ospf not started between microtik and cisco

RouterOS Forwarding Protocols
1

Hello all. Sorry, I’m newbie in microtik. I try to add microtik to cisco ospf community. I have added instanse and networks. But there are not any neighbors. In log of web control there are only strings “OSPFv2 interface changed by admin” or “OSPFv2 network changed by admin”, no more details. On all cisco boxes microtik neighbor is with status INIT :

172.30.0.10       0   INIT/DROTHER    00:00:33    10.0.2.31       GigabitEthernet0/1

In cisco ospf debug there are not bad messages. Only

Dec 22 10:16:34.232: OSPF: Rcv hello from 172.30.0.10 area 0 from Vlan785 10.0.2.31
Dec 22 10:16:34.232: OSPF: Send immediate hello to nbr 172.30.0.10, src address 10.0.2.31, on Vlan785
Dec 22 10:16:34.232: OSPF: Send hello to 10.0.2.31 area 0 on Vlan785 from 10.0.0.1
Dec 22 10:16:34.232: OSPF: End of hello processing

MIcrotik 951Ui-2HnD firmware 3.16.
What’s wrong? Thank you.

Hi

What do the logs on the MIkrotik say?

If you don’t have OSPF logging enabled you can do this in System → Logging

/system logging add topics=ospf action=memory

you can then follow the log on the console using /log print follow

or view it in the web browser

You may find you have an MTU mismatch (the Mikrotik will report this in the logs) or otherwise it could be a timing issue or some other mismatch.

If the ordinary ospf logs aren’t enough you can also add debug to get really verbose chatter about what is happening

Thank you very much. In logs I found no “received” strings and add firewall rule. Excuse me for dummy question.

Thank you very much. In log I found only send string, without received. I add firewall rule and now it works.
