Hello everyone, and welcome to Protocol Deep Dive: EIGRP.
My name is Sean Wilkins,
and this is a Determining How Information Is Exchanged with EIGRP module.
This module goes deeper into EIGRP communications,
specifically covering the different ways that EIGRP devices
communicate and the messages that are used.
In this module,
we begin with a section discussing the different EIGRP route states,
as well as EIGRP's use of split horizon and poison reverse.
In the next section,
we will detail the different EIGRP message and packet types that are used,
including a review of how they are used in combination with
each other to inform the EIGRP process.
In the next section, we will talk about the different common types of EIGRP TLV,
their structure, and the different situations that they are used in. So now with all this out of the way, let's get started.
