Refer to the exhibit. EIGRP is configured on all routers in the network. On a basis of the
show ip eigrp topology output provided, what conclusion can be derived? Select the best
response.

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

B.
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.

C.
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.

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.

Explanation:
From the output, we notice that there is an active route (A) and the reply status flag (r) was
set. An active EIGRP route is the state when a network change occurs and a feasible
successor is not found by a EIGRP router for a given route (10.6.1.0/24); and the reply
status flag (r) means that R1′s queries were sent out to the neighbors asking forrouting
information to the 10.6.1.0/24 network but hasn’t received a reply yet. Therefore the answer
A – router R1 can send traffic destined for network10.6.1.0/24 is not correct because router
R1 can’t find a path to that network. Answers B andC are not correct because R1 doesn’t
send a hello message but a query asking for routinginformation to the desired network.
