hello Jorge, could you tell me pelase why we cannot use VPN spilit horizont or just routing to separete that traffic between WAN and Internet. Let's say the Main Office uses 10/8 network. Why we cannot create 2 rules:


10/8 ---> WAN
0.0.0.0/0 ---> ISP.

Why would I need whole SD-WAN solution for a task that can be done on ANY router?

every single video i have seen reagarding mpls and sd wan, i am just not able to understand how it works. this is so frustrating and depressing

[SovetUnion]

It is funny, let's assume that cost of the network is $0, I mean ANY network. You start with the argument that MPLS is costly. Let assume we achieve via super duper SD_WAN $0 . What does it mean? IT meas hundred thousand unemployed IT specialists. All this "designed" SD-WAN, or Cisco ACI have one simple goal, make it cheaper for consumers. I asked on one ACI training session Cisco rep. How much workforce reduction ACI will cause? How many IT guys will go home unemployed? They have no clue. Soon will be one massive HYPER-VISOR and no one around, well... until it fails, but all IT tech will die from starvation. Remember movie Idiocracy? Year 5001, all is automated, but no one can troubleshoot anything.
