I am using systemd-networkd for network configuration and the problem I am seeing is that ICMPv6 RA (Route advertisements) are not being sent on the physical (untagged) LAN interface (eno1), while it does work on the VLAN interface (guest).
How can I make RA also work on the untagged LAN interface (eno1)?
$ cat /var/log/syslog |grep RADV
