I've been looking for a way to create a point-to-multipoint Tunnels between Hub and Spoke routers until I found assistance here (Configuring Point-to-Multipoint IPSec Tunnels).
After some testing, I realized that the DMVPN won't be sufficient since I will require a backup Hub router. So after searching, I found that this can be done using DUAL DMVPN, but unfortunately, I couldn't find any config guide for that.
I would appreciate someone to provide me with a guide for the DUAL DMVPN.
