Hi David,
My concerns about prop-101 is not address consumption but
route aggregation,
I am afraid the popular use of portable assignments will make route aggregation less possible. "2000 addresses or 200 /64s" seems to serve the
'conservation' purpose, but not the 'aggregation' purpose,
I think we can explicitly define the situations where renumbering will result in a significant impact, which cannot be aviod technically. Regards
Terence
