I was wondering if it was possible to build a V6 DMVPN over a V4 network cloud.
If for example i have a simple topology with 3 routers 1 hub and 2 spokes. In the cloud is running OSPF. I could get tunnel IPV6 in IP but then i cannot tunnel into tunnel the DMVPN traffic right? Also the tunnel mode would be not p2p or p2m, it would be 6to4 or ipv6ip since it has to flow through V4 cloud , but like in everything there is always an exception. It is that the case? it is a possible scenario we should practice for the lab?
