Point: there's a body of data that indicates "multihoming" is not the
culprit. There's a lot of needless de-aggregating that has little or
nothign to do with multihoming, and mostly to do with lack of clue.
Both WRT limiting the scope of provider-based so-called "traffic
engineering" (CF ptomaine drafts) and that folks not using large tracts
of space can return blocks and get blocks that actually *fit* their
need.
Unfortunely there's a few companies/consultants whose business plan
requires them to graze on the commons and get all in a huff when any of
us tell them they're filtered because they are causing incremental damage
to our networks. Get over it kids; stable and deterministic behavior is
required for IP to work optimally.
Stability uber alles,
Joe
