C,
That's another way to do it ... use ip default-network at R3 and have IGRP
originate for R4 (this would be the best way if there are more IGRP routers
downstream).
But Darryl only has R4 left without a default-route, so the easy way is just
to install a default route on R4 with "ip route 0.0.0 0.0.0.0 X.X.X.X" and
not bother getting it into IGRP.
