If you have provided addressing from your aggregate to your customer and they have indicated that they are multi-homing, you need to preserve their prefix-length in your outbound advertisements, or the redundant provider carries the inbound traffic. Is this also frowned on? To me, this is the multihoming tax we all pay for. Paul
Someone multihoming below you on PA space is a pretty special case (part of why I said generally above actually), but definately one I would consider valid as for passing the announcements through from their AS. -Blake
