how to use fib and bird

Hi,

I'm trying to advertise and get routing info via BGP andbird in a distinct fib but it seems that bird is always trying to connect to peers on the Fib 0. I tried the following configuration:

```
    protocol bgp transit_ipv4_1 {
        local A.B.C.1 as XXXX;
        neighbor A.B.C.0 as XXXX;
        default bgp_med 0;
        default bgp_local_pref 50;
        password "somepass";
        ipv4 {
            import keep filtered;
            import filter ebgp_import;
            export filter ebgp_export;
              igp table enki_tabv4;
                next hop self;
        };
    };
```

where the enki_tabv4 should be populated via the kernel protocol:


```
    protocol kernel enkiv4 {
            learn;
            kernel table 1;
            ipv4 {
                    table enki_tabv4;
                    import all;
                    export filter export_kernel;
            };
    }

```

I say "should be" because apparentlyit isn't and I get such error:

```
2023-06-06 02:05:58.571 <TRACE> enkiv4: A.B.C.D/24: ignored
    2023-06-06 02:05:58.571 <TRACE> enkiv4: A.B.C.D/32: [alien] 

...


2023-06-06 02:05:58.571 <TRACE> enkiv4.ipv4 > added [best] A.B.C.D/32 0L 4G unicast
2023-06-06 02:05:58.571 <TRACE> enkiv4.ipv4 < rejected by protocol A.B.C.D/32 0L 4G unicast
```

How can I tell the bgp protocol to look at the routing info in the fib 1 to connect?
