Redistribute NHRP and vice versa
Is it possible to redistribute NHRP learned routes (H) into another protocol and vice versa? If yes, what does the syntax look like?

Hi,
I'm not aware of this as being possible and I don't think it is because as NHRP routes appear in dmvpn phase 3, they are bassed on the underlying protocol that's being deployed between hub and spokes.
NHRP is not a routing protocol. It is used to resolve next hop addresses over a NBMA network. In some respects it's closer to ARP than a routing protocol. It is not possible to redistribute to/from NHRP.
Maybe you could explain what you are trying to achieve?
Can you not just redistribute the overlay protocol (ospf in your case) - the next hop on the DMVPN router will get sorted out on the fly with NHRP and a dynamic tunnel - and the route you send downstream/upstream will get the DMVPN router as the next hop, so there should not be a problem.
Hi,
As NHRP installs routes in the RIB, behind the scenes it is a routing protocol, but it is not configurable at this point (it's intrinsec behaviour is built-in the DMVPN code). With SDN it may become available for further development.

even though NHRP is not limited to DMVPN....it did exist before DMVPN from my understanding...
