You have it close (and probably close enough.)  Summarization stops Queries one hop beyond the summary point, by denying the specific knowledge to the peer receiving the summary.  As I stated before, if a router has never heard of a prefix, it immedi...

First, AS 9 will never query AS 5 under any circumstances.  A better way to think about it is that EIGRP will send a Query for a prefix that goes away (or becomes not feasible) if it doesn't have a feasible path and it has any peers to ask. The excep...

As the one who wrote that statement in Optimal Routing Design, it's rewarding to see the book used to answer a question for a real problem. BTW, to be more accurate, the original Query is indeed stopped, but when the route is removed from the rib on ...

You're not using the leak-map in the way it was intended. That feature only works for a particular topology, allowing a subset of prefixes learned from one peer to be leaked to another peer. It will not do what you're trying to do here. As already me...
