We have a vibrant online community over at IEOC, and it’s only getting better as recently I’ve gotten commitments from a few CCIE Voice individuals who will be answering questions along with me, regularly there. So come one, come all, and post your questions relating to CCNA Voice, CCNP Voice and CCIE Voice.
Some of the more pertinent (Voice) forums are:
Also, if you are not aware, you are able to ‘subscribe’ at the bottom of each of these forums, and once you do you will receive emails for every new post (or digest if you so choose), making this a great combination mailing list and online forum, and you are free to use it either way you prefer, or even as both, as many do. You can also simply reply to any email, and it will automatically add your reply to the online forum thread, as well as alert all other members via email. You can even start new threads by simply emailing a new subject and body to the particular forum’s email address (once you get your first email from any given forum, you will know where to send new emails to start new threads).
We are highly committed to continuing to build IEOC into being the preeminent Voice online support community, just as it has been for CCIE Route/Switch for years now.
Finally, we have recently updated our Recommended CCIE Reading Book List. Head over there to check it out when you have a chance.
Transcripts, complete with click-to-jump links, are now active for the following All Access Pass* video playlists:
- CCNA Voice
- CCIE Routing/Switching Advanced Technologies Course
- CCIE Voice Advanced Technologies Course
- CCIE Security Advanced Technologies Course
The way the transcripts work is that there is a separate transcript for each video. So if you want the transcript for the 8th video in a given playlist, then you need to click on video 8, then click the tab for “Transcripts”. Then you can perform a CTRL+F and find whatever keyword you might be looking for, then once found, click on the link for that line and you will jump directly to that spot in the video. Soon we will be implementing a global search tool that will allow you to search through all transcripts in a given playlist.
I will keep this page up-to-date, and simply re-post the same blog article, each time a new playlist has a clickable transcript become active.
UPDATE: We Have a Winner!
Congratulations to Fredy and Antonis for both answering the question correctly.
Because we only had 2 answers to this contest (and it’s the second time we’ve run it), and they were both correct, as well as both having gone above and beyond the requirements to answer the basic question/problem, but adding additional correct and excellent configurations and annotations — we are awarding each of them the same prize!
At a most basic level, the problem with my configuration was that you cannot used an AS Numbered Instance of EIGRP at the top level to configure SAF (Service Advertisement Framework). Yes, EIGRP does have to have an AS#, but that must come within an EIGRP Virtual Instance Named (VIN)!
They both went above and beyond by pointing out many other great points that are well worth reading.
Congratulations to both of you, and look for my email in relation to your prizes!
By the way, since this is such a cool new technology that holds so much potential for real world production environments, I will do a follow-up blog post outlining the basics and some advanced topics surrounding CCD and SAF. Look for that here, soon.
Time for another INE CCNP Voice Trivia Contest. This week we will start early and give you until Monday 28 November to choose a winner, giving you a bit over four days to come up with the correct responses.
This is actually a re-post of an earlier contest –one containing knowledge that every CCNP Voice engineer must know to pass the CIPT2 (642-457) exam– that never met with a correct answer in the previous run. I have recorded around 4.5 hours of material on just this topic beginning here in this video, so take a look at these videos over the next few days, and see if you can sort out the answer.
INE is proud to announce the release of two brand new video products, the CCNA Routing & Switching Exam Course and the CCNA Routing & Switching Video Flashcards. Both of these products were written and delivered by Brian McGahan – three times CCIE #8593 in Routing & Switching, Security, and Service Provider – one of the most highly regarded and experienced CCIE instructors in the industry. Best of all, until Jan 1st 2012, streaming access is FREE to both the CCNA R&S Exam Course and CCNA R&S Video Flashcards, while download access to the CCNA R&S Exam Course is only $99! Additionally these classes support streaming to iPhone/iPad, Android, and Windows phone platforms, so you can take your training on the go.
To view these classes create a free account on the INE Members Site, then follow the links there once logged in.
Specifically the CCNA R&S Exam Course is a comprehensive look at the technologies covered in the Cisco Certified Network Associate (CCNA) Routing & Switching exams. With over 25 hours of instructor-led videos, this class contains both easy to understand and in-depth explanations, along with hands-on examples on the Cisco IOS Command Line Interface. The class will not only fully prepare you for the latest 640-822 ICND1 (CCENT), 640-816 ICND2, and 640-802 CCNA exams, but it will also expand your understanding of core technologies that are essential to know for beginning or advancing your career with today’s networks.
The CCNA R&S Video Flashcards are designed to help you test you knowledge before you sit for the actual ICND1, ICND2, or CCNA Composite exams. The thing that sets the Video Flashcards apart from other practice tests is that after every question, the instructor goes through a detailed explanation as to what the answer is, why it is the answer, and includes visual and hands on examples of the pertinent technology. We are considering adding Video Flashcard products for our other CCNA, CCNP, and CCIE tracks, so please post your comments below and give us some feedback about what you think of the Video Flashcard format!
Both of the above products are part of our larger All Access Pass video library. Available as a $159 per month or $1599 per year subscription, INE’s All Access Pass contains hundreds of hours of videos covering topics such as:
- CCNA Routing & Switching
- CCNA Voice
- CCNA Security
- CCNP Routing & Switching
- CCNP Voice
- CCNP Security
- CCIE Routing & Switching
- CCIE Voice
- CCIE Security
- CCIE Service Provider
- And more!
