After hours server 2 drops ipv6 address and have in dmesg only IPv6: bond0: IPv6 duplicate address fd00::8200:2ff:fe09:fe80 used by 00:00:00:00:00:00 detected! server 1: have ipv6 slaac address assigned and no errors in dmesg. I think that who first get ipv6 address wins and second have error. I'm disable DAD and now server 1 and server 2 have identical ipv6 slaac addresses. And i know that this is not bird problem and not dnsmasq problem because in case of plain ethernet devices with normal hwaddres this issue not happened. -- Vasiliy Tolstov, e-mail: v.tolstov@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
