It’s about that time of year again – with Cisco Live US 2014 just a few weeks away, INE has several new and exciting developments to talk about.

First, I’d like to invite all of you to join us at INE Rewired, our 2014 Customer Appreciation Party at Cisco Live. The party is on Tuesday, May 20th, 2014, at 6:00pm at the Mezzanine Nightclub San Francisco. We’ll be serving complimentary cocktails and appetizers, there will be over $25,000 in prizes and giveaways, and most importantly we’ll have a sneak peak at INE’s revolutionary new training platform, which will completely change the way you learn – but more on that coming soon. Second, we have two important announcements regarding new and updated products for CCIE R&Sv5.

On May 9th & 10th, 2014, I will be running an online CCIE RSv4 to RSv5 Transition Technologies Class. This online course is for candidates who have already invested a significant amount of time preparing for the CCIE Routing & Switching version 4 blueprint, but will be taking the lab exam in the new version 5 blueprint format that begins on June 3rd, 2014. This class focuses on technologies that have been newly introduced in the v5 blueprint, such as IPsec VPNs, DMVPN, GETVPN, and Embedded Packet Capture, as well as technology enhancements such as VTPv3, EIGRP Multi-AF Mode & Wide Metrics, EIGRP HMAC & OSPF SHA Authentication, Bidirectional Forwarding Detection (BFD), and OSPF Loop Free Alternative (LFA) just to name a few. All Access Pass members can attend the class for free, but customers who purchase the CCIE RSv4 to RSv5 Transition Technologies Class will have real-time access to ask me questions via chat and will also be granted early beta access to our new new training platform, which is scheduled for release shortly after Cisco Live.

Last but not least, this week we will begin releasing our updated CCIE Routing & Switching Version 5 Workbook. INE’s CCIE Routing & Switching v5 Workbook will collapse the previous four volume format used in our CCIE Routing & Switching v4 Workbooks into a single product. Customers who previously purchased either INE’s CCIE Routing & Switching Workbook Volume I or Volume II will have the new Version 5 Workbook automatically added to their INE Members account before the end of the week. Anyone who purchased just Volume III or Volume IV as standalone products can get in touch with sales@ine.com for special upgrade pricing to the new Version 5 workbook.

The new CCIE Routing & Switching Version 5 Workbook will be priced at $499, or $299 for AAP Members. However, if you purchase either the current Volume 1 or Volume 2 workbook before Thursday, you’ll still be eligible for the free upgrade to the Version 5 Workbook, and essentially save $300 on it.  Just don’t tell my sales team that I told you about this loophole ;)

Introduction

In a continuing effort to protect the integrity of the CCIE program, Cisco has announced a major change regarding the retake policy of the CCIE Written and Practical Lab exams. These changes take effect on August 1, 2014. Assuming a candidate happens not to pass on their first attempt at either a written or a practical “lab” exam within a given track, the frequency with which they will be allowed to retake the exam will change dramatically from past allowances, effectively not allowing the candidate virtually ‘unlimited’ retakes within a single calendar year (more specifically, within 12 calendar months from the date of the first attempt).

Changes to CCIE Practical Lab Exam

Perhaps the most interest for most people will be the frequency with which one will be allowed to re-sit for a CCIE Lab exam. Assuming a candidate does not pass on their first attempt at a given lab exam, they will still be allowed to attempt to retake the exam after 30 days has elapsed. The major change comes with the possibility that the candidate does not pass on their second attempt – after this attempt they must now wait for another 90 days to make their third attempt. Unlikely, but assuming a failure on attempt three, and a need to sit for attempt four, the candidate must wait another 90 days. Same goes for attempt four to attempt five. After a very, very bad year whereby a need to appear a sixth time becomes necessary, the wait period goes up to a full six months between attempts. The changes can be seen in a screenshot from a recent webinar below (after the jump).

Edit: The INE party will be at the Hard Rock *Hotel*, not the Hard Rock *Cafe*.

I would like to thank the over 600 people who RSVP’d for INE’s 2013 Party at the Hard Rock Hotel in Orlando during Cisco Live. Registration is closed as of today for our party but I wanted to be the first to let everyone know about the grand prize giveaway we are doing. On top of the standard giveaway prizes (iPads, MacBook Airs, AAP Memberships, Bootcamps, etc) we are giving away a Harley Davidson 2013 XL 1200X Forty-Eight to a lucky winner during our party.

Sportster Forty Eight

On top of the Harley Davidson 2013 XL 1200X Forty-Eight we’re having a second grand prize giveaway. Details on the second grand prize giveaway will be revealed after the drawing for the winner of the Harley Davidson at the party.

As a side note I don’t personally ride anymore but that bike really does look cool when it’s all blacked out.

