Hi Need some help debugging some OSPF issue. I have some flapping on the data center network Bascially I have a backbone with 1 asa5520 4 CCR1036 4 RouterOS VM's I am using OSPF to get the routing done. After the issue in the morning I turn on ospf,debug,!raw to my syslog server. To see if I can find out what the issue was This seems to be unusual behaviour (I think), doesn't normally happen, seem to be re inserting known routes but with a different seqnum ?

Alex, the first thing I would be doing is fixing the authentication failures, Mikrotiks do behave strangely sometimes with OSPF I have found and occasionally need a kick in the butt, but in general it works well. Are you running recent versions of RouterOS everywhere and are they all the same version ?

The network is not being overly used ... If somebody can tell me if this is normal behaviour ... "install and flooding". Or its normal for when seq numbers get out.. What might be things that might through a seq out ? Also the network is very static.. so ... I have actually gone in and add static routes with metric 250 for 90% of the routes..
