ospfd interface flaps / ospf process restarts

Trigonon Group
Hi BSD list,

I am having troubles stabilizing the ospfd at OpenBSD 6.2.

The neighbor relationship is between a Cisco Router and the OpenBSD box.

I am running iBGP between the two routers and ospf in a single area as the
IGP.

At random hours although the session seems stable the interfaces flap and
ospf neighborship is recalculated and restarted.

|CISCO ROUTER|   ----  | OPEN BSD BOX |


ospfd.conf:

router-id 10.20.88.4
redistribute connected

area 0.0.0.0 {
        interface bnx0
        }


bgpd.conf:
AS XXXX

router-id 10.20.88.4
network x.x.x.x/24

neighbor 10.20.88.5 {
        descr "ASR_TELIA"
        remote-as XXXX
        local-address 10.20.88.4
        set nexthop self
}

/var/log/daemon output:

I have also tried older version 6.0, 6.1, 5.9 with the same interface flaps.


ospfctl show neigh                                                                              
ID              Pri State        DeadTime Address         Iface     Uptime
10.20.8.5     1   FULL/DR      00:00:37 192.168.20.26     bnx0      00:44:14


# ospfctl show interface bnx0

Interface bnx0, line protocol is UP
  Internet address 192.168.20.25/30, Area 0.0.0.0
  Linkstate active, mtu 1500
  Router ID 10.20.88.4, network type BROADCAST, cost: 10
  Transmit delay is 1 sec(s), state OTHER, priority 1
  Designated Router (ID) 10.20.88.5, interface address 192.168.20.25
  Backup Designated Router (ID) 0.0.0.0, interface address 0.0.0.0
  Timer intervals configured, hello 10, dead 40, wait 40, retransmit 5
    Hello timer due in 00:00:08+773msec
    Uptime 00:47:55
  Neighbor count is 1, adjacent neighbor count is 1




Please help I have tried to keep the configuration files as simple as I can
with no success on stabilizing the ospfd process.

Thanks in advance
