The passive-interface command keeps EIGRP from sending updates out of an
interface and it keeps it from forming a neighbor adjacency out that
interface. But it is not intended to keep the protocol from advertising a
connected network that is otherwise covered by a network statement. Try a
distribute-list out command to filter these updates.
