Think of it this way....
The only K values that are set to 1 are K1 and K3
which are Bandwidth and Delay. If all other values are
set to 0, then the metric calculation in Eigrp will be
dependent on the values of Bandwidth and Delay which
is a truth in Eigrp world.
To cut a long story short..... K2=K4=K5=0 means that
by default, these values are 0.
