Having worked in Information Technology departments since the mid 90’s, I’ve seen a lot of change. As you might expect from technology, things move fast, as technology continues to improve at a rapid pace. But the biggest change I’ve seen is the feeling that most businesses have towards IT and IT spending. As a systems administrator in the 90’s I remember feeling as if companies never saw the true value of their IT departments, to the point where they were even described as ‘cost centers’. It felt like pulling teeth trying to secure a budget from the business for things that I felt were critical, such as proper backups with low recovery point objectives, and highly available networks that can withstand a failure without a big fire drill of scrambling engineers while hundreds of employees sit idly waiting for you to fix it.
In this edition of our SD-WAN series I’m going to take a step away from our lab environment and attempt to address a question I get a lot from our customers. “How do we integrate a SD-WAN router or pair of SD-WAN routers into our current environment?” Well the answer I’m afraid is the networking consultants classic line of “It depends”. And it really does, Cisco’s SD-WAN solution was created by engineers with a background in routing and this routing foundation really gives us a lot of flexibility when positioning our SD-WAN routers into our existing environment.
In my last post we looked at the steps that a vEdge goes through to bring up its control plane connections and authenticate itself onto the fabric. In this post we will follow on from where we left off and see how we use these control plane connections to exchange topology information, WAN policies and security keys via OMP.
Hello, my loyal blog post readers, in this my third installment of our SD-WAN series I am going to walk you through how our vEdge router locates, communicates and authenticates itself onto our SD-WAN fabric. Along the way we will take a look at a few packets captures and command line output to see what is going on under the hood.
In my last post in the series I introduced you to the four architectural components that control and enable our SD-WAN fabric. In that post I had promised that in our next installment we would take a closer look at our fabric bring up sequence, but if you will indulge me I would like to hold off on that topic for the next post. In its place I would like to use this post to introduce you to the lab environment that I have built for this series and take you through the process of deploying and registering a virtual vEdge router into our lab.
Over the past year I have been fortunate enough to work on several Cisco SD-WAN (formally Viptela) deployments. These projects have ranged from small three or four site implementations here in the bay area, right through to large scale international rollouts incorporating hundreds of sites spread-out across the globe with regional POPs providing branch services and backbone connectivity.
Day 2 of Cisco Live was filled with amazing new technology, new applications, new innovative services, and the power of Cisco’s partnerships. Cisco is continuing to build their intent-based networking with DNA, DNA Center now DNA Assurance. What really caught our attention today was the network and security innovations and integrations. Here are our top takeaways.
In January of this year LookingPoint Senior Solutions Architect, Chris Marshall, wrote a blog highlighting a technology we had just started hearing more about, SD-WAN. To recap, SD-WAN is an acronym for Software Defined Wide Area Network, and is a specific application of Software Defined Networking (SDN) that simplifies WAN management and connects enterprise networks. SD-WAN provides aggregation of WAN bandwidth, centralized control and policy enforcement, and visibility into network traffic.
Earlier this year Cisco released their new Digital Network Architecture (DNA), which they are calling “intent-based networking”. Cisco DNA is an open, programmable architecture that turns business intent into business results, and is the foundation for The Network. Intuitive. Cisco also released their Software-Defined Access (SD-Access) solution, which is the “industry’s first intent-based networking solution for the Enterprise built on the principles of Cisco’s DNA”. SD-Access provides
