solution guide shows neighbor statements and PTMP-NB for the solution.

Subject: RE: Doubt on OSPF hub and spoke IEWB 17 4.1
Hello
The issue is that they are not allowing me to change anything at
interface level on the spokes. So, to change from NBMA to p2MP(-NB) I
would need to do that. (I will not try P2MP-NB, because you need to
specify neighbors, which I can't)
If you are suggesting to put P2MP on Hub and let spokes on NBMA, I am in
process of trying it.
For what I can see the adjacency is established, but there is no route
exchange.
I'm still at a dead end :(
Thank you for replying

Have you tried point-to-multipoint non-broadcast? See if you establish
adjacency after that...I think the key here is that you are using
physical
interfaces and you cannot adjust anything on the spokes. PTMP-NB should
do
the trick unless there's something I'm missing here.
