The minute you start radvd, your printer will auto-configure and assign itself an address on fc00:1234:5678:9000. Grab the LL address from the label, ignoring the fe80:: part and append it to the prefix.
You mean its address will be:
fc00:1234:5678:9000:21E:BFF:FE08:4CCB
I can try. [...] No, I can not. I need nfs service and it errors very badly. Just posted about it.
The culprit was precisely that NFS saw the IPv6 addresses of host Telcontar, used it, and Telcontar nfs service went berseck. So I had to remove the IPv6 entries from both name services. Now I installed radv on Isengard.. I saw this in zypper output: Additional rpm output: Updating /etc/sysconfig/radvd ... created /etc/radvd.conf with ULA prefix fd91:e64d:a69a:0001::/64 What is that prefix? I see this in /etc/radvd.conf: interface eth0 { AdvSendAdvert on; # life time zero means we don't actually advertise a # router but only our ULA address. Remove if you want this # host to be advertised as router. AdvDefaultLifetime 0; # ULA address according to RFC 4193. # It was randomly created at installation of the package for # use in your local network. prefix fd91:e64d:a69a:0001::/64 { }; }; I comment it all out and put what you wrote instead. fails to start: Isengard:~ # systemctl status radvd ● radvd.service - IPv6 Router Advertisement Daemon Loaded: loaded (/usr/lib/systemd/system/radvd.service; disabled; vendor preset: disabled) Active: inactive (dead) Isengard:~ # systemctl start radvd Isengard:~ # systemctl status radvd ● radvd.service - IPv6 Router Advertisement Daemon Loaded: loaded (/usr/lib/systemd/system/radvd.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2019-08-12 12:46:55 CEST; 2s ago Process: 1897 ExecStart=/usr/sbin/radvd --nodaemon $RADVD_OPTIONS (code=exited, status=1/FAILURE) Main PID: 1897 (code=exited, status=1/FAILURE) CPU: 5ms Aug 12 12:46:55 Isengard systemd[1]: Started IPv6 Router Advertisement Daemon.

You can now access it from your browser:

Or you add it to /etc/hosts and use 'bilbo6':
