BGP: can't set sockopt TCP_MD5SIG 0 to socket 16

[Nik]

 I'm using FreeBSD 5.4 with quagga 0.98.5. For L2 switch I'm using D-link
DES3326S and router using intel GB network card (dual port). The routing
process is controlled using quagga by ospfd and zebra. I forgot to see the
network traffice from tcpdump, for that I need to do a testing first and
will let u know the result.

Therefore, here is my vlan's config :

# --*Network*--
network_interfaces="em0 em1 em2 em3 rl0 lo0"
ifconfig_rl0="inet 192.168.0.10 netmask 255.255.255.0"
ifconfig_em0="up"
ifconfig_em1="up"
ifconfig_em2="up"
cloned_interfaces="vlan0 vlan1 vlan2 vlan3 vlan4 vlan6 vlan7 vlan8 vlan9
vlan10"
ifconfig_vlan0="inet xx.xx.0.1 netmask 255.255.255.0 vlan 1 vlandev em0"
ifconfig_vlan1="inet xx.xx.8.1 netmask 255.255.255.248 vlan 20 vlandev em0"
ifconfig_vlan2="inet xx.xx.1.1 netmask 255.255.255.192 vlan 2 vlandev em2"
ifconfig_vlan3="inet xx.xx.11.1 netmask 255.255.255.0 vlan 1000 vlandev em0"
ifconfig_vlan4="inet xx.xx.13.1 netmask 255.255.255.0 vlan 1001 vlandev em0"
ifconfig_vlan6="inet xx.xx.10.129 netmask 255.255.255.240 vlan 50 vlandev
em1"
ifconfig_vlan7="inet xx.xx.10.145 netmask 255.255.255.248 vlan 51 vlandev
em1"
ifconfig_vlan8="inet xx.xx.10.161 netmask 255.255.255.224 vlan 52 vlandev
em1"
ifconfig_vlan9="inet xx.xx.10.1 netmask 255.255.255.192 vlan 4000 vlandev
em1"
ifconfig_vlan10="inet xx.xx.14.1 netmask 255.255.255.248 vlan 2001 vlandev
em2"
