bird not exporting OSPF route

[Nico Schottelius]

Good morning,

after switching over to the following filter, as mentioned in the last
mails:

filter static_and_bgp_and_ospf {
  if(source = RTS_STATIC || source = RTS_BGP || source = RTS_OSPF) then accept;
  reject;
}

I still see routes that are missing in the kernel, even though they are
coming in via OSPF and BGP:

(BGP can be ignored, the OSPF route is relevant)

Checking on the OS side, I see the local IPv6 address 2a0a:e5c0:2:a::a
on lo, but not the remote IPv6 address 2a0a:e5c0:2:a::b that should be added:

--------------------------------------------------------------------------------
[08:08] server122.place10:~# ip -6 r | grep 2a0a:e5c0:2:a
2a0a:e5c0:2:a::a dev lo proto kernel metric 256 pref medium
[08:08] server122.place10:~# ip route get 2a0a:e5c0:2:a::b
RTNETLINK answers: Host is unreachable
[08:17] server122.place10:~#
--------------------------------------------------------------------------------

What am I doing wrong here?

And is there actually a CLI syntax for
verifying that a route is accepted by a filter? In case of this
particular filter there are a lot of matches, so displaying them and
checking is not really feasible.
