This thread begs an interesting question: what is the right amount of granularity for load balance? Folks here are saying that one-entry-per-AS is too course...an AS wants to influence load on incoming links, and so it needs multiple entries.

On the other hand, it is hard to imagine that we need hundreds of entries per AS, or even dozens. So I'm curious...if we could wave a magic wand and control the exact number of entries any AS needs to advertise, what would folks consider to be roughly the right number of entries?

Thanks,

Although hard to imagine, I would think that flexibility would be desired for those willing to implement/manage it. *************************************************************************************** The information contained in this message, including attachments, may contain privileged or confidential information that is intended to be delivered only to the person identified above.
