Why are you planning on splitting up your EIGRP AS? It won't improve scaling in any way, so I would address that question first. I've seen, and worked on, networks with over 2000 routers in a single EIGRP AS, running without problems, and larger networks are possible.


If you really must, then make certain you are running later code, at least 12.2, and then make certain you tag your routes in a route map when you redistribute, then filter on those tags at the same redistribution points. Take a look at:
