I have attached a document in this. Please have a look.
I have used three different ISP intranet link. I want to connect the Head office LAN from remote office LAN, which is shown in the green line. What will be the proper design for the DMVPN ? I have drawn a red line of my design, is this the good design or not. If I go according to my plan I don't have to create different VPN's for each ISP.
Or, Do I have to create the VPN between point to point link of each ISP, please guide ?
