Re: EIGRP K values

HI Nicky,
  
  The K values will be used for the following calculation
  
    metric = [K1*bandwidth + (K2*bandwidth)/(256 - load) + K3*delay] * [K5/(reliability + K4)]
  
  So if you have K1 and K3 value as 1 and rest all as 0, the metric calculation will be done based on BW and Delay.

I have a little doubt about EIGRP K values that I would like to clear up.

From what I understood, the default K values 10100, representing
K1=bandwidth/K2=delay/K3=Reliability/k4=Load/ k5=MTU repectfully.

This order does not see correct to me. I thought that bandwidth and delay
were considered by default by EIGRP............and I know that delay does
affect the EIGRP metric, as can be seen from manipulating the delay
interface variable.

So, is it Bandwidth/Load/Delay/MTU/reliability

If we want to change the defaults to make bandwith 3 times and add
reliability we use metric weights 031100. This would indicate it is
bandwidth/reliabilty/delay?

I think my confusion stems from a mixup with how you specify the default
metrics for redistribution.

redistribute ospf 1 metric 10000 100 255 1 1500 ( bandwidth,
delay,reliability,load,MTU),

They are not equal eh?

Some clear simple explaination would be nice!
