Since PPP does not support multicast, this will involve a smart NDP that
takes into consideration the type of interface as well i.e. we cannot send
a router solicitation to the all-routers address/send a router
advertisement to all-nodes and so on.

Is this what most implementations do? I would like to know if most
implementations use NDP over PPP in some way.

Thanks,
Lilian
