Hi Peter,

What am I missing? The last few times this was discussed here or on
RRG, RIB aggregation fell apart on the details. For example, what
happens when:

AS1 announces 10.1.0.0/16 from network A via ISP 1 and 2
AS1 announces 10.1.33.0/24 from network B via ISP 3 and 4

If the answer is: AS1 disaggregates 10.1.0.0/16 in order to avoid
overlapping 10.2.33.0/24 because at least a couple folks implementing
overlapping-routes broke network B then what is there to discuss?

Regards,
Bill Herrin
