Need to see the remainder of your configs. I don't think you are using the
correct area range summary but without knowing your addressing scheme, I
cannot say for sure.

Subject: VLSM, OSPF, and redistribution into IGRP
> I'm working through a scenario in the new Sybex CCIE study guide and I
can't
> get it to work, even using their suggested workaround. Here's the
scenario:
>
> RouterA <--OSPF--> RouterB <--IGRP--> RouterC
>
> RouterA has two different /27 links, one of which is connected to RouterB.
> The connecting link is 10.1.2.0/27 and its other link is 10.1.1.32/27.
>
> The link between RouterB and RouterC is a /24, 10.1.3.0. The purpose of
the
> scenario is to demonstrate that the /27 networks will not be redistributed
> in IGRP because the masks are different on each side of RouterB. To
remedy
> this problem, the book suggests summarizing the /27 networks as /24 which
> would allow them to be redistributed into a classful protocol. Following
> the instructions, on RouterB I added:
>
> router ospf 1
> area 0 range 10.1.1.0 255.255.255.0
>
> Supposedly, this would work but it does not. Closer to their example, I
> even tried "area 0 range 10.1.1.32 255.255.255.0". Am I doing it
> incorrectly or is their suggestion wrong? I worked around this problem by
> creating a summarized static route on RouterB and then redistributing
> static, but I wanted to make it work like in their example.
>
> So, redistribution gurus, what's the story? I quickly looked through
> Doyle's book and I haven't seen this specific example yet.
>
> Any ideas?
