Use a newer kernel, or a different bond mode. The active/passive mode works well with IPv6, however most Round-Robin modes don't work in that kernel. I think 2.6.22 (or may be 2.6.23) has a fix for some of the bonding issues with IPv6. The trouble is that the DAD probe arrives back to us over the other bonded interface and causes issues. -vlad > > Setting net.ipv6.conf.eth-left.autoconf = 0 and > net.ipv6.conf.eth-right.autoconf = 0 would resolve the issue? > > Thanks, > > > Janos Mohacsi > Network Engineer, Research Associate, Head of Network Planning and Projects > NIIF/HUNGARNET, HUNGARY > Key 70EF9882: DEC2 C685 1ED4 C95A 145F 4300 6F64 7B00 70EF 9882 > _______________________________________________ > Users mailing list > Users@ipv6.org > https://lists.ipv6.org/mailman/listinfo/users > _______________________________________________ Users mailing list Users@ipv6.org https://lists.ipv6.org/mailman/listinfo/users
