To appreciate configuring EIGRP is probably best to do it. So in this video, I
'm going to walk you
through the steps of implementing the traditional flavor or traditional
configuration for EIGRP.
And also the tail end of the set of videos, I'll give the opportunity to do so.
Also,
if you'd like to, you can actually scroll down to the very end, click on the
link for the lab
if you want to walk through it with me step by step right now. So whether you
want to do it now,
or later when I assign the lab, either way is great. So this is our virtualized
environment
to starting up. Also, while this is booting up, let me point out this button WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
over here on the
right, the reset button. If you are working a lab and you do a few things and
go sideways,
whatever, and you want to start over from scratch, just open the lab up again,
click on reset here
in a few minutes. It'll reset the lab and you can restart the machines and just
go at it again.
So feel free to get some hands on practice because that's a big part of the
learning experience
to reinforce what we're talking about regarding EIGRP. And although this may
not be the first time you
used our virtual lab environment, it may be the first time that I've walked you
through using one.
So let me take a moment and give you the lay of the land regarding the lab
environment. So over here, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
environment. So over here,
we have lab controls. If you want to launch RDP in a separate application and
connect to the lab
environment, you can do so using that for the address right there. And then the
username is learner.
And then this dynamic password will be generated for you and it'll be different
for each of your
lab environments. But if you want to copy and paste those into RDP, if you want
to use that instead,
you can't or if you want to use the web interface, that's great too. So to
begin with,
we have server one nug here and that is going to be the VM that we're going to
launch. And it has
multi tab putty running and ready to go. So you can work with all of the rout WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
multi tab putty running and ready to go. So you can work with all of the rout
ers in the topology.
And just to confirm that, I'm going to go ahead and highlight server one here.
In fact, I need to double
click on server one and go ahead and give that just a moment to launch. So
there it goes. That was
about 15 to 20 seconds of real time. So this is server one that we're looking
at right here. And it
has multi tab putty open. So here's R1, here's R2, R3, etc. There's also tab
for PC. It's the virtual
PC and PC7 and PC8. And then for convenience, I have in the skill, I've got the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
PC and PC7 and PC8. And then for convenience, I have in the skill, I've got the
lab topology, but I
also put it right here as well. So here's an icon for the lab topology. If we
double click on that here
on server one, that's going to open that up so we can reference it here as well
. And what a lot of
people will do, they'll go ahead and download the topology right from the skill
. And then if you have a
second screen, it's really handy to put down the second screen. So you can see
your command line,
you can see the topology without having to go back and forth. But either way,
it's great. So there's
R2, I'm going to minimize that. And then here for this lab, I've got a notepad
document sitting on
the desktop. And that notepad document is called EIGRP configs right there. I WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
the desktop. And that notepad document is called EIGRP configs right there. I
also have it open by
default. So it's already open in the taskbar. And there it is. And that way it
's not a typing
exercise for you, but rather just a way to see the config, put it in, and then
also remove it as
needed. So this first section here is going to first I'll go through and remove
various versions of
EIGRP and OSPF, whether they're there or not. This is going to get rid of those
. And then to implement EIGRP,
we're simply going to do this. In fact, let me make this a bit bigger. Let me WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
we're simply going to do this. In fact, let me make this a bit bigger. Let me
go to format and font.
And I'll make this a little bigger for the recording. So let me go ahead and go
to 20 and click on OK.
That's better. All right. So the actual configuration for EIGRP is from
configuration mode. You just
go into router EIGRP, give it an autonomous system number. And then this
network statement effectively says
any interfaces that have an IPv4 address, you're in. That's it. So that's what
I'm going to do on all
the routers. I'm going to go ahead and copy that little piece right there. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
the routers. I'm going to go ahead and copy that little piece right there.
