Typical VLSM & FLSM issue.
in R5 IGRP router can only redistribute 28 bit route in 137.20.X.X. It will
drop all other routes in the same classful boundary. default route or
summarization is the solution. (use ip default network)
Ip summa is summarize ASBR external route, doesn't influence IGRP at all.

Subject: Redistributing OSPF to IGRP
Hi,
My problem is R4 cannot see R1 routes. Putting "summary-address 137.20.0.0
255.255.0.0" in R5 and redistributing it does not help.
Any idea what is the problem ? Thank-you.
