ospf: how bird select best route

[Piotr]

Hello,

I advertise default gateway 0/0 from 2 juniper routers into servers with 
bird. On one router (.14) advertise with  metric 30 on second router 
(.9) with metric 70. I see  LSA from both routers but bird always select 
metric 70 as better.. Beside metrics rest configuration are identical..

bird> show  route 0.0.0.0/0
0.0.0.0/0          via 1.1.1.9 on bond0 [MyOSPF 00:11:12] * E2 
(150/10/70) [1.1.1.9]


when i turn off router with higher metric:
bird> show  route 0.0.0.0/0
0.0.0.0/0          via 1.1.1.14 on bond0 [MyOSPF 00:39:45] * E2 
(150/10/30) [1.1.1.14]


and when i turn on again router, bird choose metric 70 as better:

bird> show  route 0.0.0.0/0
0.0.0.0/0          via 1.1.1.9 on bond0 [MyOSPF 00:40:55] * E2 
(150/10/70) [1.1.1.9]



bird> show ospf neighbors

                         authentication none;
                         hello 10;
                         poll 30;
                         type nonbroadcast;
                         neighbors { 1.1.1.9 eligible;
                                     1.1.1.14 eligible;
};
         };
};

};
