Hi

Non-stub ptp addresses are not propagated by design based on assumption
that in many cases you either don't want them to be propagated or are
propagated anyways as 'loopback' /32 addresses. And it is generally
easier to add stub address when necessary than remove them when unwanted.

But i admit that this is counterintuitive and sometimes impractical and
we should have some configurable option to handle it, with default to
distribute them.
