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.

Just ahead of our brand new CCNA Voice live online bootcamp beginning this Monday, I thought it might be nice to provide an easy-to-follow graphic for those starting out in Voice (or on any other Cisco networking track). This graphic was from last year, but remains quite easy to follow for each and every Cisco track.

Be sure you have a high resolution set if you wish to see the entire thing, otherwise scrolling may be necessary.

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 bmcgahan@ine.com.

Today’s CCENT-level challenge involves the methods that are commonly used to describe and compare modern network infrastructures regarding such things as performance and structure.

ICND1-1: What common descriptive  characteristic for a modern network often encompasses a measure of the probability of a network failure called the Mean Time Between Failures or MTBF?

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

Catalyst switch port security is so often recommended. This is because of a couple of important points:

  • There are many attacks that are simple to carry out at Layer 2
  • There tends to be a gross lack of security at Layer 2
  • Port Security can guard against so many different types of attacks such as MAC flooding, MAC spoofing, and rouge DHCP and APs, just to name a few

I find when it comes to port security, however, many students cannot seem to remember two main points:

  1. What in the world is Sticky Learning and how does it work?
  2. What is the difference between the different violation modes and how can I remember them?

Sticky Learning

Sticky learning is a convenient way to set static MAC address mappings for MAC addresses that you allow on your network. What you do is confirm that the correct devices are connected. You then turn on sticky learning and the port security feature itself, for example:

switchport port-security maximum 2
switchport port-security mac-address sticky
switchport port-security

WARNING: You must master subnetting using our course or some other trusted materials before you start using these shortcut approaches. It is a common issue for Cisco candidates to move directly to subnetting shortcuts for the exams without fully understanding exactly how subnetting functions.

ICND1 (CCENT)

Question 3: Your co-worker has decided upon use of the 172.16.0.0 address space for a section of your network. This section requires 15 subnets. What subnet mask will you recommend?

Step 1: I reference the Powers of Two chart I created on my scratch paper when I encountered the first question. The forumla for the number of subnets you can create based on subnet bits is 2^s. From the chart I see if we “borrow” 4 bits we can create 16 subnets.

2^7=128  |  2^6=64  |  2^5=32  |  2^4=16  |  2^3=8  |  2^2-=4 | 2  ^1=2  |  2^0=1

Step 2: Borrowing 4 bits beyond the Class B boundary results in 255.255.128+64+32+16 = 240. Our mask is 255.255.240.0.

Question 2: You have run the ipconfig command and discovered your IP address and mask are 192.168.20.102 and 255.255.255.224. How many hosts are permitted on your subnet?

Step 1: I reference the Powers of Two chart I created on my scratch paper when I encountered the first question. Adding 128 + 64 + 32 = 224. There are 3 bits used for subnetting and that leaves 5 bits for hosts.

2^7=128  |  2^6=64  |  2^5=32  |  2^4=16  |  2^3=8  |  2^2-=4 | 2  ^1=2  |  2^0=1

Step 2: The equation for the number of hosts per subnet is 2^h – 2 where h is the number of host bits. From the chart I see that 2^5  = 32. 32-2 = 30 hosts per subnet! Too easy!

As always, let us know in the comments if you have a quicker approach.

Thanks to Randy of our CCNA program for this suggestion. Randy wanted some guidance on how to solve the subnetting questions in ICND1 and ICND2 very quickly. The ability to do this is often the difference between a passing score and a failed attempt.

WARNING: You must master subnetting using our course or some other trusted materials before you start using these shortcut approaches. It is a common issue for Cisco candidates to move directly to subnetting shortcuts for the exams without fully understanding exactly how subnetting functions.

For this series of posts, we will use simulated exam questions from ICND1 and ICND2. Well, with all that out of the way – let’s have some fun. You will find that once you “turn the corner” on subnetting, you will pray for many of these questions in the exam. It is an opportunity to solve questions quickly and be 100% convinced that your response is “spot on”.

ICND1 (CCENT)

Question 1: What is the last usable address in the subnet of a host with the address 192.168.1.134 and the subnet mask of 255.255.255.240?
