jim, dave and the vibe AP are pure L2, but RouterOS ships ip-forward and
IPv6 forward on, and with IPv6 forwarding enabled it also advertises
itself as a default router. After the 7.18 -> 7.23 upgrade clients began
picking up the switches as IPv6 default routers alongside river.
Replace the earlier advertise-dns framing (which only strips RA options,
not the router lifetime) with the actual requirement: ip-forward=no,
IPv6 forward=no, accept-router-advertisements=no, ra-lifetime=0, and a
re-check after every RouterOS upgrade.
