Hi Aamer, This is another solution without static routes. The idea is still the same, break 10.0.0.0/24 to smaller /30 networks to fit with the interface of IGRP domain (10.3.255.8/30), using "summary-address" at OSPF.
r2#sh run router ospf 1 summary-address 10.0.0.0 255.255.255.252 summary-address 10.0.1.0 255.255.255.252 redistribute igrp 1 metric 10 subnets network 10.0.0.0 0.0.0.31 area 0 network 10.0.1.0 0.0.0.255 area 1 neighbor 10.0.0.6 priority 1 neighbor 10.0.0.5 priority 1 ! router igrp 1 redistribute ospf 1 route-map o2i passive-interface Serial0.24 passive-interface Serial0.100 network 10.0.0.0 default-metric 10000 100 255 1 1500 ! ip classless no ip http server ! access-list 101 permit ip host 10.0.0.0 host 255.255.255.252 access-list 101 permit ip host 10.0.1.0 host 255.255.255.252 route-map o2i permit 10 match ip address 101 !
