I hear you guys, It's done that way for a bit of traffic steering. If I could get away with just the aggregates I would, Trust me.

That should be unnessecary, the local prefs should already be winning as a customer vs transit/peer for equal prefix length. As an aside, generally inbound traffic steering as a reason for disaggregation is fairly frowned upon by the community at large as it effectively makes everyone else pay more in additional hardware cost for your savings. -Blake 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
