Wayne,
Thats a good question. Another way to do it is to deny all OSPF routes from
being redistributed from IGRP to OSPF. This is to prevent redistribution
feedback, another way to do it is to use turn on split horizon.
I'm pondering this question as well, as I see from examples in Doyle that
redistribution between IGPs should be done carefully, so filtering via
route-maps or distribute-list is required. That means you have to use
route-maps and distribute-lists for all routers that are doing
redistribution between two protocols. But Heck!!! I've seen examples that
don't use filtering, and it still works!!
My thoughts are that the filtering is there for precautionary measures, just
in case routes do feed back into the routing protocol it originated from.
There's also the admin distance that has to be taken into account of.
If anyone has any suggestions of the proper way of doing this, please let me
kno
Thanks
Albert

When redistributing IGRP to OSPF, is it acceptable to only redistribute
the
precise IGRP routes via a route map on the lab exam? Or is the
redistribution supposed to be dynamic enough that it would allow more IGRP
routes to be redistributed should (hypothetically, but not really) other
IGRP routes be added later?
Thanks,
Wayne
