If you have Meraki MX security appliances chances are that you have seen the SD-WAN & traffic shaping option in the Meraki dashboard menu. Software-defined WAN (SD-WAN) can dynamically optimize your WAN without having to make manual adjustments when network conditions change. In a network with redundant uplinks if one uplink becomes degraded, SD-WAN allows the network to dynamically select the best path to the destination. This is especially important for latency sensitive services such voip and video. Meraki’s philosophy has always been about simplicity and their SD-WAN solution is no different.
One of hottest topics in networking is SD-WAN. Being the latest thing, organizations are not always clear on how, or why, to deploy a solution like SD-WAN.
Tomorrow is Valentine’s Day and while most of us are planning a special day with our special someone, here at LookingPoint we are thinking more about the technologies we are loving most this year! We want to share the love with our customers and blog subscribers, so we’re sharing the love with this list of the 5 enterprise technologies you are bound to fall in love with this year (if you haven’t already)!
This blog follows on from my last post and continues the discussion on how to integrate a single/pair of SD-WAN routers into our existing branch site topology. If you missed that last blog, then you can check it out here. Don’t worry I’ll be right here waiting for you.
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.
