After getting familiar with the FA, when it’s set and when not, we’re ready to cook the recipe for chaos: NSSAs, Default Route injection and Forwarding Address.
Probably a good disclaimer for this article is – I agree, usually there are other, more simple and straightforward solutions to doing what I did, but in cases where you know 3 solutions to a problem, and none can be applied, it’s good to have the 4th one a click away.
Network Design
To begin with, the network design we’re going to be experimenting on today is not extremely common, but has a practical application though.
Configuration
I will start by not sharing the configuration files for this design, with a simple reason – Please lab it yourselves! You will have all sorts of things to gain from this, from typing rapidity, thinking the addressing scheme to troubleshooting your own mistakes. It’s not that big of a deal and it should not take you more than half an hour.
On a high level overview, everything you need to know is on the scheme. Nevertheless, here are the configuration principles:
Hey, it's HighScalability time:
I have traveled extensively over the final quarter of 2015, meeting with customers, prospects and partners. There is something about being on the road that gives clarity to business and as a result, it is clear in my mind that Information Technology is witnessing its greatest period of change. The Internet of Things, Cloud and Big Data are driving the massive growth of new applications and data. Rapid rates of application and data growth are forcing organizations to move away from legacy scale-up approaches to ones that provide seamless scale-out. Siloed and monolithic approaches to delivering storage, compute and network resources must be replaced by integrated and elastic infrastructure and services consumption models.
In support of these new consumption models, IT is being delivered as services delivered on-demand, leveraging cloud architectures. I am seeing the emergence of a new customer, whom I call the Cloud Builder or Cloud Architect. Due to the rapid growth and importance of this new role, I somewhat jokingly say, “the Cloud Builder has awoken.” This new role takes a different IT approach to meeting the needs of the business. The Cloud Builder looks at applications and data requirements from the perspective of business goals, Continue reading

As you know I always promise my loyal subscribers at least 6 new webinars per year. Well, 2015 was a bit more fruitful. Let’s start with the easy ones:
However, I spent most of my time developing the SDN and network automation curriculum:

In this first-ever episode of the Full Stack Journey podcast, I talk with Bart Smith (old GitHub account migrating to new GitHub account, YouTube channel). Bart shares some details about his journey from being a Microsoft-centric infrastructure engineer to what he calls a cloud-native full-stack engineer. Here are some notes from our conversation, along with some additional resources Bart wanted to share with readers/listeners. Enjoy!
