default gateway

[Jaroslav Jirásek]

Hi , I want to create ring network with OSPF. It works for me, but I cannot 
propagate default route to ring.
On router with internet access I have this configuration:

router id x.x.x.x

protocol kernel {
        persist;
        scan time 20;
        import all;
        export all;
}

protocol device {
        scan time 10;
}

protocol static {
        route 0.0.0.0/0 via x.x.x.y;
}

protocol ospf MyOSPF {
        tick 2;
        rfc1583compat yes;
        area 10.32.0.0 {
                stub no;
                networks {
                        a.a.a.a/30;
                        b.b.b.b/30;
                };
                interface "vlan10" {
                        hello 10;
                        retransmit 5;
                        cost 10;
                        transmit delay 1;
                        dead 40;
                        wait 40;
                        type broadcast;
                        authentication none;
                };
                interface "vlan11" {
                        hello 10;
                        retransmit 5;
                        cost 100;
                        transmit delay 1;
                        dead 40;
                        wait 40;
                        type broadcast;
                        authentication none;
                };
        };
}

Other routers in ring are MikroTik routers.
Thank you for any hint.
