All very good points. :) I suppose I should have picked "advertise into
protocol X" as my examples... I was just messing around in ospf when I
thought of the question. :)
So they typically do not allow you to use the "ip ospf X area Y"
interface command? I guess that would be a little too easy. :)
Cheers,
Jason
