Hi Brian,
I had also responded to this question a little earlier and provided the same
answer. But, I tried to take the answer a little further with an explantion
and example of why the as-set attribute is used and mentioned the
possibility of routing loops. At that point, it occurred to me that even if
the aggregate is advertised back to an AS from which one of the more
specific routes that comprised the aggregate has come, there shouldn't be a
routing loop problem because of the longest match rule.
Do you know what I'm missing in my thnking? Thanks, Jim
