Hi Friends, I am having some trouble in understanding the linux arp cache behavior. Whenever a reachable neighbour is switched down, the corresponding neighbor state moves to STALE. This gets triggered after every gc_stale_time interval. What I wanted to know is that when does the entry get deleted/aged-out from the kernel arp cache. I have observed that this entry stays there in the arp cache for around 6 mins, am I missing something? Is there any ageing timeout value that needs to be set to age out STALE entries? I have tried setting gc_interval, gc_thresh1 to 1, but even then it seems that the garbage collector does not kick in. Looking forward for some helping hand. Thanks, Partha Chatterjee. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
