FRR OSPF sendmsg in ospf_write failed to 224.0.0.6

[andreib]

Hi, there seem to be some problems with FRR OSPF, when installed for the first time (the FRR package) after configuration, it all works fine. After a reboot of the system, the OSPF instance stops working and I get this messages in logs:

I have allowed OSPF traffic in the fireall rules, also in (FRR) Routing > General - the option "Firewall Rules" is enabled. This seems to be a bug since it works fine the very first time it is installed and configured/enabled. After reboot... doesn't.

Any idea?
