Given that this is the Art of Network Engineering, I thought it appropriate to write about a book I recently finished, around creativity. Big Magic – Creative Living Beyond Fear by Elizabeth Gilbert sheds some light on what it is like to live a creative lifestyle. To me, after going through this book, a creativeContinue reading “Book Reaction – Big Magic”

Cooking up Coding Fun, from ‘Scratch’
Have you ever wondered of a fairly low effort, fun way to get your kids, friends, or family members into the basics of programming? Or maybe even yourself for that matter? On the surface, this can seem like a daunting task. I mean, when I think coding, I immediately default to command line and startContinue reading “Cooking up Coding Fun, from ‘Scratch’”
NFD30 – Gaining Intelligent Observability w/ Selector AI
Troubleshooting networks can be a very difficult, manual process. Businesses run disaggregated systems and operators often need to jump from one to another when trying to find and fix problems. A large amount of valuable time can be spent investigating different systems and infrastructure while trying to gather data, to then go through a manualContinue reading “NFD30 – Gaining Intelligent Observability w/ Selector AI”
NFD30 – Juniper Campus Fabric and Segmentation
Major goals for enterprise campus networks are flexibility, reliability, and security. With legacy networks, it sometimes seems to be difficult to get all three in one solution. For example, to build flexible networks, we would end up spanning VLANs across many switches and potentially compromising reliability. One solution to this is to adopt the underlay/overlayContinue reading “NFD30 – Juniper Campus Fabric and Segmentation”
Entry Level Cloud Certification
About mid-way through 2022 I was looking for the next step in my learning journey. Earlier in the year I had taken on an architecture role and saw it fit to start branching out from purely network infrastructure related concepts. It seemed like a good time to start gaining broader skillsets and knowledge. For me,Continue reading “Entry Level Cloud Certification”
You Are Good Enough
As I think it is natural for us to do near the end of a year, I have been doing some reflection. While ups and downs are often the norm, it seems to have been quite the year for many of us. All I have to do is check out the IAATJ Discord winning channelContinue reading “You Are Good Enough”
Smart Troubleshooting with PathSolutions
While troubleshooting issues is a fantastic skill to hone and practice, as network admins and engineers, it is not something we want to spend all of our time doing on a daily basis. Rather than constantly working through trouble tickets and “keeping the lights on”, we would like to use as much of our timeContinue reading “Smart Troubleshooting with PathSolutions”
Handling Toolbox Drama with NetAlly
As network/systems engineers and admins, the natural approach to something new is to start with training and understanding a new technology, job, project, or task. This is a valid approach, but many times is only half the battle. For practically any role, you not only need to understand the job and technology, but you alsoContinue reading “Handling Toolbox Drama with NetAlly”
Enterprise Network Automation with Itential
In this day and age, saying that enterprise networks are critical would be an understatement. Networks have essentially become a utility similar to electricity, gas, and water. When you turn that proverbial knob, those packets had better flow; and quickly! Except, the knob is stuck in the on position and never gets turned off. IfContinue reading “Enterprise Network Automation with Itential”
Be the Ally, Not the Ego
Competition is everywhere. Sometimes it is unavoidable. For instance, when you are looking for a job. You want to focus on you, skill up, and set yourself apart from the rest that are competing for that same job. It is definitely stressful, but can also be necessary when it comes to career advancement. Not always,Continue reading “Be the Ally, Not the Ego”
Planning and Maintaining Wireless Networks with NetAlly
For years now, the ability to be productive has been changing. In many cases, you do not need to be tethered to a desk working off of a computer that is wired into the network to get things done. We have evolved from that practice, to leveraging laptops, tablets, and even smaller mobile devices suchContinue reading “Planning and Maintaining Wireless Networks with NetAlly”
Climbing the ENCOR Mountain
This is not meant to be a “hooray for me” success story. The purpose of this post is to be a message of hope. I’m not someone who goes out and gets 10+ certifications a year. There is absolutely nothing wrong with that, I respect and admire the determination and focus of people that areContinue reading “Climbing the ENCOR Mountain”

OSPF Route Optimization – Route Summarization (Post 4)
You’ve made it to the 4th and final post in the OSPF Route Optimization series, I’m proud of you! I honestly wasn’t sure if I’d make it this far, myself. Anyway, in this post we will build upon the work we accomplished in post 3, in which we converted our flat, single area OSPF topologyContinue reading “OSPF Route Optimization – Route Summarization (Post 4)”
OSPF Route Optimization – Multi-Area OSPF (Post 3)
In this post of the OSPF Route Optimization series, we take a look at multi-area OSPF. As stated before, while single-area OSPF provides us with global IP reachability, it tends to not scale well from an efficiency standpoint as the network grows. In our sample topology, we will treat the “inside” zone of each siteContinue reading “OSPF Route Optimization – Multi-Area OSPF (Post 3)”
OSPF Route Optimization – Single Area OSPF (Post 2)
In this second post of the OSPF Route Optimization series, we take a look at our sample topology network configured with a single OSPF area. We will see that while we have global IP reachability throughout the network, the routing tables are not very efficient, and this design may not scale well. Here is anotherContinue reading “OSPF Route Optimization – Single Area OSPF (Post 2)”
OSPF Route Optimization – Background (Post 1)
When it comes to global reachability within an organization, dynamic routing is a beautiful thing. There are multiple internal gateway protocols (IGPs) out there, but in this series of posts, we are going to focus on OSPF. Taking this focus a step further, we will go through IP/subnet design and routing table optimization. As withContinue reading “OSPF Route Optimization – Background (Post 1)”
