(It may be, but this is an implementation decision.) Regarding CPU, remember that you want to optimize the bottleneck, nothing else matters really. In most cases, the RR is the control plane bottleneck. Loading it up more to protect the CPUs of non- bottleneck devices seems like an odd design decision. >> IMHO based on the most common implementations at that time that was >> the >> main reason for the RR spec change. > > "Implementations" should be "implementation" there, not the > plural.

As we've discussed already. I don't think this point is any different? --John _______________________________________________ Idr mailing list Idr@ietf.org https://www.ietf.org/mailman/listinfo/idr
