hello,

I have a problem with OSPF between SE100 and FreeBSD.
Before, there was FreeBSD(openospfd)--Linux(quagga) working fine.

FreeBSD:
#########
wan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
        ether 00:15:17:25:f6:5d
        inet6 fe80::215:17ff:fe25:f65d%wan0 prefixlen 64 scopeid 0x1
        inet 195.66.73.174 netmask 0xfffffff8 broadcast 195.66.73.175
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
