Eigrp Metric Calculation

Metric = (107 / minimum bandwidth) + (sum of delays) * 256

Metric = bandwidth (slowest link) + delay (sum of delays)

Bandwidth: [107 / minimum bandwidth in the path]

Delay: sums of delays (in tens of microseconds).

1. Bandwidth [107 / minimum bandwidth in the path]

? ? 10000000/1544 == 6476

 

2. ?Delay: sums of delays? (in tens of microseconds).

? ? ?20000 + 20000 = 40000

? ? ?40000 / 10 = 4000? ?( Divide by 10 because delay in? usec )

 

3. Metric = (107 / minimum bandwidth) + (sum of delays) * 256

? ? 4000 + 6476 * 256 =2681856
