Design overview
The basic building block of our SD-WAN solution is a Hub-and-Spoke topology, which we refer to as a region. The solution can include one or more regions, each of them typically served by one or two Hubs.
As mentioned in the Introduction, we are going to describe a generic deployment method suitable for SD-WAN solutions with an arbitrary number of regions, including a mixture of Single-Hub and Dual-Hub regions, sites of different sizes connected to different number of WAN transports, served by different Edge device models, and so on.
The following sections help describe the design of the managed Fortinet Secure SD-WAN solution:
