Hi Ondrej
But unfortunately the problem with neighbor state remaining in "exchange" seems to be another problem. In this case I don't see any LSA packets, only hello packets.
Yes, that is probably completely different problem. But you should see at least some DBDES packets when neighbor state became "exchange". If you have enabled logging of events and packets, these should be in BIRD log (messages like "DBDES packet received from"). Could you send me that part of log?
Hm, one time I had the problem with "exchange" again, but since then not anymore. Perhaps there was another problem in the environment.
If one side is stuck in "exchange" state, what is the state of the other side?
In this case, the other side has the state "full". With your latest patch everything seems to be fine now. I would let you know the problem apears again. Thanks for your good work. Best regards Elmar
