Passive Interface for EIGRP has a bit of an unusual behavior.
For most of the interior routing protocols passive interface indicates
not to send advertisements but to continue to listen for advertisements.
With EIGRP use of passive interface will prevent sending of Hello
messages and therefore will prevent formation of neighbor relationships
with any other router on that subnet.
However use of passive interface has no effect on advertising that subnet
on active interfaces. The point of the original post was that he did not
want the subnet advertised. Passive interface will not achieve that.
I do not see a solution other than use of mask on the network statement
(a feature in some releases of 12.0) or a distribute list.
