Can someone please reiterate to me, from experience, reasons why a prefix
shouldn't be advertised as originating from two separate ASs?  I think 
this is a bad thing and I understand that by advertising the prefix from 
two separate ASs there is no way to distinguish the policies of that 
prefix.  But, in today's Internet, does anyone have any experience with what 
kind of problems this equates to, so that I can forward them on to the 
appropriate people.

I have a site that I am trying to convince that this is a bad thing and I
would like some support.  The customer is a dual-homed site to provider A
and provider B, but doesn't want to run BGP (fear of routing protocols I
guess), rather just wants their prefixes advertised in both provider A and
provider B ASs. 

Thanks.

-Chris
