I am using FreeBSD 14 with FIBs.

With bird2.14 I get routes via BGP and anything is fine.

With bird2.15.1 I get routes, but the daemon doesn’t put them into the kernel routing table. Same configuration work with older version.

Does something change which has an effect on it?

template bgp general_bgp {

    debug { states, routes, interfaces };

    strict bind on;

    enable route refresh on;

    graceful restart time 300;

    hold time 15;

    keepalive time 5;

    med metric on;

    password "*************";

}

ipv4 table table_SLICE1

protocol direct direct_SLICE1 {

  interface "vtnet2";

  ipv4 {

    table table_SLICE1;

  };

}

protocol kernel kernel_SLICE1 {

  kernel table 1;

  scan time 10;

  ipv4 {

    table table_SLICE1;

    import all;

    export all;

  };

}

### br1

protocol bgp br1_SLICE1 from general_bgp {

  description "[SLICE1][br1] - BGP Transit Services";

  local 100.64.1.185 as 64521;

  neighbor 100.64.1.7 as 64521;

  ipv4 {

    table table_SLICE1;

    import keep filtered;

    import all;

    export none;

  };

}

### br2

protocol bgp br2_SLICE1 from general_bgp {

  description "[SLICE1][br2] - BGP Transit Services";

  local 100.64.1.185 as 64521;

  neighbor 100.64.1.8 as 64521;

  ipv4 {

    table table_SLICE1;

    import keep filtered;

    import all;

    export none;

  };

}
