Don't change the value of k1,k2,,,k5
As with IGRP, the 'K' values for the last three are defaulted to '0'.
Only the military use 'Reliability'. Most configurations use the first
two metrics Delay and Bandwidth, with Bandwidth taking precedence. The
metric for EIGRP is calculated by multiplying the IGRP metric by 256. So
the formula used to calculate the metric is EIGRP Metric = 256*((K1*Bw)
+ (K2*Bw)/(256-Load) + (K3*Delay)*(K5/(Reliability + K4))).
The default values for weights are:
K1 - 1
K2 - 0
K3 - 1
K4 - 0
K5 - 0
So
==================
K1 is bandwidth
K2 is load
K3 is reliability
K4 forgot what is it
K5 is mtu
===================
IT is NOT!
This gives the default formula of 256*(Bw + Delay) for the EIGRP metric.
You can change the weights if you want to. However, just as with IGRP,
these weights must be the same on all the routers!.
Taking the example we used when looking at IGRP, a link where the
bandwidth to a particular destination is 128k and the delay is 84000
microseconds. Using the cut down formula EIGRP metric = 256*(Bw +
Delay), we obtain the value 256*(107/128 + 84000/10) which gives
256*86525 = 22150400

Leo,
You just touched them in your formula. The minimum bandwidth and the
total
delay are K1 and K2. How come you advice not to touch them while you are
using them your self?

Metric (eigrp) = ( 10000000/minimum bandwidth + total delay ) x 256
Don't touch k1,k2 ,,, k5, you don't need to.

Router(config-router)#metric weights tos k1 k2 k3 k4 k5
K1 is bandwidth
K2 is load
K3 is reliability
K4 forgot what is it
K5 is mtu
There is a formula to calculate the metric but I do not remember it. You
have to go the Doc CD or Jeff Doyle to find out how to calculate the
metric
from this parameters.

Hi All,
I have 2 eigrp routes in the router , one through leased line & second
thrrough VSAT.
It is HUB & SPOKE technology , could you tell me how do i set the
metric at
the SPOKE or HUB so that first preffered path is leased line & second
one is
VSAT. How do i change the metric ?
