Hi,
I have configured openbgpd on openbsd 4.0 (upgraded from 3.8) and there
seems to be problem with IPv6. I have tried google and irc, but without
success.
I am receiving IPv6 prefixes just fine (791 from upstream transit, 140
from local IX), but they are not exported to kernel routing tables.

As you can see this includes only IPv6 on local interfaces and loopback
and link-local addresses.
And IPv4 is just fine:
# route -n show -inet | wc -l
208368
Configuration snippet:
network 2001:0678:1::/48 set { localpref 200, community 6695:6695 }
group "de-cix-upstream-ipv6" {
remote-as 6695
announce self
enforce neighbor-as no
announce IPv4 none
announce IPv6 unicast
neighbor 2001:7F8:0:5:____ {
descr "DE-CIX-IPv6-UP1"
softreconfig in yes
}
neighbor 2001:7F8:0:5:____ {
descr "DE-CIX-IPv6-UP2"
softreconfig in yes
}
}
group "de-cix-ipv6" {
remote-as 6695
announce self
enforce neighbor-as no
announce IPv4 none
announce IPv6 unicast
neighbor 2001:7f8::____ {
descr "DE-CIX-IPv6-R1"
softreconfig in yes
}
neighbor 2001:7f8::____ {
descr "DE-CIX-IPv6-R2"
softreconfig in yes
}
}
Other notes:
- my network is exported just fine.
- I can ping6 on local ipv6 networks on external interfaces just fine.
Any clues, hints, questions?
