Hey John :) i think I got a hold of the scenario here, see if its wat
you are trying to explain:
From what I understand here, you seem to have a loop in the OSPF
domain where the rip routes are redistributed in OSPF but they go into
the OSPF domain and have the potential of cycling and coming back to
this router that is actually redistributing these routes.
When they come back to this router (if they do), they have the
potential of displacing the RIP routes and thereby disrupting this
routers belief of where the routes actually originated from because of
the fact that OSPF routes (AD 110) will displace RIP routes (AD 120).
Now the safest practice here is to make RIP routes have an AD of 109
so that no matter what, this router will always prefer the RIP
prefixes and will always redistribute them into OSPF.
