Hi, after upgrading from squeeze to wheezy one of our servers has problems with additional IPv6 addresses on a bond interface. Each IPv6 address which is added is marked as dadfailed.
The behavior looks similar to this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=503082 My network configuration looks like this (reduced, there are multiple VLAN interfaces on the bond): auto bond0 iface bond0 inet manual slaves eth0 eth1 bond_mode 802.3ad auto bond0.1010 iface bond0.1010 inet6 static address XXXXX::b:2 netmask 64 If I try to add a additional address to bond0.1010 the following happens: ip addr add XXXXX:100/64 dev bond0.1010 ip -6 addr show bond0.1010 7: bond0.1010@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 inet6 XXXXX:100/64 scope global tentative dadfailed valid_lft forever preferred_lft forever inet6 XXXXX::b:2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::XXXX/64 scope link valid_lft forever preferred_lft forever During the add command I see the following in tcpdump: 11:47:32.601411 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 4 group record(s), length 88 11:47:32.601522 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 4 group record(s), length 88 11:47:32.857288 IP6 :: > ff02::1:ff00:100: ICMP6, neighbor solicitation, who has XXXXX:100, length 24 11:47:32.857442 IP6 :: > ff02::1:ff00:100: ICMP6, neighbor solicitation, who has XXXXX:100, length 24 11:47:34.473288 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 4 group record(s), length 88 11:47:34.473444 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 4 group record(s), length 88 If I add the address when the second interface is down, everything works ok: ip link set eth1 down ip addr add XXXXX:100/64 dev bond0.1010 7: bond0.1010@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 inet6 XXXXX:100/64 scope global valid_lft forever preferred_lft forever inet6 XXXXX::b:2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::XXXX/64 scope link valid_lft forever preferred_lft forever With one interface down, I see the following packages in tcpdump when adding the address: 11:48:00.749287 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 11:48:02.405459 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 4 group record(s), length 88 11:48:03.177233 IP6 :: > ff02::1:ff00:100: ICMP6, neighbor solicitation, who has XXXXX:100, length 24 11:48:04.185285 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 5 group record(s), length 108 11:48:06.749287 IP6 fe80::XXXX > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 There is only one neighbor solicitation package instead the two above. I'm not sure if this list is the correct destination for this issue, but maybe someone could point me to the right list if not.
