Hi again. I have problem with ipv6 slaac address on my servers with
fedora 28 (4.16.14-300.fc28.x86_64).
server 1:
link/infiniband
80:00:02:08:fe:80:00:00:00:00:00:00:00:21:28:00:01:a0:99:bd brd
00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
link/infiniband
80:00:02:09:fe:80:00:00:00:00:00:00:00:21:28:00:01:a0:99:be brd
00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
server 2:
link/infiniband
80:00:02:08:fe:80:00:00:00:00:00:00:00:21:28:00:01:a0:cf:e1 brd
00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
link/infiniband
80:00:02:09:fe:80:00:00:00:00:00:00:00:21:28:00:01:a0:cf:e2 brd
00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
On server 3 with subnet manager i'm install bird and send ra: 2001:db8:1::/64
server 2 succeseful configure ipv6 address, but server 1 not.
messages from server 1:
[1372976.977527] ICMPv6: RA: ndisc_router_discovery failed to add default route
[1372977.632880] IPv6: bond0: IPv6 duplicate address
2001:db8:1:0:8200:2ff:fe09:fe80 used by 00:00:00:00:00:00 detected!
because on all ib devices hw address begins with:
80:00:02:09:fe:80 (8200:2ff:fe09:fe80 in slaac)
how to fix this issue and get ipv6 slaac to work with infiniband ipoib?
Thanks!
