EIGRP Metrics

EIGRP uses these scaled values to determine the total metric to the network:

• metric = [K1 * bandwidth + (K2 * bandwidth) / (256 - load) + K3 * delay] * [K5 / (reliability + K4)]

Note: These K values should be used after careful planning. Mismatched K values prevent a neighbor relationship from being built, which can cause your network to fail to converge.
Note: If K5 = 0, the formula reduces to Metric = [k1 * bandwidth + (k2 * bandwidth)/(256 - load) + k3 * delay].
The default values for K are:

• K1 = 1
• K2 = 0
• K3 = 1
• K4 = 0
• K5 = 0
