RE: OSPF into IGRP using Summarization solution

Hi,

I use the IOS 12.1(5)T10 as the same as used in the
Lab and it works just fine for connected
redistribution.

If redistibution of connected interface does not work,
you can try to summarize it in R6's tunnel interface
as follows:

int tu0
ip summary-address rip 135.4.24.0 255.255.255.0

You will receive a classful route in R5 from rip
process. Then, you redistribute it into IGRP. I just
just tried it and it works fine.
