stupid question about OSPF cost and route preference

Hello. I have a bunch of birder routers, and the troublesome router is connected to some of them via LAN and to some of them via WAN tunnels. For some reason it always chooses a WAN route, regardless of it's metric: ===Cut=== bird> show route for 10.50.3.0/24 10.50.3.0/24       via 172.16.0.45 on gif1 [ospfv4 18:25:39] * E2 (150/10222/10000) [192.168.57.254] [root@gw /usr/local/etc]# ifconfig gif1 down [root@gw /usr/local/etc]# birdc BIRD 1.6.6 ready. bird> show route for 10.50.3.0/24 10.50.3.0/24       via 192.168.57.254 on vlan57 [ospfv4 18:33:37] * E2 (150/11/10000) [192.168.57.254] [root@gw /usr/local/etc]# ifconfig gif1 up [root@gw /usr/local/etc]# birdc BIRD 1.6.6 ready. bird> show route for 10.50.3.0/24 10.50.3.0/24       via 172.16.0.45 on gif1 [ospfv4 18:34:01] * E2 (150/10222/10000) [192.168.57.254] bird> ===Cut=== And I totally don't understand why (OSPF cost is several times higher !). Config is  as follows: === Cut=== filter importospfv4 {     if net ~ [ 10.8.1.0/24 ] then {            reject;     } else {            accept;     } } filter exportospfv4 {     if net ~ [ 192.168.55.254/32, 192.168.57.2/32 ] then {           reject;     } else {           accept;     } } protocol ospf ospfv4 {     export filter exportospfv4;     import filter importospfv4;     area 0.0.0.0 {         interface "vlan55" {              cost 11;         };         interface "vlan57" {              cost 11;         };     };     area 0.0.0.1 {         interface "gif0"{               cost 5111;         };         interface "gif1" {               cost 5111;         };     }; } ===Cut=== Thanks. Eugene.
