Ok - on Router C (the redistribution router - I changed the network statement from network 192.168.1.18 0.0.0.0 area 0 to network 192.168.1.0 0.0.0.255 area 0 and everything works straight away :)
However, the more puzzling thing is that without any Ip route and Summary-address from Router C (to summarize the OPSF routes before redistributing them into IGRP), how come Router D can still see the routes from OSPF? I thought that it shouldn't be able to see any OSPF routes as they are from /28 subnets..... - apart from the Router A since it is /24. Help!!!
