radvd is IPv6 Router Advertisement. It’s turned on by default when you install ipv6 package. To turn it off (so the router doesn’t advertise IPv6)

/ipv6 nd print
Flags: X - disabled, I - invalid
 0 X interface=all ra-interval=3m20s-10m ra-delay=3s mtu=unspecified reachable-time=unspecifie>
     retransmit-interval=unspecified ra-lifetime=30m hop-limit=unspecified
     advertise-mac-address=yes advertise-dns=no managed-address-configuration=no
     other-configuration=no

/ipv6 nd set 0 disabled=yes

Thanks alot!