As many of you already know I’ve been teaching our brand new Routing and Switching CCIE bootcamps for the past couple months. I’ve recently restructured the bootcamp in that mock labs are not done during the second week to allow for expanded coverage of the CCIE blueprint topics. The mock labs are now done after the bootcamp and I give every student 1500 tokens to schedule them. The new structure allows for roughly 100+ hours of hands-on demonstration using my own rack over the course of the two weeks. I start at 9am and go until roughly 8pm each night (Friday’s included). After 8pm the students usually go for dinner and start working on the labs and/or review for the next day. Every topic is covered hands-on by me during the two weeks. Students are given the R&S CCIE ATC Videos free of charge when scheduling the bootcamp because even with 100+ hours we do not have time to cover the basics.

As far as my teaching style goes Continue Reading

A new update to INE’s CCIE Routing & Switching Written Exam Bootcamp is now available in streaming format for All Access Pass subscribers, and available for purchase as a download.  This completely new video series, taught by me – Brian McGahan, 3 x CCIE #8593 (Routing & Switching, Security, Service Provider) – is specifically designed for students looking to focus on the topics and technologies covered in the CCIE Routing and Switching Written Exam version 4 blueprint.

As a precursor to our CCIE Routing & Switching Advanced Technologies Class and our CCIE Routing & Switching Lab Workbook Volume 1, the Written Exam Bootcamp helps to create a solid foundation of the concepts covered in the CCIE Routing & Switching version 4 Written Exam, as well to give students the knowledge they need to continue straight into their hands-on CCIE Lab Exam preparation. This bootcamp will also benefit current CCIEs who need to re-affirm their knowledge from a theoretical standpoint in order to recertify on the various technologies covered on the CCIE Routing & Switching Written Exam blueprint.

Samples of the class can be found here.

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.

NOTE
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.

I recently received an email from a student with a question about an example I did in our multicast bootcamp. After an hour into testing and drafting my email response, I realized this commonly misunderstood multicast design would make a great blog writeup! The original question is as follows:

Dear Brian

I am a customer of INE and bought the multicast bootcamp. Maybe I missed some important note, but I am confused related to the issue mentioned below. I am following the test bed you have shown in the presentation while describing the theory of sparse mode (Day 1 – Part 6) in which you have explained the RP Register, Join and SPT-Join.

Suppose the two trees are established, and traffic is flowing from the source to RP, and then RP to receiver. Also suppose that SPT-Join is disabled (e.g. threshold is infinity), and traffic always follows the shared trees.

Suppose that the multicast traffic flow is initiated from the source to the RP as follows:

R2 –> R4 –> R3 (RP)

Then traffic flows from the RP to receiver:

R3 –> R4 –>R5

When multicast traffic is coming from the RP on R4, will RPF check fail? I assume so, since multicast traffic is entering the interface in which RPF will be failed. Is there any other rule to follow if traffic is coming from RP?

Best Regards

Karim

Many times, students believe that they could use a bit of a boost when it comes to solving the very complex and difficult Practice Lab Exams featured in our famous Volume II workbook here at INE. To respond to this, Keith Barker and I came up with an idea for a new INE product unlike anything that had been created before.

We created a fully interactive video guide to lab exam strategy and actual solutions for the first five labs of the workbook. But we did not stop there. We also recorded bonus lessons on topic areas that students always seem to want extra guidance with. Such areas as:

  • Am I fast enough when it comes to making configurations?
  • What is the best way to master DOC-CD navigation?
  • What are appropriate strategies for Troubleshooting?
  • What should I do if I am struggling with Redistribution tasks?

Here are some sample lessons from the Interactive Video Companion for Volume II so you can see this remarkable product for yourself. I am also publishing the complete outline here so you can examine that as well.

Samples:

Lab 1 – Layer 2 Private VLANs

Version 4 Challenge – Speed Drill

Version 4 Challenge – MPLS L3 VPN Troubleshooting

The Course Outline:

Lab 1 – Dos and Donts – 20 minutes
Lab 1 – Lab Strategy – 30 minutes
Lab 1 – Backup Link – 20 minutes
Lab 1 – Spanning Tree Manipulation – 10 minutes
Lab 1 – Spanning Tree Security – 15 minutes
Lab 1 – Private VLANs – 30 minutes
Lab 1 – Layer 2 Traffic Engineering – 20 minutes
Lab 1 – OSPF Prefix Adv – 10 minutes

One of the most important technical protocols on the planet is Open Shortest Path First (OSPF). This highly tunable and very scalable Interior Gateway Protocol (IGP) was designed as the replacement technology for the very problematic Routing Information Protocol (RIP). As such, it has become the IGP chosen by many corporate enterprises.

OSPF’s design, operation, implementation and maintenance can be extremely complex. The 3-Day INE bootcamp dedicated to this protocol will be the most in-depth coverage in the history of INE videos.

This course will be developed by Brian McGahan, and Petr Lapukhov. It will be delivered online in a Self-Paced format. The course will be available for purchase soon for $295.

Here is a preliminary outline:

Day 1 OSPF Operations

●      Dijkstra Algorithm

●      Neighbors and Adjacencies

○   OSPF Packet Formats

○   OSPF Authentication

○   Link-State information Flooding
