Scenario Refer to the topology. Your company has connected the routers R1. R2. and R3 with serial
links.
R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also
connected to the routers R4 and R5. The EIGRP routing protocol is configured. You are required to
troubleshoot and resolve the EIGRP issues between the various routers. Use the appropriate show
commands to troubleshoot the issues.
Study the following output taken on R1: R1# Ping 10.5.5.55 source 10.1.1.1 Type escape sequence to
abort. Sending 5.100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds:
Packet sent with a source address of 10.1.1.1
Why are the pings failing?
A.
The network statement is missing on R5.
B.
The loopback interface is shut down on R5.
C.
The network statement is missing on R1.
D.
The IP address that is configured on the Lo1 interface on R5 is incorrect.
Explanation:
R5 does not have a route to the 10.1.1.1 network, which is the loopback0 IP address of R1. When
looking at the EIGRP configuration on R1, we see that the 10.1.1.1 network statement is missing on
R1.
