You have only to choose first it two tunnel interface for each spoke.
Second solution full mesh.

Subject: RE: ISIS Hub and Spoke over Frame-Relay NBMA
Hi to All,
I was too quick to delete the original email so I don't know
who initially posted the question. But I setup the scenario
in my home lab and the answer is yes, ISIS over NBMA
hub and spoke will work. The problem stated that the hub
could see all the spokes ISIS routes but the spokes could
not see the other spokes ISIS routes. I played with changing
the ISIS type on the hub, then on the spokes to no avail.
The final answer was to have the hub originate a default route!!!! I could
not
find any documentation on this type of
setup. Don't know if this is the proper solution but if this were a
production
setup it would work . The following is the
scenario and the pertinent configs of each router.
