EIGRP Basics (K-Values)

EIGRP is a distance-vector protocol, meaning it uses variables in a path to determine the cost of getting to various networks. K-values represent the variables:

K1 – Bandwidth:

K2 – Load: 

K3 – Cumulative delay:

K4 – Reliability:

K5 – MTU (not used int route calculations)

By default, only bandwidth and delay are used, however, you can change that and utilize all K-Values but its strongly discouraged:

Configuration to change the K-Values:

Router3#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router3(config)#router eigrp 1
Router3(config-router)#met
Router3(config-router)#metric wei
Router3(config-router)#metric weights 0 1 1 1 1 1

*** Remember to match the k-valueconfiguration across all EIGRP neighbors otherwise you no neighborships will be created.
