the passive interface command just means that it will not send out any
advertisements out that specific interface. If you want an interface
to not show ip in the routing table you could do a distribute list out
from R2
You can try to redist it, but because the network you wish to redist
has a smaller subnet mask than the igrp domain, the igrp process will
not see it as a vald route. Whe using IGRP you can use a default
network command on R3, and advertise it with igrp. There are a
couple of gotchas here though. First you must point to a network
other than the classful network you are running. For example your
default network should be something other than 129.45.0.0. Also the
router that you configure it on must be able to reach the network you
are setting as a default. The network you specify must be on a
classful boundry. ie if R3 sees an entry in its routing table
10.2.1.0/24, you could use the ip defaul network 10.0.0.0 command.
The last thing you must do is to advertise the 10.0.0.0 net from R3's
igrp process with a netwokr 10.0.0.0 command. pages 755 through 758
in Routing TCP/IP Vol 1 by Jeff Doyle has an example.
Hope this helps......

Hi Everyone,
1st Question:
I have two routers R2 and R3
R2----------R3
R2 has 3 interfaces:
Lo0: 129.45.80.72 /30
E0 : 129.45.80.144 /29
S0 : 129.45.80.4 /30
router igrp 100
net 129.45.0.0
passive-interface lo 0
R3 has 3 interfaces:
S0 : 129.45.80.4 /30
E0 : 129.45.80.48 /30
S1 : 129.45.80.128 /29
router igrp 100
net 129.45.0.0
passive-interface e0
passive-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.
Thanks,
Ben
