First, please do not put everything in the same AS.
This is a very bad thing, and I really wish Cisco
would kill the feature. (I think it was placed in
there for marketing)
There are two standard ways to do this. The first is
border - you simply redistribute and filter with
distribute lists. The redistribution point can be
moved as you convert, or more added (although you
should only have two routers invloved if possible).
The other is overlay. Both IGRP and EIGRP run on all
routers in the network, but EIGRP's AD is weighted
higher. Then you pull IGRP off. Any router that is not
running IGRP will advertise the routes via EIGRP, and
the only real trick is memory and making sure that you
work from the outside in on the IGRP removal.
