Not quite - the way to do it is to not use Stub areas. One way is NSSA,
but you can also do it within a core area. Stub areas are the one area
type with restrictions.

I think you could do that, configure it as a transit and not a stub or

I think that is changed in 3.8. It was tied at compile time to BGP -
so the IRX and PM-3 have it, the others don't. But that isn't necessary,
it can work on any unit. It was just the way it was lumped into ComOS
when it was added. We've been asked about it a few times, and myself
and others want to see it changed. I think 3.8 will have it for all
the units.
