In the first ever post of the AONE CCNA Series, we are going to start from the top. If you are following along on the CCNA exam topics, we will be covering Network Fundamentals > Explain the role and function of network components > Routers. Routers represent a critical component of network infrastructure in thatContinue reading “CCNA Series – Routers”
Here at AONE, we believe in continuous learning and development. We also want to do what we can help those trying to break into the network engineering field. While by no means the only factor, certifications can help you gain applicable knowledge for a specific career path. They can also be used to prove toContinue reading “CCNA Series – Overview”
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)”
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)”
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)”
This article first appeared on Andrew’s blog – andrewroderos.com As many network professionals know, Type 0 (cleartext) passwords are a big no-no. With that said, Cisco introduced Type 7 and 5 passwords in the early 90s to protect stored passwords. However, after more than 25 years, the Type 7 password type no longer serves its originalContinue reading “Protecting stored Cisco IOS passwords”
This article is written by Ben Story and originally appeared on his blog packitforwarding.com Recently I opened a TAC case through my Cisco Partner. In the initial automated response from Cisco TAC, I noticed something new. There was a link (https://tacconnect.cisco.com) that I had not seen before. Since it mentioned a bot, I figured whyContinue reading “TAC Connect Bot – Devvie Has a Sibling!”

So, you’re either thinking about or being “encouraged” to get certified in one of the many exciting and new Cisco certification offerings?
Either way, that’s fantastic news!
Ok, first things first; Cisco, (like many other certification granting entities), have long since developed proven formats for designing certification exams as well as the supporting documentation that accompany them to aid candidates in their quest in getting certified. For every certification exam, there is a certification “blueprint”, a syllabus of sorts.
AONE co-host, A.J., recently completed all the requirements for his CCNP Enterprise – read all about his journey to the CCNP here!
Enter the world of Automation and Programmability, with AONE Blog contributing author Esteban, as network engineers it’s often scary to learn that things are changing at a fast pace if you don’t know where to start Cisco new certification DevNet Associate is the right fit for this purpose, this is a short but powerful read on what to expect, how to prepare and what resources do you need to be successful.
