Hello! > Isn't that what route dampening is for? The routing daemon would handle > this situation to avoid the total breakdown. It prevents overload _while_ daemon loads updates to kernel. 2 seconds is just minimal value which is absolutely safe, because route updates are delayed in any case. "ip ro flush cache" is used to complete some kinds of updates, which are not flushed automatically. F.e. in batched scripts changing policy rule, when you want to be sure that cache will be flushed but do not know forward, when batch will be completed. What's about immediate flush, you can request it with: echo 0 > /proc/sys/net/ipv4/route/flush ip ro flush cache is equivalent to: cat /proc/sys/net/ipv4/route/min_delay > /proc/sys/net/ipv4/route/flush Alexey - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
