It might work if you have a simple two router network, but if you have
a hub-spoke topology with more than one spoke, you will find that LSA
database in those routers are not consistent.
In NBMA mode a DR needs to be elected, but hub can not forward
multicast packets from one spoke to another spoke, hence DR can not be
elected automatically, the only option is to designate hub as DR by
using neighbor command.
