This code doees this: a) Imagine ospf installs a route into zebra. Zebra crashes and we restart FRR. If we are using the -k option on zebra than all routes are re-read in, including this OSPF route. b) Now imagine at the same time that zebra is starting backup ospf on a different router looses a link to the this route. c) Since zebra was run with -k this OSPF route is read back in but never replaced and we now have a route pointing out an interface to other routers that cannot handle it. We should never allow users to implement bad options from zebra's perspective that allow them to put themselves into a clear problem state and additionally we have *absolutely* no mechanism to ever fix that broken route without special human interaction.
