Divide the larger metric path by the smaller metric
path.
The variance command is related to the eigrp metric
calculation.
"...If k5 equals 0, the composite IGRP or EIGRP metric
is computed according to the following formula:
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)]
Bandwidth is inverse minimum bandwidth of the path in
BPS scaled by a factor of 2.56*1012. The range is from
a 1200-bps line to 10 terabits per second. ..."
The variance command is a multiplier for what you
consider a valid path for load balancing. If your
metric were 3, you would be saying that the router can
load balance any paths with a metric that is up to 3
times the metric of the path with the lowest metric.
