Which of the following commands would reveal the K values configured on an EIGRP router?
A. debug ip eigrp
B. debug eigrp packet
C. show ip eigrp traffic
D. show ip protocols
Explanation:
The show ip protocols command gives information about any dynamic routing protocol, including EIGRP. With respect to EIGRP, it will show the K values as a part of the output. A sample is shown below:
Routing Protocol is “eigrp 77”
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1,K2=0,K3=1,K4=0,K5=0
EIGRP maximum, hopcount 100
The debug ip eigrp command displays real-time information about EIGRP packets that are received and sent. It does not contain K values. A single line of this command output is shown below:
Router# debug ip eigrp
IP-EIGRP: Processing incoming UPDATE packet
IP-EIGRP: Ext 192.168.5.0 255.255.255.0 M 386560 – 256000 130560 SM 360960 – 256000 104960
The debug eigrp packet command displays general debug information, but not K values. A sample of this command output is shown below:
Router# debug eigrp packet
EIGRP: Sending HELLO on Ethernet0/1
AS 109, Flags 0x0, Seq 0, Ack 0
EIGRP: Received UPDATE on Ethernet0/1 from 192.195.78.24,
AS 109, Flags 0x1, Seq 1, Ack 0
The show ip eigrp traffic command displays packets received, as well as statistics on hello packets, updates, queries, and acknowledgments, but not K values. Partial output of this command is shown below:
Router# show ip eigrp traffic
