Configuring VRF-Lite

ccie r/s ccnp r/s Jun 07, 2016

You’re probably familiar with the concept of virtualization, where you can run multiple virtual servers on a single physical server. However, did you know that you can run multiple virtual routers inside a single physical router?

 

That’s possible with a really cool Cisco IOS feature called VRF-Lite. This video shows you how to perform a basic configuration of this exciting virtualization technology.

WEBINAR REPLAY – Cisco Unified Communications Manager (CUCM): The Star of the Collaboration Show

ccna collaboration May 31, 2016

Earlier this month, I did a live webinar covering the theory and configuration of a CUCM server. If you missed it, you can check out a replay below.

Also, at the end of the webinar, I offered a big discount on a couple of my Collaboration products to those in attendance. Well, great news, I’ve reactivated the discount code. So, you can benefit from it too.

BREAKING NEWS – CCNA R/S Updated

Uncategorized May 17, 2016

It happens about every three years or so; Cisco updates its flagship certification, the CCNA in Routing and Switching. Today (May 17, 2016) is such a day, and current and future certification candidates are clamoring to learn, “What’s different?” That’s what we’ll uncover in this blog posting.

What Is The CCNA R/S?

First, let’s quickly review what the Cisco Certified Network Associate in Routing and Switching (CCNA R/S) is all about. Cisco tells us that if you have the CCNA R/S certification, you should be able to install, configure, operate, and troubleshoot a medium-size routed and switched network.

There are two paths that can get you to your CCNA R/S:

  1. One and Done”: You can earn your CCNA R/S certification by passing a single exam. I recommend this option for certification candidates with two or more years of real-world experience.
  2. The Two Step”: You can pass two exams (ICND1 and ICND2) to earn your CCNA...

5 Essential Books for Your Cisco Career

career success May 12, 2016

When I was around 20 years old, I used to go into bookstores and look for a book (something on a technical topic, a business biography, or on personal development) that I could afford. However, I recently went into a book store, and it occurred to me that I’m never going to be able to read all the books I’d like to read in my lifetime. So, now my book selection is less about getting a bargain and more about which books will have the biggest impact in my life.

In this blog post, I want to give you my recommendation for five books that have been significant to me and that I think will help you in your career as a Cisco networking professional. Interestingly, only one of the recommended books is a Cisco Press book. That’s because the specific Cisco Press books best suited to you greatly depend on your particular technology focus. So, the assumption is, you’ll have your own personalized collection of Cisco Press books in addition my five book recommendations....
