Hi,
I found that the Aruba SD-Branch solution can support micro-branch or small-branch. Now I'd like to know how we can establish more than one wan links (or require additional devices) if using RAP or IAP. The main HQ would be Aruba controller 7000 series. If using 7005 at remote branch, there's no issue becasue it has many LAN interfaces. The solution concepts are like this picture.
