Hi Bradford,
Can you try the config below on R2, i have a similar lab
with ospf/igrp and it works.
Summary you can use to summarize the rip domain into ospf
but not ospf domain back into rip.
Let me know the result please.
regards
Louis

The question is I can red ospf/27 network into rip/24 by below:
1. OSPF
=======
At R1, create a new ospf process(ospf_2),redsitribute the orginal
ospf(subnets) into ospf_2, address summary at ospf_2 on those non /24
into
/24. At rip, redistribute ispf_2 into rip.
However, Why 150.20.78.0/24 can't be red into rip as it is /24 network?
