I am not looking for technical config type solution as there are enough material use . I am looking at this technology for practical use and what is needed to have a DMVPN built in real world. Lets assume I have a datacenter room and I have a router and multiple branch locaions are connected to the internet DSL connections. In this scenario I am not using a single cloud but just different ISPs providing DSL connections.
In another scenario I want to understand how to create a DMVPN tunnel using a single ISP cloud.
I really need someone with practical experience on this as this is critical for me to understand. The books have too much non clear content as I have seen. If anyone can suggest a book with real world implementations will be great.
