Hi all,
Something very basic I have Noticed with the IGRP metric
equation I found in Doyle's book and on the link
http://www.cisco.com/warp/public/103/3.html I wanted to
share with you. The metric equation is shown as
Metric = [ K1 * Bandwidth + (K2 * Bandwidth)/(256-load)
+ K3*Delay ]*[K5/(reliability + K4)]
Now this question is for all you mathematicians here.
If K5 is 0 all what number is in the second square
brackets will be zero. So, the result of
[ K1 * Bandwidth + (K2 * Bandwidth)/(256-load) +
K3*Delay ] multiplied by zero, will be zero, unless the
* sign means something else other that multiplication.
In order to have the second square bracket to be a term,
you sign between them should be a (+), for example.
What do think??
