router ospf 1
redistribute eigrp 100 subnets
area 0 range 192.168.4.0 255. 255.252.0

Selected Answer: B
Remember that ABRs benefit from the command "area <area-id> range <summary> This command means that from this Area, advertise this range. But Chicago Router is an ASBR, which requires the command "summary-address <summary-prefix>" to summarize routes into the OSPF domain.
