Running Routing Protocol over 6to4 Tunnels

I'm wrestling with running a routing protocol over 6to4 tunnels. I can ping
from tunnel end point to end point, but can't get to any other 2002::/16
addresses I've created. That was based on the static route 2002::/16 out
the tunnel interface. So I am trying a dynamic routing protocol, OSPF in
p-mp nbma mode. I have configured the neighbor statement so there's a next
hop address, but I don't get a neighbor relationship.

When pining the other end of the tunnel I actually see icmp traffic. But
when I ping another 2002 address I don't see anything. I have the static
2002::/16 tunnel 345.

So my static didn't work and neither did a dynamic protocol to get to 2002
addresses other than the tunnel end points.

What am I missing?

Topology: R3, R4 and R5 are set up with 6-to-4 tunnels.
