Hi

The stubnet option is targeted on cases, where stub prefix is not
directly related to an iface, e.g. an aggregate stub network covering
multiple ifaces. It is an analogy of 'networks', just on node level
instead of area level.

If you want just stub network based on iface prefix, then just define
stub interface:

area {
  interface "ethX" { stub; };
};
