Good question!! Not sure this is what you're looking for but it also says that it is based on five criteria, bandwidth and delay are the default criteria; reliability, loading and MTU are additional criteria are NOT RECOMMENDED FOR USE because they result in frequent recalculation of the topology table.

According to Cisco, the metric calculation for IGRP is (EIGRP being the same except times 256): (K1*Bw) + (K2*Bw)/(256-Load) + (K3*Delay)*(K5/(Reliability + K4)) But then other stuff I've read says that (E)IGRP metric is calculated using Bandwidth, Load, Reliability, Delay, and MTU. For instance to set a default metric the command is: default-metric Cisco has a page on redistribution that says: "IGRP and EIGRP need five metrics when redistributing other protocols: bandwidth, delay, reliability, load and maximum transmission unit (MTU) respectively." So according to the formula above, where does MTU come into play?!?!?!? Am I missing something?!?!? If MTU isn't part of the metric calculation, why bother putting it in when setting default metrics or redistributing other protocols into (E)IGRP? I know this is a pretty "basic" question, but I was just reviewing some stuff and came across this. Mike W.
