We do use mpd5 for years as PPPoE/L2TP termination (LNS). The IPv6CP is completely sufficient for IPv6 over PPP. > Will rtadvd automatically listen on the mpd5 ng* interface if the said > interface has a public IPv6 address and a user connects (w/ default > config)? Or will I need to trigger rtadvd manually? You can mount a rtavd on the ng* interfaces, but for other routing issues I already deployed Quagga (long time ago), which is able to provide RA to ng* interfaces, too.