Feel free to post your feedback about the new CCNA videos here, or email Brian McGahan directly at email@example.com.
Each month we would like to say thank you to our top IEOC community members for answering questions, helping others and making it an all around great online Cisco certification support community. The awards for the top four most active October 2011 members go to:
- Alexander Halim
- Cristian Matei
We will be doing this every month, so keep posting answers to those questions, we appreciate it!
Also, since we know that our RS forums are much busier than our Voice boards are (simply out of more people studying for the RS exams across all levels), we’ve decided to also include another free iPad each month for the top Voice board poster. Note, this doesn’t include asking questions in the Voice forums, but rather helping out and answering questions for other posters. So Voice people – log on and help out! Also keep in mind that you don’t necessarily have to log on to the website to answer questions. You can subscribe to the various forums, receive posts via email, and simply reply to those emails, making it a dualistic forum/mailing list.
If you haven’t already noticed, we recently updated the layout and flow of our All Access Pass* video playlists. Of the more notable changes is the fact that as you resize your browser window, the video player auto-adjusts accordingly. We also now have the transcripts incorporated – along with their click-to-jump linking feature that will take you directly to the part of the video corresponding to the portion of the transcript you are reading. Currently, transcripts are available on the CCIE Voice Advanced Technologies Class, and by the end of this week/early next week we hope to have the CCIE Routing/Switching ATC and CCIE Security ATC transcripts live as well, with many more to shortly follow. Of course if you login to your AAP subscription, you also have access to the bookmarking and note-taking feature. One last note – to make transcripts work with click-to-jump on the iPad, first begin the video with the play button, then click the link next to the portion of the transcript you wish to jump to.
*All Access Pass (AAP) is INE’s subscription model, giving you access to every single video we have to offer in every discipline we cover. Currently with over 2,200 videos, and more being added each month, there is no more comprehensive Cisco-centric learning library available. AAP is available on a monthly or annual subscription basis. A 2-year subscription also comes complimentary with every purchase to our 10-Day CCIE Routing & Switching or 10-Day CCIE Voice Bootcamps.
I have quite a number of updates to announce for INE’s Voice program. First I will briefly outline them all, and then go into a bit more depth on each.

This blog post is the first in a series covering Performance Routing (PfR) formerly known as Optimized Edge Routing (OER) that I will be publishing over the coming weeks. I decided to cover PfR in a series of blog posts contrary to a single post as PfR is a very powerful and useful feature that leverages the power of Cisco’s IOS but at the same time PfR is potentially very complicated and often confusing feature to configure and troubleshoot. Trying to cover PfR in a single blog post would be the equivalent of trying to cover OSPF in a single blog post. In fact if you compare the IOS 12.4T OSPF Configuration Guide against the Optimized Edge Routing (OER) Configuration Guide you will notice that OER documentation is nearly 35% larger.
In this blog post the term PfR will be used in place of OER wherever possible as Cisco has started to depricate the OER terminology and commands as of IOS 15.0.
The primary focus of these blog posts will be how PfR relates to the Routing and Switching CCIE Lab Exam (PfR v2.2). The first couple posts will cover basic scenarios (static routing and BGP) with PfR, while introducing the reader to the PfR specific terminology and features as we use then and/or run across them. After we cover the basic scenarios I will get into more complicated scenarios using PfR to optimize routing based upon DSCP values, inbound routing optimization using BGP, routing based upon application response time and voice call quality. A final post will cover PfR in IOS 15.1 (PfR v3.0) and will focus on some of the newer PfR features. I will try to keep the details and complexities of PfR out of the first couple blog posts so that the reader can gain a solid grasp of PfR before moving forward. I spend roughly half a day in my new Routing and Switching CCIE 10 Day Bootcamp covering PfR as it’s important for the R&S CCIE candidate has a solid understanding before attempting the CCIE Lab exam. Additionally, I personally believe that in the future the concept of centralized route control and/or route manipulation as with PfR could become more common, similar to the concept of OpenFlow. With that being said lets get started.
Performance Routing (PfR), previously called Optimized Edge Routing (OER), introduces a new concept into IP routing. With traditional routing, path selection decisions do not consider a particular path’s traffic characteristics be it throughput, actual delay, packet loss, voice mean opinion score (MOS), monetary cost of a given path, or jitter. PfR enhances the classic destination-based routing concept centered on the shortest path (lowest-cost metric) by adding into the routing selection process, network performance and/or application performance aware intelligence. In the past when routing protocols were implemented in large-scale networks, routers did not have the resources to calculate the best path based upon anything other than a simple metric. Additionally, many of these networks would be considered simplistic in regard to the number of primary and redundant links compared to today’s networks. With the increase in CPU power and memory available in routers today, routing based solely upon a simple metric (hop count, cost, as-path length, etc.) is not the best use of these available resources. PfR will leverage these available resources to allow routing decisions based upon additional factors namely the networks performance and/or application performance across the network. Getting the most out of your network’s available bandwidth and/or the best possible performance for your applications across the network should be one of the primary goals of any network implementation. Let’s look at an example of how we can do this using PfR.
