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:<br>
<br>
<b>router id 10.0.0.128;</b>
<div><b><br>
</b></div>
<div><b>ipv4 table master4;</b></div>
<div><b>ipv6 table master6;</b></div>
<div><b>flow4 table flowtab4;</b></div>
<div><b>flow6 table flowtab6;</b></div>
<div><b><br>
</b></div>
<div><b>filter subnet_group1{</b></div>
<div><b> if(bgp_community.len = 0) then {</b></div>
<div><b> bgp_community.add((555,555));</b></div>
<div><b> accept;</b></div>
<div><b> }</b></div>
<div><b> else{ accept; }</b></div>
<div><b><br>
</b></div>
<div><b>};</b></div>
<div><b><br>
</b></div>
<div><b>protocol bgp uplink1{</b></div>
<div><b> local as 129;</b></div>
<div><b> neighbor 10.0.1.128 as 128;</b></div>
<div><b> multihop 1;</b></div>
<div><b> ipv4{</b></div>
<div><b> import filter { accept; };</b></div>
<div><b> export filter subnet_group1;</b></div>
<div><b> };</b></div>
<div><b> ipv6{</b></div>
<div><b> import filter { accept; };</b></div>
<div><b> export filter subnet_group1;</b></div>
<div><b> };</b></div>
<div><b>};</b></div>
<div>
<div><b><br>
</b></div>
<div><b>protocol static blackhole_ipv4_routes{</b></div>
</div>
<div><b> route <a href="http://10.0.90.100/32" target="_blank">10.0.90.100/32</a> blackhole;</b></div>
<div><b> route <a href="http://10.0.90.99/32" target="_blank">10.0.90.99/32</a> blackhole;</b></div>
<div><b> ipv4;</b></div>
<b>};</b><br>
<br>
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 <a href="http://10.0.0.0/24" target="_blank">10.0.0.0/24</a> 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?<br>
