route ipv6 prefix to a vlan

Is there a way to route correctly an IPv6 /56 prefix to another machine without using DHCPv6? The idea is to route this prefix to another interface and then from then send /64 addresses to pmahines connected to this router using RA. Any hint is welcome :slight_smile:

Regular static route, where gateway is link-local (fe80:…) address of target machine.

thanks!
