From a5361886ac6d7b0b72ea5765b175a96a4521dc2a Mon Sep 17 00:00:00 2001 From: "David Kaspar [Dee'Kej]" Date: Mon, 10 Jul 2017 18:16:35 +0200 Subject: ARPUPDATE introduced The ARPUPDATE option has been introduced. It defaults to 'yes'. By setting the ARPUPDATE to 'no', administrator can disable updating neighbouring computers with ARP information about current NIC. This is especially needed when using LVS Load Balancing with Direct routing enabled. --- sysconfig/network-scripts/ifup-eth | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysconfig/network-scripts/ifup-eth') diff --git a/sysconfig/network-scripts/ifup-eth b/sysconfig/network-scripts/ifup-eth index 3da5c16b..5096a5d8 100755 --- a/sysconfig/network-scripts/ifup-eth +++ b/sysconfig/network-scripts/ifup-eth @@ -274,7 +274,7 @@ else fi # update ARP cache of neighboring computers - if [ "${REALDEVICE}" != "lo" ]; then + if ! is_false "${arpupdate[$idx]}" && [ "${REALDEVICE}" != "lo" ]; then /sbin/arping -q -A -c 1 -I ${REALDEVICE} ${ipaddr[$idx]} ( sleep 2; /sbin/arping -q -U -c 1 -I ${REALDEVICE} ${ipaddr[$idx]} ) > /dev/null 2>&1 < /dev/null & -- cgit v1.2.1
