Where are they documented ? So RTA_PRIORITY is actually the administrative distance / "metric" and numerically increasing values confer decreasing precedence on the route? How do RTAX_* interact with RTA_PRIORITY ? Reading rtnetlink.h / man rtnetlink(7) is not much use in answering these questions. -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
