Hi I'me running a couple of openbsd routers running (still OpenBSD 6.0) with carp failover and ospfd+ospf6d. Everything seems running fine but i see clockwork every 5 min the following message:
ospfd[PROCESSID]: desync; scheduling fib reload ospfd[PROCESSID]: reload interface list and routing table It appaers from source/docs that RTM_DESYNC could com from buffer shortage. We have changed default sysctl settings for: kern.maxcluster=24576 net.inet.ip.ifq.maxlen=4096 net.inet6.ip6.ifq.maxlen=1024 as from netstat -m we ran out of 2048 mbufs at defaults. We run 4 10gb ix interfaces for traffic one uplink and 2 bound as trunk (failover) and carp on the vlans on top of the trunk. ospf is simply announcing connected carp and flagged routes. Where can I get more information how to tune ospfd so desync won't occure. For now upgrading to 6.2 is not a option. We had issues with 6.1 and our ix interfaces not being enabled. See mail in this list from may 2017. Any input would be helpfull Regards Robert
