Hi, I see in ifup-ovs that the following is done: OTHERSCRIPT="/etc/sysconfig/network-scripts/ifup-eth" ... ${OTHERSCRIPT} ${CONFIG} which should call ifup-eth and update the neighbours if a static IP is set Indeed initscripts already advertize the IP to neighbours root@rhel7:~# strace -feexecve ifup ovsbr0 2>&1 |grep arping [ 914.376268] device ovs-netdev entered promiscuous mode [ 914.379838] device ovsbr0 entered promiscuous mode [pid 11311] execve("/sbin/arping", ["/sbin/arping", "-c", "2", "-w", "3", "-D", "-I", "ovsbr0", "192.168.240.1"], [/* 20 vars */]) = 0 [pid 11313] execve("/sbin/arping", ["/sbin/arping", "-q", "-A", "-c", "1", "-I", "ovsbr0", "192.168.240.1"], [/* 20 vars */]) = 0 [pid 11381] execve("/sbin/arping", ["/sbin/arping", "-q", "-U", "-c", "1", "-I", "ovsbr0", "192.168.240.1"], [/* 20 vars */]) = 0 I close the bug for now, reopen if you have evidence that gARP are not sent. |
