Examine the exhibit carefully.
 
EIGRP is configured on all routers in the network. What conclusion can be derived from the show ip eigrp topology output provided?

A. Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out inquiring for a second successor to network 10.6.1.0/24.

B. Router R1 can send traffic destined for network 10.6.1.0/24 out of interface FastEthernet0/0.

C. Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out before it declares the neighbor unreachable.










 

Suggested Answer: D. Router R1 is waiting for a reply from the neighbor 10.1.2.1 in response to the query sent out about network 10.6.1.0/24.

The show ip eigrp topology command lists all routes that EIGRP is aware of and shows whether EIGRP is actively processing information on that route. Under most normal conditions, the routes should all be in a passive state and no EIGRP process are running for that route. If the routes are active, this could indicate the dreaded stuck in active, or SIA, state.
The fields to note in this output are as follows:
P-- Passive; no EIGRP computation is being performed. This is the ideal state. A-- Active; EIGRP computations are "actively" being performed for this destination.
Routes constantly appearing in an active state indicate a neighbor or query problem.
Both are symptoms of the SIA problem.
U-- Update; an update packet was sent to this destination. Q-- Query; a query packet was sent to this destination. R-- Reply; a reply packet was sent to this destination. Route information-- IP address of the route or network, its subnet mask, and the successor, or next hop to that network, or the feasible successor.
