Redistribution techniques

Group,

I have included the forwarding tables and configs for two routers that are
performing mutual redistribution between OSPF and IGRP. I have been
successful solving the problem with summarization and by using
default-network. Does anyone have suggestions for other ways to solve this
problem?
