In the book, hub subinterface is specified as point-to-point, by befault
point-to-point subinterface has OSPF network type point-to-point.
However, on the spokes, subinterface's type is not define explicitly, which
is not possible. After I enable encapsulation frame-relay on physical
interface, if I want to creat subinterfaces, I always needed to specified
point-to-point or multipoint.
The book didn't and that is why I think it is a mistake in the book.
Also, no "ip ospf network" command is used, so default OSPF network type
applied.
