Re: Customer AS

In my (rather extensive) practice, multihoming by itself is usually a major source of connectivity problems. Whoever arguing _for_ mulihoming for everyone forgets that taking more routing information in has dangers not present when you don't do routing yourself. I never saw any customer who had the ability to configure a multihomed site properly on their own; and most of the bogus routing information comes from multihomed customer sites. It is _much_ better to multihome to the same provider who then can take care of messy global routing. --vadim PS A UPS for CPE usually fixes 95% of transmission problems. I've seen people willing to spend money on multihoming but doing things on commercial power.
