Bird does not export routes with different proto

26 Aug 2018

      Hi guys,

i tried to announce routes via ospf first time. Till now i use babel to
get my routes in my table. Now i want to announce the babel routes
trough my ospf as well.

But here i see, even if import and export filters are set on all that
bird ist not collecting this routes from my kernel table.

Is there a reason for it or can i configure this?

My Config:

router1:

    #/etc/bird/bird.conf

    log syslog all;
    router id 163.172.107.146;

    protocol direct {
        interface "lo";
        interface "bb-a-ak-ber";
        interface "bb-b-ak-ber";
        interface "bb-a-ix-dus";
        interface "bb-b-ix-dus";
        interface "bb-a-fra";
        interface "bb-b-fra";
        interface "ens18";
    };

    protocol kernel {
            device routes;
            import all;
            export all;
            kernel table 200;
    };

    protocol device {
            scan time 10;
    };

    protocol ospf IGP {
        import all;
        export all;
        area 0 {
            interface "lo" {
                stub yes;
            };

            interface "ens18";
        };

    192.168.48.0/24 dev ens18 proto bird scope link

As you can see, there are not all the routes from router1.

Thanks in advance!
