Hi Nintin,
Sorry,I did not understand what IOU is. However, what you have tested is
similar to what I am doing.
Except that the area between R4 and R5 for me will not be a backone area.
I see the summary in R2's rip database. But it is not send via RIP to R1.
R2#sh ip rip database
161.1.0.0/16 auto-summary
161.1.0.0/16 redistributed
[5] via 150.1.3.3,
Could not find the solution to this.
Regards
shamin
