Clarification to my previous message from Rick Burts.
Access to great minds is the best of this group study. I hope that even
after you all earn your CCIE that you will contribute(for a little while at
least) to the group.

I wish you had phrased your answer a bit differently. It is not so
much that IGRP does not understand classesss addressing. It is that
IGRP will not understand mixed mask lengths. It certainly understands
more than 8/16/24, you can certainly redistribute a /28 (or whatever
prefix length) so long as IGRP has been configured with that as the
subnet mask. But you cannot redistribute both a /28 and a /30.
