You have to summarize your routes into a mask IGRP will understand. Summary
address will not work as it summarizes into OSPF areas. Try "area x range
x.x.x.0 x.x.x.255". Then redistribute into IGRP. I would watch out for the
secondary address. Proctors might not like that solution.

Subject: AGAIN! IGRP OSPF redis

Hi All,

Pls consider the following simple topology for redis OSPF into IGRP.

                            s0 s1
R2----------------------R1---------------------
     172.16.1.0/24 172.16.2.0/28

R2 runs IGRP only
R1 runs IGRP on S0 and OSPF on S1, and there is a big OSPF cloud attached
from
S1.
you are trying to redis ospf into igrp, in this case, I am talking how to
redis the 172.16.2.0/28 into R1.

I know in ios 12.1, the normal "redis connect" and "summary" way doesn't
work, but I also hear about that the "second address" works, any one could
show me a light about where to put the secondary address.

Thanks, V
