Hi,I am sorry I am answering bit late.
I think U can use summary address in area 0.
This command causes to generate a route for supernet with null0 as next
hop.So U can very well redistribute this into IGRP.I think in U'r case U
have to generate summary address for/24 (mask of IGRP).
I know the documentation says in otherway.But still it works U can try it.
All the best.
Murali

you can use the area-range command on area0. do it on all the routers that
have an interface running in area 0. summarize them to a /24 or whatever
subnet your IGRP network is.
let us know how it works out.
