Tomorrow, March 15th, we will air our March 2018 Networking Technologies Live Session with Keith Bogart. This course is designed for those with absolutely no knowledge of computer networks, but who would like to learn more and possibly head down a career path working on computer networks.


    March 16, 2018 10 am PST/ 1 pm EST

    Instructor Info:
    This Course is taught by Keith Bogart, CCIE #4923. Keith started his networking career as customer service representative at Cisco Systems in 1996. His desire to learn more soon led him to a position as a Cisco Technical Assistance Center (TAC) engineer on the “Dial-Access” team, and within six months he had obtained his Dial-ISP CCIE. He later became a network consulting engineer and obtained his CCNA certification while teaching the technologies to Cisco employees during his lunch breaks. Keith was the first instructor on Cisco’s TAC Training team, where he taught a wide range of internetworking topics and later developed and taught other courses such as routing protocols, LAN switching, MPLS, 802.1x, and CCNA. After almost 17 years with Cisco, Keith joined a small startup and focused on 802.11 Wi-Fi technologies, during which time he obtained his CWNA certification. He is now very happy to be working with INE as an instructor for Routing & Switching.

    Who Should Watch:
    Anyone with little to no knowledge about the IT and networking industry that would like to learn more.

    Why You Should Watch:
    This live session will allow you to find out more about what a computer network is, what types of things it can be used for, and what types of careers are available for those who want to design, install, monitor, and troubleshoot networks by asking questions, and discussing these topics with an industry expert.

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

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.


Question 3: Your co-worker has decided upon use of the 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
