To all: Thanks for answering my question. I got it to work by changing
my subnets in the IGRP domain ;)

Passive interface prevents updates from being sent out that
interface, but it doesn't remove the interface from the routing
protocol.

Hi Everyone, 1st Question: I have two routers R2 and
R3 R2----------R3 R2 has 3 interfaces:Lo0: 129.45.80.72 /30E0 :
129.45.80.144 /29S0 : 129.45.80.4 /30 router igrp 100net
129.45.0.0passive-interface lo 0 R3 has 3 interfaces:S0 :
129.45.80.4 /30E0 : 129.45.80.48 /30S1 : 129.45.80.128 /29 router
igrp 100net 129.45.0.0passive-interface e0passive-interface s1 On
R3, when I "sh ip route", I see R2's loopback in my table. Why? I
thought by "passive-int lo 0", I wouldn't see it? 2nd Question: If
I run OSPF on R3's S1 interface, will I be able to redistribute
that into IGRP since it is a /29 ? Please explain, it's been a long
day and I'm not thinking straight.
No. because of the Classless/classfull issues officially this
won't work. What you do is have a default route in IGRP to get you
to the OSPF doamin.
I have included a lab I created to help study this.
