I've tried posting this about 10 times over the last month and it seems that
I don't have any problems when I reply to someone's post, but if I create a
new thread it never makes it to the list.
Has anyone done any testing with eigrp stub areas? We are trying to look
for ways to reduce the diameter of our network so that there aren't so many
queries when a route goes active. We are very interested in using the eigrp
stub area command, but I've only heard from people using it in a lab
environment and I haven't been able to find much documentation on CCO. Any
advice or experiences would be greatly appreciated.

Ed, if you have a moment, can you answer a question. For the automatic
redistribution to take place, don't the two routing protocols, with the same
process i.d. have to be on the same router? Or will they do this when
adjacent? I did a quick lab on this a while back, but during the remodel my
place is a mess and I can't find most my logs ( definitely one of the habits
of the successful CCIE candidate is never remodel your workspace ever :-> )
Also, dare I suggest that with (E)IGRP, the routing process has local
significance, in that it is local only to routers defined within the same
AS/process? :->

When EIGRP and IGRP share the same AS, redistribution in automatic.
However, keep in mind that EIGRP will handle VLSM, and IGRP is a classful.
As I see it, EIGRP on the left advertises routes to IGRP in the middle, and
then it would advertise classful routes to EIGRP on the right. I believe
routing information would most likely be lost if the subnets are
discontiguous.
In the second scenario, with different AS, the above would be true but you
would have to manually redistribute between protocols.
