I have also often seen people do this withoutannouncing theaggregate because <some undefined bad thing> willhappen, usuallyjustified with much hand-waving. The people who do thiscan usuallynot be reasoned with....So, say I'm a provider that has received a /22 from UUNet(just for exampleChris :-) ) and I now get another transit provider andannounce the /22there. So, I call UUNet and ask them to announce the /22as a more specific Meaning you have PA space from UUNET, and you have BGP so you can multi-home... I'd expect you to know how to deaggregate yourself. You MIGHT even know how to send no-export on deaggregated prefixes, or use the 1996 policies to influence preferences/prepends internal to 701, yes?
Is aggregation being covered in the Sunday BoF's? [ hint, hint ] -M<
