EIGRP Calculation
Hi All,
I'm struggling to understand the formula properly. What I don't understand is the BW calculation within the formula. So the EIGRP BW is "Inverse lowest BW along a path in Kbps scaled by 10^7 * 256. What does the inverse bandwidth actually mean? I don't understand.
EDIT:
Lol, I just watched like 30 seconds further in the video (after pausing it for about 30 minutes) to see that Brian just says it means 1/ the BW. Man I wish I didn't pause the video to work it out.

Good job !
The formula that you are pointing to refers to EIGRP classic mode composite metric calculation. The new EIGRP code, named mode or multi-af mode, has a different composite metric calculation.
Do you mean if you are using wide metrics? I'm not that far in the videos yet.
I'm not if this is in the INE materials - however if you register for CiscoLive a really good session on all things EIGRP is BRKIPM-2444
Hey, yes I am registered with Cisco Live, I went to the one earlier this year
I will have a look at that in a bit.
Cheers,
Steve

I'm sure the guys that wrote EIGRP had a very specific reason for structuring the formula the way they did. The inverse of the lowest BW int he path just means (1/lowerest BW in the path). For example, if the lowest BW in a path is 100Mb, then the formula is (1/100)
... and only now I'm just realizing you have figured this out for yourself... major fail lol. That's what I get for not reading the whole post.
