Not sure if you have Bruce Caslow's book but this exact problem is in one of hi
s spot the issues. Chapter 12 number 1.
Here it is....
A router is running RIP and OSPF. Both routing protocols are using 172.16.0.0
address space. The router also has twp 172.16.0.0 subnets connected. RIP redi
stribution did not inject the routes into OSPF. Redistribute connected injecte
d them in. Why?
Answer...
Even though the two directly-connected subnets are defined as RIP subnets, they
are listed as connected subnets on the router. Therefore, redistribute connec
ted must be used to redistribute the routes into OSPF.
HTH.

Subject: Redistribute ospf1-> ospf2->rip
Hi all
Here is the scenario.
Loopbacks
R1(e0)-----------(e0)R2------172.16.1.1/28
172.16.1.17/28
172.16.1.33/28
What I want to do is ultimately to redistribute these three loopback
networks into rip.
R2 is ASBR running ospf and rip. R1 is running only rip.
As the people on this list recommended, I first created ospf 2 and
redistributed ospf 1 into ospf 2. And during this redistribution from ospf2
to ospf1, I summarized three loopback networks to the classful address (
172.16.0.0/16) And I redistributed ospf 2 into rip.
NOT WORKING :-(
Here is my config
R2;

!
interface Loopback1
ip address 172.16.1.1 255.255.255.240

R1's routing table;
R1#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter
area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.1.0/24 is directly connected, Ethernet0
C 192.168.3.0/24 is directly connected, Loopback1
As you can see, those three loopbacks didn't show up in this routing table,
which means it is not working.
Can anyone point out what is wrong?
I will appreciate your reply.
