why dont you give a secondary IP address to OSPF IGRP redistribution link
(the connection between ASBR and pure IGRP router) with /21 mask. So you
will be able to redistribute /21 route from OSPF to IGRP. On the router
where EIGRP OSPF redistribution occurs you should be putting
summary-address 1.1.0.0 255.255.248.0
Any other ideas ?
