Are you looking to build one, or do you have one and are experiencing issues?

Hello CCDECCDE9,
the solution reference network design for DMVPN is here:
http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/DMVPN_1.html
you can find design considerations and configuration examples.
Depending on the IGP of choice, for example 2) via hub is easily achieved with EIGRP and 1) with EIGRP requires tricks:
For 1) spoke to spoke
hub cannot summarize
hub requires split horizon disabled
hub has to keep the original EIGRP next-hop to give spoke1 the hint that some ip subnets are reachable via spoke2.
The basis for 1) is the capability to map also multicast packets with NHRP
Hope to help
