(traffic engineering given the '1 prefix per ISP' standard mantra)AS path prepending, local preference, that kind of thing...Common practice with IPv4 seems to suggest that those knobs aren't sufficient in real life; people still find it necessary to carve up their aggregates and announce more-specifics in strategic directions. I would suggest that not *all* observed instances of such deaggregation are due to operator ignorance :-)
I think this goes back to my point about DHCP, today there is a business practice and set of business requirements that work for a host of reasons. Expecting that in v6 these requirements will evaporate is not wise. There will have to be some useful TE knobs, I think the operations community would probably like to see those knobs NOT be 'deaggragate' so what other options are there for someone with a single prefix (especially when that prefix is very large). -chris
