For RIP, although you configure neighbor command, RIP updates still sent to multicast address 224.0.0.9. You need to define an access-list to prevent this

This is true for RIP but I am not sure about EIGRP. I know for a fact that
in EIGRP the passive-interface will prevent the formation of neighbors.

I believe the neighbor command is used to send routing annoucements as
unicast packets instead of multicast or broadcast cast packets. For
instance, there may be 5 routers on a segment but only two of them are
using the same routing protocol. Instead of needlessly sending updates to
the other routers, you could use a passive-interface to block the
broadcasts/multicasts on the interface and instead send a directed unicast.
Someone please correct me if I am wrong.
