Another day, another IPv6 question. I'm on a Hetzner cloud VM. I have a static IPv6 /64 subnet / prefix¹. The system uses systemd-networkd for network management.
My eth0 does not seem to receive any RA at all but I'd like to delegate the prefix downstream to a bridge interface br0 on the same host. I have an IPv6Prefix section on eth0 with the Prefix=…, Assign=yes and Token=static:::1. It works, eth0 gets the ::1 address for this prefix.
Is there a way for br0 to get this prefix too without eth0 joining the bridge? And to announce the prefix to any interfaces joining the bridge (e.g. LX system containers)?
¹ Is this the same? I have the impression these terms are used interchangeably with IPv6.
