Not sure what you are looking for here in the technical community ? is this a problem ?  - this is more of your learning question as per I know.

 

Suggest to visit this place explained more detail.

Hi

 K value is a representation  of more then one network parameter 

 

EIGRP composite cost metric = 256*((K1*Scaled Bw) + (K2*Scaled Bw)/(256 Load) + (K3*Scaled Delay)*(K5/(Reliability + K4)))

 

From the print you sent, reliability and delay would be represented by k3 and k4.

Bandwidth by k1. 

 

 

I do not understand the question. Perhaps what to match is understandable, but I believe that a good answer will depend on understanding where we are doing the matching and why we are doing the matching.

Not sure what you want to do?

 

if you want to know what is the K value or how can you match that k value.

 

you can change it but make sure you have TOS ( type of service value 0 ) make sure the same K value also should be on neighbors' routers as well to communicate with neighbors. 

( show ip protocols )will show you the default k value.

 

command to change K value 

router eigrp 100

matric wights 0 1 1 1 1 1     

 

where 0 present for TOS.

 

BW (k1 )= 1  Delay(k2)=1  load(k3)=1 reliability(k4)=1 MTU(k5)=1

 

 

 

 

 

Thanks,
Jitendra

@Jitendra Kumar I think your metrics are switched. While most documentation (to include CISCO Press and other CISCO documents) places these metrics in alphabetical order as you have, they are not configured in alphabeticla order on routers.

 

EIGRP Metric K Values Explained with Examples (computernetworkingnotes.com)

 

In your example: 

BW (k1 )= 1  Load(k2)=1  Delay(k3)=1 reliability(k4)=1 MTU(k5)=1

 

Load is weighted by K2 and Delay is weighted by K3.

 

@krahulbgp By default K1 and K3 are set to 1 and used in the EIGRP calculation for metrics. You can change them to whatever you want to fit your network needs as long as they match in your domain.
