Actually, you can clear EIGRP neighboring in conjuntion with debug to
see all routes advertized to neighbors.
debug ip routing, and
debug ip eigrp
clear ip eigrp neighbor

Subject: RE: Route advertise to eigrp neighbors
Hi,
You can use debug ip routing, and debug ip eigrp (event) to see how
things happening.
Remember that EIGRP is a hybrid protocol, so you will not see a periodic
updates like RIP, but only update as change occurs. If there's a change
to a route, you will see update for that route ONLY, and you do not see
"all routes" that a router sends to a neighbor. Not like RIP!
See below for how router report change for the loopback 150.1.1.0/25 to
its neighbor.
