https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219699 Bug ID: 219699 Summary: Issue with IPv6 and neighbor notification Product: Base System Version: 11.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: standards Assignee: freebsd-standards@FreeBSD.org Reporter: paul.g.webster@googlemail.com I will be honest here and admit that I do not know quite if this is that FreeBSD is doing IPv6 right and linux is implementing some hack to get around a problem or if FreeBSD is doing something wrong. Its a little to low level for me, so I hope someone with a little more knowledge can clarify the issue. Ok so I grabbed a cheap VPS to run a small mail server on, it is XEN; all works lovely, virtio etc.. but for ipv6 the host implements a shared gateway for all its clients, notable: 2a07:4580:b0d::1/48 I have a /64 in my command on this range; 2a07:4580:b0d:27e::/64 for which I use 2a07:4580:b0d:27e::1/128 for my mail server. Now the issues; for me to reach that gateway from that prefix I needed to set: ifconfig_vtnet0_ipv6="inet6 2a07:4580:b0d:27e::1/48" ipv6_defaultrouter="2a07:4580:b0d::1" because obviously, my assigned /64 could not reach there gateway, from what I understand from the IPv6 folks I should be able to simply set the gateway to the interface without such a hack, but once again realistically; no idea. Now for the actual problem.. the ipv6 is spotty, 95% loss and what is going on is there gateway seems to believe I am not really using the address; if I do use it; it temporarily 'comes up', so I did this: $ cat /etc/rc.local daemon -f ping6 -i 2 -s 1 2a07:4580:b0d::1 and wallah perfect working ipv6, I assume that some sort of 'neigbhour notification' is not taking place, and the ping is enforcing it. But I also have several linux VPS's with these guys and they are all fine, hence my reason for calling out for help to figure out what exactly is wrong. -- Cheers paul -- You are receiving this mail because: You are the assignee for the bug.home | help
