Tom,

It stops that interface from sending packets of that routing protocol. With
RIP, that means no routes are sent out, but routes are still learned.
However, wtih EIGRP or OSPF no neighbor relationships will be formed, and no
routes learned. OSPF has the command "ip ospf database-filter all out" to
stop LSAs from being sent out that interface, so it allows neighbor
relationships to be formed and routes to be learned from a neighbor, but no
routes to be sent out that interface.
