Passive-interface will stop the sending of information but not the
receiving. With protocols that form adjacencies using hellos, such as
EIGRP and OSPF, the passive-interface will stop hellos from being sent
and the adjacencies forming resulting in no routing updates in or out.
With protocols such as RIP, however, where adjacencies are not formed, a
passive-interface is still able to receive routing information which
will be entered into the routing table, and not discarded.

The classful network stated under EIGRP will be propagated in
the EIGRP
updades.
If the interface is in a network or subnetnet that is defined in
the EIGRP
it will be elegible to send or receive EIGRP update
information. The
"passive-interface" command will discard the reciving and stop the
sending
of EIGRP information through that interface. This will happen in
EIGRP,
IGRP, RIP, RIPv2, OSPF, IS-IS and BGP work in a different manner.

Does this "passive interface command" makes EIGRP not to run on that I/F
or
not to advertise on that I/F? I mean with this command is the I/F will
be
still in EIGRP I/F list or not?

Under the router eigrp configuration - use the command:
passive-interface serial 1
This will make sure it does not run on serial 1.
In terms of redistribution - make sure that you have some form of metric
specified. Otherwise more information is needed to work out why it is
not
working for you.

In a lab setup, I have both EIGRP and OSPF running. Here is the basic
setup
Int S0
ip add 192.63.65.6 255.255.255.252
Int S1
ip add 192.63.65.9 255.255.255.252
Router EIGRP 100
network 192.63.65.0
(every time I enter 192.63.65.4, it changes in the show run)
Router OSPF 100
network 192.63.65.8 0.0.0.3 area 0
When I try and redistribute the routes, the OSPF routes make it to the
EIGRP
side no problem, but the EIGRP routes are not seen on the OSPF side. If
I
look at the eigrp interfaces, or neighbors, they both show S1.
Any clue?
Thanks in advance, Howard
