The solution is totally free, it doesn't require any additional license. It is also available on 6.0 and 6.2 but there are some differences in functionality and configuration steps. I will cover them in a separate post. Before we jump to the configuration steps I'd like to be sure you understand the concept of SD-WAN. The main goal is to have the ability to load-balance or just send specific type traffic using a specific path. It sounds similar to what you can achieve by using Equal Cost Multipath (ECMP) and policy-based routing (PBR). SD-WAN gives you something else - the ability to the perform load balancing by checking following three parameters: packet loss, jitter and delay. Let's' get started with version 5.6 and in this post I'll describe configuration steps for SD-WAN with two IPsec ...
