RE: Newbies Question: Do I really need to sacrifice Prefix-aggregation to do BGP Load-sharing? (the case of Multi-homed + Multi-routers + Multi-upstreams)

I imagine it's an ISP you are talking about, where the traffic is mostly inbound. Hire transit companies that have good traffic engineering community policies. - Selective prepending or seletive no-export by: -> Type of peer. -> Geographic location of their routers. -> ASN specific. And then you
