The section about nbr discovery says about the hello packets that “These packets are sent over TCP”. Looking at sniffer logs, EIGRP hello packets are directly on top of IP and have IP Protocol 88.

In EIGRP bandwidth and delay you can assign manual but reliability and load is dynamic.

Be careful on the exams. Here AD is what the Cisco Official cert guide calls RD (reported distance) and it also calls AD (administrative distance)!

Quick question. On startup I believe neighbors exchange topology tables, not routing tables. I just want to make sure I understand it correctly.

EIGRP has “triggerd-updates”, which means, that it will only send update packets if the routing table changes. Or a new Router is discoverd.
It is the 5. of the features mentioned on top of the page.

Hope it will help you to understand.

clear explanation. BUT regular updates are needed. Please edit the “CISCO PROPRIETARY” routing protocol bacause now EIGRP can be implement in any vendor as far as that vendor has incorporated EIGRP into its products. Cisco has made it Informational RFC around March 2013.

By: Router47

Router47 — Wed, 04 Dec 2013 21:07:58 +0000

I am confused…

In this explanation…a “show eigrp topology” will reveal this ( / ) number…the explanation here says

“the FIRST number is the metric from Router0 to the destination while the SECOND number is the Advertised Distance”

Yet on the EIGRP ICND2 questions page, the last question makes it sound like the FIRST number is the Feasible Distance while the SECOND number is the Advertised Distance.

The explanation on this page and on that ICND2 EIGRP questions page DON’T seem to match.

What is the truth?

Great article BUT… your note about the DLY shown in the “show interface” output being in milliseconds and not microseconds is incorrect. It is indeed microseconds (µsec or 1/1000 of a ms) and the ‘u’ is as close as they could get with the µ character, I suppose, with standard ASCII. It needs to be divided by 10 in the formula, as you show, because EIGRP’s “delay” value refers to “tens of microseconds”. So, you’ll need to fix a couple graphics on this page which incorrectly refer to ‘msec’ instead of ‘µsec’
