Subject: RE: EIGRP metric (just to be sure)
Danny,
Bandwidth, load, delay, and reliability make up the composite metric. By default, only bandwidth and delay are taken into account. In order to consider load or reliability, you must weight those corresponding K values with the 'metric weights' command under the EIGRP process.
The calculation is as follows:
metric = [k1 * bandwidth + (k2 * bandwidth)/(256 - load) + k3 * delay]
If k5 does not equal zero, an additional operation is performed:
metric = metric * [k5/(reliability + k4)]
For more detail see:
