	actually, you may use it with two POPs of a single ISP too.
	if they do not aggregate per-POP you can use a single prefix and
	advertise routes normally.
	if the upstream ISP aggregates per-POP, you may get two /48 from
	them and operate these two prefixes (the scenario is closer to
	two different ISP case).
