How to stop EIGRP from querying another router

I've been reading everything I can on stub routing and for some reason, I can't seem to make this work. I'm trying to complete this lab and i'm stuck on the last objective

EIGRP Intermediate | EIGRP

I've configured R3 as a stub router so R1 won't query it when R1 loses a route to another node on the network. However, when I enable debug eigrp packets query reply on R3 and shut down the Loopback interface on R2 which is an EIGRP advertised route to R1, I still see R1 querying R3 for the lost route.

Any ideas...this is driving me nuts :)

    Maybe stop advertising the 2.0.0.0 network?

    from router configuration mode:

    no network 2.0.0.0

    I'm not sure if that will work though, just a thought.

    Are you sure you're not just seeing R3 send a QUERY to R1 and not the other way around?

    That may very well be...I saw the IP of R1 in the debug output and assumed that R1 was querying R3.

    This is the output of debug eigrp packets query reply on R3 when I shut down Lo1 on R2

    *Mar 1 00:15:10.971: EIGRP: Enqueueing QUERY on FastEthernet0/0 iidbQ un/rely 0/1 serno 15-15
    *Mar 1 00:15:10.975: EIGRP: Enqueueing QUERY on FastEthernet0/0 nbr 192.168.13.1 iidbQ un/rely 0/0 peerQ un/rely 0/0 serno 15-15

    As you can see its sending the query and receiving a reply.

    The "EIGRP: Enqueueing QUERY" is what threw me off....when I first looked at it, I thought it was an inbound query that was being put in a queue and that the EIGRP stub command wasn't doing what I thought it was supposed to...but apparently it was...

    VIPER: "Yeah...you did it right"

    :)

    Now i need to brush up on interpreting my EIGRP debug output.
