Mike,
If you can give more details in the future like debug output your running configs we may be able to help more. I didn't experience this problem when writing the lab so I am not sure without more details. Let me know if you re-try and what your results are.

I could not get ospf over the dmvpn to stabilize at all. I have been trying for 6 hours.. It just flaps up and down and I don't get any routes between R2, R4, R5 and R6 - which renders the whole lab useless. Has anyone had the same issue? I have tried adjusting the serial interfaces and allowing broadcast etc, but ospf comes up for 5 mins then goes down again. Any help would be appreciated.
