The easy answer is that there is trash in the IRR. When looking a little
closer or talking about a well-run source DB consider the consolidation 
of multiple ASNs, customers getting their BGP training wheels, etc other
typical origin changes. To smooth over any origin changes, it makes
sense to get route objects in at least a day or two in advance; if you're 
doing large scale projects long-term overlaps are not at all uncommon.

If you think of the IRR as a 'flight plan' or the list of "intended
possibilities" then it makes more sense than trying to treat it as a
strict tracking of the live BGP table state. The latter would bring you
nothing but woe.

Cheers,

Joe
