The problem is that when a nexthop becomes unresponsive we need to wait for an event to timeout the routing cache entry. In 3.6.0-rc1 and later, this inconsistent behavior will happen less often, because the routing cache has been removed so we will do the full default route resolution on every route lookup. The only problem at that point is socket cached routes, those will still need to wait for a timeout before the next default gateway will be tried. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
