Ben,
1st Question
Passive interface just prevents the router from sending advertisements
out a particular interface. This is from the Command Reference
Manual.
Usage Guidelines
This command first appeared in Cisco IOS Release 10.0.
If you disable the sending of routing updates on an interface, the
particular subnet will continue to be advertised to other interfaces,
and updates from other routers on that interface continue to be
received and processed.
2nd Question
Look up this subject header in the Archives. There was a long
discussion about this:
subject: VLSM ---> FLSM or OSPF --> IGRP

Subject: IGRP Issues
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
