And again. So this is my Christmas present of stupidity to everyone out there - I hope you are not running into the same issue ever in your life.
If you do, you might be as stupid as me and have a misplaced calico CNI installed on the same node that happens to have a BGP configuration without peers and that happens to also run bird (albeit version 1.6). If you read previous mails and you felt like "this sounds awfully as if there are two routing daemons competing for the route table", well then you were right, that was exactly the problem.
