That and the "I have 1 circuit to $good_provider and 1 circuit to $bad_provider and the only way I can make them balance is to split my space in half and announce more specifics out through each provider" argument. I have also often seen people do this without announcing the aggregate because <some undefined bad thing> will happen, usually justified with much hand-waving. The people who do this can usually not be reasoned with....
So, say I'm a provider that has received a /22 from UUNet (just for example Chris :-) ) and I now get another transit provider and announce the /22 there. So, I call UUNet and ask them to announce the /22 as 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<

[ hint, hint ]
The BGP tutorials I've been doing on Sundays at NANOG all cover aggregation - at least, I seem to end up talking about aggregation in each one. Maybe I need to be more direct? But then again, who am I preaching to? The choir maybe, I don't know. Maybe we need a specific aggregation tutorial for those who don't know how to? Those who have operational and technical reasons not to aggregate have made that decision with prior knowledge. We should try and give everyone else the knowledge, then at least we will know that all de-aggregation is done for a reason. Then it begs the question, is NANOG the conference actually reaching the people who'd most benefit from it? I say this as I'm in transit in Singapore heading back from a hugely successful and enjoyable SANOG (South Asia NOG) in Bangladesh. Similar idea to NANOG, but heavier emphasis on education (workshops & tutorials), and we had ISPs falling over themselves to participate in the first Internet operations meeting held in that country. philip --

But there are hundreds of ISPs out there who don't have a clue. RIPE realized this without having to do a membership poll and rightly so, goes and does training where it is needed (and believe me - I am their biggest critic and all-around pain in the ass when it comes to their expenses as Leo and Rob can attest). NANOG is not the place to do it. ARIN, as part of their overhead should do an east coast, west coast and Chicago area tutorial at least once a year. And guess what - most of the training material has already been written by the other RIRs. -Hank
