Vladimir, I love the direction you are going with cilium and bird. We actually had cilium on our list for potential CNIs, but hold yourself: had to drop it, because cilium does NOT work on IPv6 only hosts! I.e. if the k8s workers are IPv6 only, cilium crashes [0]. In case you make any progress in that direction, I'd love to hear from you. BR from Switzerland, Nico [0] https://redmine.ungleich.ch/projects/open-infrastructure/wiki/The_ungleich_k...

Thanks, that was it!
I must have missed the note in the docs on that, because with ipv4 I just had the same subnet, but with ipv6 I don't have a public address assigned on the bird side. `multihop 1` Fixed the negotiation issue. I got a few more, but those seem to be related to either gobgp sending malformed updates (Invalid NEXT_HOP attribute - mismatched address family (2a01:xx:yy:zz:4746:92e9:327c:d930 for ipv4)), or the bird configuration not being able to parse a `-` in the interface name. Both unrelated to this particular issue at hand.
