If you don't use a classful address for the IP default-network then the
router will install a static default route that shows up in your sho run.
BTW what would you do if you couldn't use the IP Default-detwork command?
Is that what everyone has been talking about with this "reverse summary
address" thread? Thanks in advance...

I think Caslow means that the router that "knows everything" (has both the
IGRP and OSPF routes, assuming OSPF is the VLSM protocol) should "announce"
a default network to the rest of the IGRP domain.
You do this with the global: "ip default-network" command. The
restrictions are (I believe) that the network designated with this command
must be both classful, and one that is already being advertised into the
IGRP domain (so when other IGRP domain speakers hear the "default network
announcement", they actually know about the network being announced).
Hope this helps.
Thank you,

Subject: Redistribution - Caslow book
In Bruce Caslow book chapter 12 (redistribution of IP routes) page
425 (page 421 in older edition) he lists two solutions for redistributing
between VLSM and FLSM
environments.
How do you configure solution two?: Announce an IP default-network
on the redistributing router into the IGRP domain. Enable IP classless on
all IGRP routers with the global configuration command "ip classless."
He does not provide an example on how to implement solution two.
Thanks,
Vadim
