Hi

It is likely got broken by commit introduced OSPF graceful restart
(commit 1a2ad348f660b150265f6df759a07de8a2b6de2f). Could you verify
that by checking before and after that?

There is a tricky part in OSPF code that is responsible link-back
calculation that had to be tweaked for OSPF-GR, so perhaps it failed for
link between 10.210.139.1 and 10.210.139.5, so it was not used for
routing table computation.
