Yes, this is the point I've been trying to make, subtly, but failing :-)

In the second terminal output box in your article, you are checking
R7's s0/0/0 interface, but the bandwidth and delay values specified
there are irrelevant.

Nice article, but if I could give one piece of feedback it would be to
make it painfully clear that the composite metric is calculated
"uni-directionally" -- from the device performing the calculation, to
the ultimate destination -- using the egress interfaces *only*,
including the ultimate directly connected interface, in each hop along
the path.  (in this case, R8's s0/0/0 and R7's lo0.)

I've found this fact to result in a 'light bulb moment' for lots of
people struggling with EIGRP metric calculation.

Cheers,
Dale
