IP addresses and routing for the network are configured as shown in the exhibit. The network
administrator issues the show ip eigrp neighbors command from Router1 and receives the output
shown below the topology. Which statement is true?

A.
The IP addresses are not configured properly on the Router1 and Router3 interfaces.

B.
The no auto-summary command configured on the routers prevents Router1 and Router2 from
forming a neighbor relationship.

C.
Routing is not completely configured on Router3.

D.
It is normal for Router1 to show one active neighbor at a time to prevent routing loops.

Explanation:
The Router 3 is connected to three different networks: 192.168.3.1/30, 192.168.2.2/30, and
10.0.4.0/24 but only 10.0.4.0 and 192.168.2.0 are being advertised via EIGRP. In Router3, the
“network 192.168.3.0” command should be placed under the EIGRP 10 process.
