So many students that pass on a first, or subsequent, attempt of the lab exam emerge to profess the importance of a complete “mastery” of the documentation that is available during the lab exam.

I wanted to bring together in one place here on the blog, three blog links that are designed to assist you in this regard. Enjoy these free training resources!

First, watch this hour-long, complimentary session from the Open Lecture Series on Mastering the DOC-CD:

Click here to watch the video.

Second, it is time to practice what you learned in this interactive DOC-CD exercise:

Click here for the DOC-CD Interactive Video.

Finally, this blog post points out some very useful DOC-CD locations that students have really enjoyed:

One of the fun things for me about helping with the new CCDP Bootcamp is learning about technologies you do not get exposure to in the “traditional” Routing and Switching curriculum that are based on mid-level and low-level Cisco hardware. One of those technologies that our new course will cover is Bidirectional Forwarding Detection (BFD). This technology is found on Cisco 6500/7600 series routers, as well as 12000 series and Carrier Routing System (CRS-1 Routers).

Like many of the features covered in the Routing Protocol Design section of the course, Bidirectional Forwarding Detection seeks to speed up routing protocol convergence. The key factor in this goal addressed by BFD is the fast detection of node or link failure in the routing design.

Many approaches to the fast detection of the failure of a link or neighbor deal with some type of accelerated hello packet (fast hellos at Layer 3). BFD operates along a similar line,except the fast link hellos are accomplished at Layer 2. The CPU impact of the BFD process ends up being much less compared to other fast hello approaches. Cisco has tested systems running 100 concurrent BFD sessions between routers and noticed an increase in CPU utilization of a mere 2%. And remember, that was with 100 concurrent sessions running.

In order to take advantage of Cisco’s BFD, we not only require the correct software and hardware version, but we need the cooperation of the routing protocol. Fortunately, BFD functionality has been engineered into OSPF, EIGRP, IS-IS, and BGP, as well as such important “support” protocols like HSRP.

If you would like to learn more about BFD right now, visit the Cisco DOC-CD.

I would like to let you know that I passed my CCIE R&S 4.0 lab exam after applied for the re-read of my exam; I want to share my painful but lucky story:

I attempted my CCIE lab on 03-Oct-2010 in Dubai, but I failed in troubleshooting. My mind didnt accept this result because i was quite sure that i did well in troubleshooting section, so I immediately applied for re-read. At last after three painful weeks, I got an email from Cisco that your result has been changed from fail to pass. I am feeling very lucky because it happens very rarely that re-read change the result and make it ultimate for you.

I would like to give special thanks for the wonderful QoS boot camp which helped me a lot to understand the most boring topic “QoS”. I would also like to thank the entire INE team for providing me such a great R&S 4.0 training..:)

Muhammad Tahir Munir, CCIE #27270

Congratulations Muhammad, CCIE #27270!!

Share in Muhammad’s Success! Save $300 on the QoS Bootcamp when you use discount code 27270!

Note: the 642-642 QoS Bootcamp Class on Demand comes with an audio version, interactive version and recorded bootcamp version.

Introducing the changes

As you have probably heard already, Cisco announced changes to the CCIE SP blueprint, that go effective as of April 17th 2011. There is some good news and some bad news. On positive side, the new blueprint looks really good technology-wise – just look at the detailed checklist here: https://learningnetwork.cisco.com/docs/DOC-10145 and see the mentioning of VPLS, Carrier Ethernet, FRR and other features. On the opposite side, the equipment requirements for the new blueprint put extensive toll on an average CCIE candidate’s budget (unless you work for a big Cisco partner and can “borrow” equipment for your lab). The new test will build upon XR12000, 7600, 7200 routers and ME3400 switches – for more information look here: https://learningnetwork.cisco.com/docs/DOC-10121. One problem is that Cisco did not yet specify the detailed hardware requirements, e.g. linecards for the routers. The other problem is that “simulator” mentioned in the hardware specification. There is no doubt that Cisco has software emulators for IOS XR routers and 7600 devices, but it is not clear whether those will be available to general public.

Based on the above observations, we are still considering the impact of changes on INE product offering. While our product line will definitely stay there, we will not officially announce any changes to our hardware specification while we wait for more information from Cisco regarding the hardware and availability of simulator software. It is our priority to keep the CCIE training affordable to the students, and thus minimizing the rack hardware cost is very important.

Join me tomorrow, October 22nd at 12:00 PM PST / 3:00 PM EST, for the free vSeminar: Unified Mobility Interactions with Local Route Group and Globalization.

To attend this free vSeminar, use the following URL tomorrow at 12:00 PM PST / 3:00 PM EST: Unified Mobility Interactions with Local Route Group and Globalization

In case you missed any previous vSeminars, be sure to check out the recent updates here.

If you are interested in learning more about technologies covered by the CCIE Voice Lab Exam, check out INE’s Voice Deep Dive. The CCIE Voice Deep Dive is the ideal way to gain in-depth knowledge about specific topics and technologies. We’ve now just completed 17 modules, and unlike other Class on Demand’s that only go to 20 or possibly 25 hours, ours now span over 95 hours of training, and we still have more to go. It truly doesn’t get any “deeper” than this. We will post an update with the complete new table of contents to these 3 newly released Deep Dive modules on CUCME, next week.

Hope to see you tomorrow!

CCIE instructors see the question time and time again – are we penalized for “over-configuration” in the CCIE lab exam? The answer – “not typically”. Let us walk through some examples to see exactly what we are talking about here.

First of all, I encourage students to ask two questions when they are about to “over-configure” something. Question 1 – can this additional configuration I am about to make actually gain me points (might Cisco be grading for it)? Question 2 – can this additional configuration I am about to make actually hurt me (cause point loss)? If the answers are a resounding YES and NO, then it is definitely a configuration you should consider making.

In the first part of this series, we examined WEP as presented in our CCNA Wireless Course. To read that first part, click here.

The WiFi Alliance introduced Wi-Fi Protected Access (WPA) in 2003 as a replacement technology for WEP. WPA is based on the 802.11i draft version 3. This improved technology relies upon Temporal Key Integrity Protocol (TKIP) to automate the changing of keys. Remember that a huge issue for WEP was the single, static key in use. Interestingly, WPA uses the RC4 encryption algorithm like WEP; although Advanced Encryption Standard (AES) can also be used if desired.

Well I finally did it!  After a year and half of studying practically every day I am happy to say I am CCIE #27143!  I am proud to say I failed the exam 4 times, I wear each one like a badge of honor.  And for $1,400 each, those badges are made of a rare gold/titanium/diamond composite material, they are beautiful.  My road to becoming a CCIE had many unexpected twists and turns.  I got my CCNA back in 2002.  I studied for 2 months and passed it on my 1st try, so I must be pretty darn good right?  Well in 2005 I decided to try for my CCNP.  I soon discovered I had let my CCNA expire, so I had to retake that first.  Within 6 months I passed the CCNA and all 4 CCNP tests, so I must be the man right?  Then I got my first real networking job and soon discovered that I was truly just a paper champion and had no clue how to design or configure anything.  I learned on the job and quickly got up to speed.
