Well, if PPP can't handle ip multicast I suggest that we request
the OS group to support ip multicast on our PPP interface.
>From if_ppp.c:
pppattach()
{
register struct ppp_softc *sc;
register int i = 0;
linesw[PPPDISC] = pppdisc;
for (sc = ppp_softc; i < NPPP; sc++) {
sc->sc_if.if_name = "ppp";
sc->sc_if.if_unit = i++;
sc->sc_if.if_mtu = PPP_MTU;
sc->sc_if.if_flags = IFF_POINTOPOINT | IFF_MULTICAST;
^^^^^^^^^
Now if the ip multicast does not work with PPP then I suggest either debugging
the problem or post the problem on the -hackers list.
Regards,
Amancio
