does nayone know where about the coded will apear in the readout. for example if the router sends a query to a neighbor where will the Q code show in the readout

R2_2611xm#show ip eigrp topology

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status

P, 1 successors, FD is 128256

    Yes but because "A", "U", or "Q" are typically just transitive state back to "P" you usually don't see anything other than "P" or possibly "s" when working in a lab.

    this is thinking about it way to hard but

    if a router receives a query from a neighbor for a route that it has a successor for that isn't the querying router, then the router will just send a reply without the route changing from passive, right.

    so would the 'R' display in the topology table just until the packet is ACK

    It happens fast. Like DT said, you probably will not EVER see it.

    One way you can see the topology change in a different way is to enable debugging for eigrp, then do a high # ping on one router, and then go back another router and shut down one of the eigrp interface, you'll see a '....' among a sea of '!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!', and the moment that you see the '...', you can check the corresponding debugging message that contains the topology change message.

    This is covered in the BSCI Student Lab and it's really neat.
