...and turning ND into a routing protocol?
From Section 1 of RFC 4191:
We use Router Advertisement messages, instead of some other
protocol like RIP [RFC2080], because Router Advertisements are an
existing standard, stable protocol for router-to-host
communication. Piggybacking this information on existing message
traffic from routers to hosts reduces network overhead. Neighbor
Discovery shares with Multicast Listener Discovery the property
that they both define host-to-router interactions, while shielding
the host from having to participate in more general router-to-
router interactions. In addition, RIP is unsuitable because it does
not carry route lifetimes so it requires frequent message traffic
with greater processing overheads.
