Forgot to answer this one point...
Combined interface stats aren't very useful for a scenario we commonly
entertain: what will happen if I move Big Customer A's ingress to ANSnet
from ANS border router X to ANS border router Y? I need to know who
they're talking to in order to answer that question. Typically large
portions of the ANS mesh will be affected, and I need to know how.
