EIGRP Metric calculation

Eigrp metric is calculated by using the below formula:-

metric = {K1*BW + [(K2*BW)/(256-load)]+(K3*delay)}*{K5/(reliability+K4)}

By default, value of only K1 and K3 are 1 and all other K values are 0 which makes the formula as shown below:-

Note: - Mismatch in K values prevents the neighbor formation.

Metric = 256 * ( Bandwidth + delay)

Bandwidth is calculated by using below expression where BWmin is in Kbps.

bandwidth= (256 x 107)/BWmin

Delay is sum of all the outgoing interface delays which comes in the path. Delay will be taken in microseconds.

delay = [sum of delays] x 256
