Ron,
Thanks for your response.
I am assuming a real-lab environment where the rule clearly states that no
static routes of any form can be configured. Using ip default-network will
definitely create static route entry in the routing table and I would not
want to use that except the proctor give's a nod to it.
Area range would only create a summary that would appear on other ospf
routers (sent in the LSU) but would not appear on the ASBR's routing
table(needed for redistribution). Eventually I got summary-address doing it
but the lab sample was testing redistribution between different major networks.
I summarized on R2 using summary-address 172.17.0.0 and it did work.
Thanks Ron.
