I found a how-to from Petr describing how the DMVPNs are working and I was wondering if there is such topic in the lab because I didn't notice it in the blueprint.

It's mainly for the security lab because it's typically an IPsec feature. It's essentially an automatic full mesh of lan to lan IPsec VPNs.
Thanks Brian. I got a strange task from a friend who had 4 routers in the broadcast domain and he had to configure OSPF between two of them without using the secondary address. I solve the case with GRE tunnel in between but according his SG this case should be solved with multipoint GRE + NHRP (dmvpn) ; I do know what NHRP does,however, if you you have just two routers I don't see a reason of multipoint gre + NHRP with multicast mappings.The only thing I can think of is if you are asked to simulate broadcast over NBMA network.
Technically DMVPN is not a V4 topic. But if you take a look at v4 extended blueprint I even can't find things like Bridging, L2 tunneling, SSM, IGMPv3 too. So we never know :-)
