Hi Roni,
The problem here would be that the "spoke" routers would not see any other "spoke" routers on the NBMA network as neighbors. Therefore, when building the routing table, these routers would not install any routes that have as next-hop a router that is not on the list of neighbors. If you looked in the ISIS database, you would see that all required LSPs are present. However, your routing table would have missing routes.

Hi guys,
I read some lab material that sated that routers in the same subnet on a
NBMA network have to be directly connected to each other for ISIS to
work properly; hence they must be fully meshed. I thought what really
matters is who the DIS for the network is, and so this would work fine
on a hub and spoke too by increasing the priority of the hub router. Can
someone please clarify?
Thanks,
Roni.
