We are in process to implement DMVPN phase 3 and I have some questions:
1. Pro and Cons between single cloud and dual cloud
2. Can I achieve Stateful failover with DMVPN phase 3.
3. We would like to use OSPF any hints or document.
4. We would like also to use HSRP anu hint
5. How stable is DMVPN phase three compare to regular IPSEC and Get VPN
