I assume that ospf is not very familiar for you so I give tip what can
save mutch time. You need use same hello and dead timer in all devices
in same L2.
There is our config for our anycast dns server. With that config we use 
/32 mask in anycast ip as extra ip in server main interface. And in some
cases you need also ip_forward to set 1.
This sample conf is not wery strict (you can soot yo your leg if you
have static routes or if that dns server is not dedicated for that
purpose) but anyway it works ;)

log "/var/log/bird.log" all; #this is very verbose so you maybe want
something else
router id 11.22.33.44; # fix this to uniq ip formatted id


protocol kernel {
        persist;                # Don't remove routes on bird shutdown
        scan time 20;           # Scan kernel routing table every 20 seconds
        import none;            # Default is import all but we trus our
default route
        export all;             # Default is export none but we want
announce our interface ip
}

# This pseudo-protocol watches all interface up/down events.
protocol device {
        scan time 10;           # Scan interfaces every 10 seconds
}

protocol static {
}

protocol ospf ownospf {
        debug { states, events };
        tick 2;
        rfc1583compat yes;
        export filter
        {
                accept;
        };

        area 0.0.0.0 {
                interface "eth0" {
                        hello 1;
                        dead 10;
                };
        };

};
