Yes but when using "up" and "down" you need to explicitly specify the
full command to use. In this case that means something (from memory)

iface eth0 inet static
	up ip -6 addr add 2001:8b0:3a9::101/48 dev eth0
	down ip -6 addr del 2001:8b0:3a9::101/48 dev eth0

You probably also need to add an "ip route add default dev eth0" for
each as well.
