Dear Jouni and others, When I changed the routing entry of my linux box (Redhat 6.2), it takes around 2 seconds before the traffic gets routed to the new path... I read through the mailing list and tried the following methods without luck: - set the values of min_delay and max_delay at /proc/sys/net/ipv4/route to be zero - use the command "ip route flush cache" - echo 1 > /proc/sys/net/ipv4/route/flush It seems that even though I manage to flush the routing cache successfully, the traffic still does not follow the new path in the FIB routing table until a few seconds of time delay??! I would appreciate so much if someone could assist me with this issue... Thanks in advance... Jonathan - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
