Hi Volker, I am missing the mask you use for the various networks. i think you would get it to work with a setup like this: A has Ipv6-Address 2001:1::1 B has Ipv6-Address 2001:2::1 C has Ipv6-Address 2001:3::1 and a /64 mask
I think in your setup al ip addresses are in the same subnet, so routing will not be done. I hope this helps.
