Sure, it sends query to non-stub neighbors only.
When receiving query, there is message like, "route not in routing table".
Probably it replies with infinite metric.

Subject: Re: EIGRP query: test results
Are you sure about this one:" - A router that used to have the route in it's topology table allways sends
query to all eigrp neighbors unconditionally."?
even if the neighbor configured as stub?
then a question:" - A router which never had that route in its's topology table does not create
any query altough it gets queries on several interfaces."
What does the router do when it gets queries?

Hello Group!
At the end I have made my experiments on EIGRP querying, I share the results
with you.
The results:
- Nor inbound/outbound distribute-list nor summary-address creates border for
query on on interface.
- A router that used to have the route in it's topology table allways sends
query to all eigrp neighbors unconditionally.
- A router which never had that route in its's topology table does not create
any query altough it gets queries on several interfaces.
This way distribute-list, address summarization implicitely makes query
border: if a router does not get a route form uplink neighbors, it does not
create query for them towards the downlink (and uplink) neigbors.
Quite suprising for me, perhaps it is new for some of you.
