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
IP-EIGRP Topology Table for AS(50)/ID(192.168.6.1)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status
P 2.2.2.2/32, 1 successors, FD is 128256
via Connected, Loopback2

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.The only easy day was yesterday! -

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 ACKWhat's another word for Thesaurus? -

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.
