Thanks a lot for sharing. So 100 Gbps at line rate with 80B frames is about ~150 Mpps. 100 Gbps at line rate with 208B frames is about ~60 Mpps. It's a significant penalty.
Full rate small packets would be an attack of some kind and could only realistically arrive at your transit and peering ports. The customers usually have slower (relatively) ports and a single customer could not produce a rate of small packets that would be a concern. Therefore uRPF at customer ports should not be a problem in this regard. Regards, Baldur
