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
