just how bad is the auto-summarization at the upstream for the route propagationWhat auto-summarisation?
If you're talking about the cisco "auto-summary" command, then the answer is "so bad that it's universally disabled" (but then "auto-summary" is concerned with aggregation on pre-CIDR, classful boundaries which I don't think is what you were talking about).
Absent a precise understanding of all the routing policies concerned, proxy aggregation is dangerous and is hence generally not done.
