	8 seems excessive - are you doing BGP with all of them ? Is that 8
	different providers ?

	Or are you doing, say, 4 upstream providers with 2 links to each
	(failover) ?

	Short of disaggregating and announcing smaller pieces of your prefix
	to your upstream, I don't think so. Other solutions are usually technical
	hacks like MLVPN or only work for downstream traffic.

	Anyway, there are more qualified folks on this list to give better
	suggestions :)

	Cheers,
