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?
