@Joni, its almost as if the MikroTik community forums aren't an official tech support method hey?
MikroTik have stated several times that they don't monitor this forum closely as its a user forum for users to discuss amongst each other. Maybe you have noticed that when MikroTik staff do participate in the forums, they will encourage people having bugs or other misbehaviours to log a support case?
Even if they did see this thread I am curious how you think they are supposed to solve it when nobody has shared any particularly detailed information about their setup or what they are seeing, let alone a supout file (one of the first steps of logging a support case).
So if you just want to sit around and feel sorry for yourself that's fine and you have my sympathy. But its been nearly 2 years doing the same thing without any results, so maybe its time to try another way?
BTW to add something productive to the discussion: I am having the same issue with CCR1036 running 7.12 (also seen in 7.11 and 7.10) speaking OSPF with CCR1036 running 6.48.6
While the OSPF adj does form, I get the following log message:
default-v2 { version: 2 router-id: 10.200.199.131 } area10-v2 { 0.0.0.10 } interface { p2p 172.23.253.9%VLAN18 } neighbor { router-id: 10.200.199.130 state: Full } received wrong LS Ack for router 10.200.199.131 10.200.199.131 0x80001186 expected 0x80001187
I have firewall filter rules but no NAT. Connection tracking was auto, however no change when I set to no.
I will advise the case ref when I log it.
