Hello everyone, and welcome to Protocol Deep Dive: EIGRP.
My name is Sean Wilkins.
In this course,
we are going to take a close look into the enhanced
interior gateway routing protocol, or EIGRP.
The purpose of this course is to take a more
hands-on approach to learning EIGRP.
This way the student will get a practical view into EIGRP,
which is often very helpful.
This course will include six different modules starting
with the Covering EIGRP Essentials module.
In this module, we will introduce EIGRP to the student,
specifically covering how it differs from other routing protocols,
as well as some basics about its operation.
In the Digging into EIGRP Relationships module,
we will move on from EIGRP basics and take a look
at how EIGRP neighborships form,
including monitoring the packets as devices are internally communicating.
In the Determining How Information is Exchanged with EIGRP module,
we will take a closer look at how information is
exchanged between EIGRP devices,
including how the alteration of certain parameters will
affect the ability to communicate.
In the Covering EIGRP Advanced Topics module,
we will take a look at some of the more advanced EIGRP topics,
including queries, stubs, and the use of router IDs.
In the Reviewing EIGRP Summary Routing and Load-Balancing module,
we will take a look at how EIGRP handles summary routing,
both automatically and manually,
as well as how it handles load balancing and how this is
different from other routing protocols.
And finally, in the Troubleshooting Common EIGRP Issue module,
we will finish up this course and discuss and
troubleshoot a number of common EIGRP issues,
including stuck in active, K-value mismatch,
and mismatch parameters, among others.
Now that we've gone over the overall structure of the course,
let's move into the contents specific to this module,
the Covering EIGRP Essentials module.
As noted previously,
this module will be a primer to EIGRP and how it fits
within the different routing protocols,
as well as some of the basics of its operation.
We will begin with a section focusing on the different types
of routing protocols that are available and where EIGRP fits
within these different options, as well as some examples of how it operates.
The second and final section of this module will move deeper into EIGRP,
specifically covering its metric, its route selection process,
and its use of a topology table. So now with all of this out of the way, let's get started.
