Hello,

I'm trying to simplify my old bird 1.6 config, the aim is migrating to v2 then v3.

I have a config like :

template bgp private_peering_ipv4 {
    local as my_ans;
    path metric 2;
    ipv4 {
            import all;
            import filter {
                if (net.len > 24 ) then reject;

                bgp_large_community.add((my_asn, 1, 1003));
                accept;
            };
            export filter export_my_routes_ipv4;
            import keep filtered;
    };
}

protocol bgp PEER_v4_peer1 from private_peering_ipv4 {

    router id 195.42.145.x;

    neighbor 195.42.144.104 as 6939;

}

protocol bgp PEER_v4_peer2 from private_peering_ipv4 {

    router id 195.42.145.x;

    neighbor 195.42.144.104 as 6939;

    ipv4 {

            import filter {

                bgp_large_community.add((my_asn, 1, 1009));

                accept;

            };

   };

}

the problem here is that as soon as I define a new import filter for my second peer, the filter from the template is omitted.

Is there a way to add inheritance between the templates, or anything else that wouldn't overwrite the template filters ?

Regards,

Cédric
