We may have some site-to-site vpn solution available
I want to use DMVPN and chose OSPF as IGP.
Is there anyone who can help me by giving suggestion for the Optimal and scalable solution for my network by considering the WAN resources?
Thanks

If you're going to use DMVPN, you may want to take a look at this document:

Which goes over the different DMVPN redundancy options.
