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.
Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause
for this misconfiguration?
A.
The K values mismatch.
B.
The AS does not match.
C.
The network command is missing.
D.
The passive-interface command is enabled.
Explanation:
The link from R1 to R6 is shown below:
As you can see, they are both using e0/0. The IP addresses are in the 192.168.16.0 network:
But when we look at the EIGRP configuration, the “network 192.168.16.0” command is missing on
R6.
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 ……. Success rate is 0 percent (0/5)
