a company would require (or want) BGP knowledge from its candidates.

Scenario 1. The company has an redundant Internet edge.

In this case lets call our company sample_company. Sample_company has its website hosted in a publicly facing DMZ and wants to make sure that its web servers are available in the case of an ISP failure. Normally in this case the company would request and Autonomous Systems Number (ASN) from ARIN and would get assigned a block of publicly routeable IP address’s (normally /24) that they can advertise. Sample_company would then peer with multiple ISP’s for example one connection to AT&T and the other to Sprint. Sample_company would advertise their ASN through both these ISP’s, and in the case of a failure of one of their ISP’s, the rest of the Internet would be able to calculate a path to sample_company’s web servers via the backup ISP.

Scenario 2. The company is utilizing MPLS for its WAN connectivity.

From a customer perspective MPLS is a private BGP based WAN where all edge devices connected to the MPLS provider utilize BGP to inject and learn routes. One note, some providers do support advertisement of routes via OSPF and even EIGRP now, but the most common scenario is to use BGP as your internal WAN protocol while running MPLS. One trend I am starting to notice, is that since companies are already using BGP on the MPLS WAN, they have started utilizing BGP as their primary routing protocol for their sites to avoid running multiple routing protocols and having to redistribute into BGP to cross the WAN.

Scenario 3. The company is using MPLS inside their data centers for segregation of business units.

In essence they are using the same tools and technologies that MPLS service providers are, however applying it inside of their data center and campus networks. In this case, BGP is the routing protocol necessary to carry the routes between the seperate MPLS VPN’s that are running inside the corporate data center. While this sounds pretty complicated, it actually simplifies many of the designs that you would normally implement to attain the same goals.

Learn more about BGP - Of course, there are many other reasons why you may see BGP on a job listing, but I think the previous covers the most common. If you are curious, and want to learn more about BGP I recommend buying Routing TCP/IP volume 2 by Jeff Doyle. This covers many great scenarios and configuration examples in EGP protocols. It is also written in plain English which can be a challenge with many technical books.

Learn more about MPLS in the enterprise - If you are feeling like learning about how you can implement MPLS inside of your own enterprise network then I would recommend buying Network Virtualization by Kumar Reddy and Victor Moreno. I was lucky enough to have Rick Davis translate the whole idea of utilizing MPLS in a campus environment into plain English for me a couple years back. From that point I was able to really expand my knowledge base and start asking the right questions from a firm foundational understanding of the technology. Kumar and Victors book took my understanding to the next level, showing how to incorporate many very cool features to make a MPLS network stand on its head if you want to. I can say (and actually have said to Kumar Reddy) that this book redefined my data center designs for large corporate and enterprise customers. I really recommend that you add this to your collection.Similar Posts:

Russ White – CCDE interview – Part 2

For the engineering perspective on this, the CCDE is equivalent  to the CCIE. However, the CCDE is focused on design and architecture rather then implementation. Where the CCIE (R&S, Voice, Security, Service Provider, Storage) is focused on implementation, the CCDE is focused more on the pre-sales design and architecture efforts. I am personally looking forward to the lab being released, as it provides a certification to validate the skill set needed to be an sales engineer on Enterprise accounts, or to be a network architect at an Enterprise corporation.

It is funny how small a world it is. Eplus (the company I work for) CEO – Phil Norton was quoted on Cisco’s press release -

“Certifications provide a stamp of approval that validates the quality of our organization’s employees,” said Phil Norton, chairman, CEO and president of ePlus. “The CCDE isn’t about operations; it’s about recognizing the value of network designers and honoring their core skills that provide a real value to our business and our customers.”

My gut feel when I first got invited to the CCDE beta program was that this will become a requirement for the Channel. I think Phil’s statement cements that gut feel into a reality. Obtaining a CCDE will become similar to the CCIE – a check box that you must attain to work with the top VAR’s out there. This makes me extremely grateful that I was lucky enough to be invited into the beta group to be allowed first crack at this gem of a certification.Similar Posts:
