It's time for us to spend some time reviewing the virtualization technologies
we've discussed.
Everything from virtualized hosts and virtual machines and virtual switching,
importantly,
all the way up to talking about virtualization technology we use in networking.
So VRFs and then tunnel mechanisms, GRE, IP stack, how do we lock those down?
And then VXLAN and LISP, which importantly comes back to our conversation on
Cisco's
software-defined access, which is kind of why we're talking about VXLAN and LIS WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
software-defined access, which is kind of why we're talking about VXLAN and LIS
P.
So we do want to make sure that we can kind of close that circle here or go, go
,
go, folks, or however, want to say it, but make sure that we understand not
only how
these technologies work, but why it matters.
Now as part of this skill, what we're really going to focus on is just some
making sure
we have the knowledge, making sure we understand the concepts.
We're going to hit some quiz questions, which will help us to maybe check those
recall types
of situations.
Do I remember the different types of hypervisors, for example? WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Do I remember the different types of hypervisors, for example?
Do I remember how much MTU changes with VXLAN, those kinds of things?
And then we'll have a couple of scenarios as well, just to make sure that we
have a
little bit more of an open-ended conversation to ensure that we understand how
these concepts
come together.
The one thing we're not going to do in this skill is jump back into the lab.
And the reason for that is simply the labs that were done in those skills, we
can just
go back and do those anytime.
And so that's what I really recommend doing is in order to make sure we WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
And so that's what I really recommend doing is in order to make sure we
understand the
commands we're supposed to be running in order to deploy GRE, to deploy IPsec,
all of
that, we're not deploying VXLAN or LISP, we just need to understand those
concepts.
But for the technologies we have to configure, I highly recommend going back in
time whether
it's now or at the end of the course, whichever one you want, maybe both, but
go back to those
skills, do those labs again.
It's just absolutely mission critical that we'd be able to log into a device
and know WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
and know
how to perform those configurations.
And there's no better way to do that than by simply launching the lab and doing
those
configs.
So with that, let's go ahead and jump into some quiz questions and scenarios to
help
us drive these points home.
