The last. If you don't care about new features, stay at 1.x, current is 1.6.4, otherwise upgrade to 2.x where you have to update also your configs quite a lot. Maria

Remove the old one, install the new one, shutdown the old one, run the new one. BIRD is simple. No docker images, no upgrade procedures.

Hi____
__ __
Your setup looks OK. You could use tcpdump on ens160 to see if there are BGP connection attempts in both directions. Also, is there anything interesting in BIRD logs?____
__ __
You should also upgrade BIRD, version 1.4.5 is too old.____
