Hello!

Yes, you shall run "birdc conf" yourself when your conffile is ready. What if BIRD started the autoreconfig right when you're writing the file? You could easily get strange behavior like accidentally removing a bunch of protocols by loading a partial config file. You'd have to assure atomic exchange of the file – and this way, you may just run the reconfigure command explicitly anyway.

There are some internal drafts on how to dynamically add routes without having to reload possibly large config files, yet we haven't decided on any approach yet, let aside actually implementing it.

Good evening, I'm doing some tests with BIRD for a while now and I would like some help with a problem I'm facing. I have the following BIRD configuration:

router id 10.0.0.128;

ipv4 table master4;
ipv6 table master6;
flow4 table flowtab4;
flow6 table flowtab6;

filter subnet_group1{
                if(bgp_community.len = 0) then {
                        bgp_community.add((555,555));
                        accept;
                }
                else{ accept; }

};

protocol bgp uplink1{
        local as 129;
        neighbor 10.0.1.128 as 128;
        multihop 1;
        ipv4{
                import filter { accept; };
                export filter subnet_group1;
        };
        ipv6{
                import filter { accept; };
                export filter subnet_group1;
        };
};

protocol static blackhole_ipv4_routes{
        route 10.0.90.100/32 blackhole;
        route 10.0.90.99/32 blackhole;
        ipv4;
};

I created a script that after some time it inserts some new routes into the  blackhole_ipv4_routes protocol defined above, let's say all of 10.0.0.0/24 for example. Is there an option that I could use in the config file to detect this change and update bird accordingly with the new table additions, or do I need to always call 'birdc -configure' after the script ends?
