Hello everyone, and welcome to Protocol Deep Dive: EIGRP.
My name is Sean Wilkins,
and this is the Showing How Information Is Exchanged with EIGRP module.
This module takes the theory that was covered in the previous module
and moves it into a practical lab environment.
We begin with a demonstration of neighborship establishment,
focusing on the different packets that are initially exchanged.
We then move into a demonstration of how EIGRP devices
communicate when there is a change in the network,
including the adding and removing of different routes,
as well as device restart and reset.
Next, we move into a demonstration of external routes,
focusing on how these routes are propagated between EIGRP devices.
And we finish up with a demonstration of authentication and how
this changes the packets that are exchanged. So now with all this out of the way, let's get started.
