OSPF Flapping

[Délsio Cabá]

Hi all,

We have 2 bird 2.0.7 instances rpm package running on vmware with MTU 9000

The only issue I cannot find is why they sessions are flapping:

Below the relevant confi:

       ipv4 {
              import none;

      };

        area 0 {
                networks {10.200.2.0/25;};
                stub no;
                interface "*" {

                        hello 10;
                        dead 40;
                        #dead count 100;
                        retransmit 5;
