Dynamic routes from OSPF disappear

[Gregor Kališnik]

Hi.

We have two routers and 7 machines with bird installed (7 machines <-> router 
<- Internet -> router <-> 8th machine) that work without problems. When I've 
added 8th machine with Ubuntu 14.04 and bird 1.4.3, everything was working for 
about one hour after all routes announced over OSPF disappeared, also own 
routes were not announced.

By enabling debugging (debug ospf1 all in birdc) there are no messages that 
would indicate an error (just normal hello exchange and OSPF LSA 
announcements). By restarting the ospf1 protocol, the OSPF routes are 
exchanged and it works for another hour or so.

Anybody experienced the same behavior?

Best regards,
Gregor Kališnik
