Hi Jakob,

I assume that new SAFI is "informational" what really means that during
client bring up time it has no dependency to real AFs (1/1 & 2/1) best
paths on the client.

Your point is correct when you assume that the best path RS sends out is a
bad one which is sort of unlike if one follows John's suggestion to based
best path selection for client A based on the feedback from other clients
B-Z. But I already expressed my opinion on such scheme ....

Cheers,
R.
