I wouldn't redistribute and you don't have to, but I would advertise a
default network down at that level. I appreciate the response but it still
does not answer my question. The use of private AS's and Legal AS's : I
read (or so I thought. I will refer back) using both is an illegal design. I
think it can be done because Cisco's implemetation of BGP strips private
AS's when peering with a legal AS. So in theory my legal AS should strip off
the private before advertising it out to the ISP. This looks like a lab to
me. Thanks again.
