>From what I've been told, none of these are acceptable... No static
routes. No adding networks to your config. And no OSPF summarization...
In the lab the only acceptable solution (again, from what I've been told) is
this... IGRP will automatically summarize any networks into "system"
updates that are not part of the classful network of the interface the
update is being sent on... The "ip default-network" command is placed on
the router which is doing redistribution which then announces this network
as an external route... Boom, default route on your IGRP network. But, this
only works if you have a second classful network in OSPF that will get
summarized by IGRP.... So the third one on the list below is half way right
=)
