Cisco Meraki recently introduced the MG series Cellular Gateways to be a reliable solution as a backup internet uplink. In the event that the primary internet uplink goes down, the MG gateway will provide high availability for internet connectivity via wireless WAN connectivity using a cellular network. The MG Series also simplifies configuration and management using Meraki’s dashboard.

I am currently finishing a project where I am designing a custom Quality of Service policy for a customer's suite of business critical applications. The customer uses MPLS as their WAN and the bandwidth for the MPLS is different depending on the site; Datacenters have more bandwidth, branches have decent bandwidth, and small kiosks only have a few megabits of bandwidth. The customer noticed that...

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.

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...
