Perhaps you meant https://tools.ietf.org/html/rfc3484; and even by that RFC, the "longest-matching prefix" rule 8 would prevent ULA from being selected over GUA as the outgoing address for connection to a GUA IP in case when the node has both (as in the situation we're discussing now), since fc00::/7 has zero matching leading bits with 2000::/3. -- With respect, Roman -------------- next part -------------- A non-text attachment was scrubbed...
