I'm not sure about that because I have a client network running RIPv2
and my core switches won't generate a default route without either a
route already in the routing table or a static default route.

you can generate default with rip w/wo a default in
rt.

i think from the requirment below...you do
summarization in ospf. then redistribute that null0
route in rip by using route-map to match only that
route.
