	per machine I would say.  Noone is doing it in per-interface basis.

	Is your "external" network shared medium, or p2p? (I'm novice about
	what PPPoE look like)  If p2p, you do not need global address for
	external network.  If you have link-local address on external
	interface, route6d can exchange route just fine.
	Even if it is shared medium, if you have no neighbor other than
	router on external interface, route6d may work without global address
	(not tested recently but should be okay).

	For internal address, apparently you don't need to/want to reconfigure.
