When you redistribute from OSPF to IGRP the only routes that will
redistribute (within a common major net) are the ones that have the same
mask used by IGRP interfaces.
So, Summary-address helps and so does secondary addressing. HTH

Subject: OSPF and IGRP redistribution question
When you mutually redistribute between OSPF and IGRP,
and do not see all the subnetted OSPF routes in a
router running IGRP only, what do you do to get the
routes in that router (running IGRP). Also, how does
the mask configured on the router running IGRP have
anything to do with the redistribution.
I know two things, that help not loose connectivity:
1) Use the summary address in OSPF to summarize the
routes you want to see in the router running IGRP.
2) Annonce an IP default-network on the redistributing
router pointing to the IGRP domain.
This has never worked for me and am i supposed to see
these routes in the router running IGRP after i use
one of the above command?
How does the lenght of the mask in interfaces
configured for IGRP come into play?
I am very confused.
Does anybody has an better explanation or maybe a
document i can read to better understand this issue.
Regards,
BD
