I think the correct behaviour is that only the ABR should do the area x
range command.( any area)

Subject: about OSPF summarization

Hi all,

in ccie real lab, what's the cisco IOS version?

I have a problem on IOS about OSPF summarization.
my OSPF is redistributed to IGRP(r4) domain.
between ospf and igrp, the network mask is /24.
so i need to summarization mask's/29 to /24.
but i have some ios problem.

on ios 12.1.9 the internal summarization is good.

but on ios 12.1.5
the router is not make the summarization route.
