Re: EIGRP metrics on Doc CD

It looks to me that K sections are not grouped correctly on cisco doc page.
The right one is on wikipedia:
http://en.wikipedia.org/wiki/EIGRP
Additionally, it looks exactly as formula presented by Narbik in his class :)

I think its correct

after the values formula will cut down to

the EIGRP metric calculation would simplify to 256*(Bw + Delay), resulting
in the following value:

example: Metric = 256*(10^7/128 + 84000/10)= 256*86525 = 22150400

bandwidth formula = (10^7/minimum Bw in kilobits per second)
