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:-
values are 0 which makes the formula as shown below:-
Note: – Mismatch in K values prevents the neighbor
formation.
formation.
|
Metric = 256 * ( Bandwidth + delay)
|
Bandwidth is calculated by using below expression where
BWmin is in Kbps.
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.
of all the outgoing interface delays which comes in the path. Delay will be
taken in microseconds.
|
delay = [sum
of delays] x 256 |
