Thansk Yemi,
Well there we go then. Another one for the tool box.
Just to add to the redistribution situation, apparently the default network
of 0.0.0.0 used by RIP cannot be redistributed by EIGRP.
So bother trying to add or block that with this command :)

That's where default-information differs from distribute-list,
distribute-list as we know, traditionally prevents certain routes from
being advertised to EIGRP neighbors or prevent certain routes from being
added to the RIB table.
Defualt-information on the other hand deals with exterior and defualt
route "across redistribution points/routing domains".
Many Thanks
Yemi Salau

That's my understanding of it. I wonder if it can suppress default
information coming from a peer in it's own EIGRP AS?