Right click. I'll copy that's
my buffer. And then I have the tab open for multi tab putty right here. So we
'll go back to multi tab
putty. And then this is really fun and cool. And I want to share it with you
right now. This icon
right there. If we click on that, we can actually choose to send the commands
to multiple devices at
the same time. So if we have configuration, which we're about to do and you
want to do it on all
devices, you just copy paste it in, you know, tab by tab by tab or we could use
this option as well.
So let's go ahead and click on that. And then from my clipboard, I'm going to WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So let's go ahead and click on that. And then from my clipboard, I'm going to
click here in this
space, type your script right click and click on paste. And that puts in that
same configuration. So
it's going to wipe out any possible earlier versions of EIDR, PROSPFI may have
had. And then it's
going to implement router EIDR P18 and a network statement of all zeros
effectively saying any
interface that have an IPV4 address, bring them in. And then I'm going to go
ahead and have it say
end. And then I click here on select all. But I don't want to send this to the
PCs because I'm not
going to know what to do with those commands. So I'm simply going to remove PC WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
going to know what to do with those commands. So I'm simply going to remove PC
one PC seven PC eight
and send those commands to all of the eight routers. So if that in place, I'll
click send script.
And now it's done that for all eight routers. And because EIDR P is so quick,
it's already negotiated
neighborships, it's already converged. And each of the routers in the topology,
let me bring up the
topology again. They should now know how to reach every single IPV4 network in
this topology.
So as a quick test, let's go to R1. So R1 is at the top left hand corner of our WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So as a quick test, let's go to R1. So R1 is at the top left hand corner of our
topology. And let's
start off the show IP protocols. We'll see what IPV4 protocols are running. So
here it's showing us,
I'll scroll up a little bit here. Here's showing us the EIDR P, autonomous
system 18 is running.
And here's showing us the metric weights that are being used. So K1 is the
minimum bandwidth in the
path. And K3 is the sum of the delays, meaning the delays added up. And the
other values, the other
K values, which represent things such as load and reliability and M2U. Those WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
K values, which represent things such as load and reliability and M2U. Those
are not being used for
the metric calculation. It's also showing us here, let me bring up the topology
once again for this.
And I'll just move it a little bit over to the right. Here it's also showing us
that router 1, the
current router that we're sitting at, is learning routing updates and routing
information from R3,
based on that last octet of dot 3. And also from dot 2, based on the last octet
ending in dot 2.
That's another thing I did in the topology is to make it easy, I just used the
router number for
the final octet for each of the interface IP addresses. So here on R1, we have
to show IPEIDR WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
to show IPEIDR
ERP neighbors. It'll show us who our neighbors are. There's R2 and R3, off of
the respective interfaces.
And then we do a show IPEIDGRP interface. It'll show us which interfaces are
enabled for EIDGRP,
which are all the interfaces that are using IPV4 on router 1. We can also show
IPEIDGRP topology.
Now before I press enter on this one, there's a lot of output that's going to
be shown. So let's
just focus on, for example, one route. Let's go ahead and choose the 888 route WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
just focus on, for example, one route. Let's go ahead and choose the 888 route
right here. I'll highlight
it. So for the 888 route, that 32-bit network, it has one successor. That means
one winning route in
the routing table. The feasible distance, which is the effective metric for
that route, is,
looks like 40 million in change. Let me do a quick check. That's three
characters and three more.
Now depending on the flavor and implementation of EIDGRP, it may be using mic
roseconds or
picoseconds as part of the calculation. So that is going to be a 40 there, and
that's 40 million.
So this feasible distance for the successor route, effectively, that's the WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So this feasible distance for the successor route, effectively, that's the
metric further out.
It's once again shown right here. It's also showing us the reported distance
that's coming in from
the neighbor. And based on the router it came from, the .3 there, that's R3
that has this
advertised distance. Now the fact of the matter is, R3 really isn't sending
this number. R3 is
setting information, including the sum of the delays and the slowest link in
the path. And then it's
actually R1 is calculating this number based on those considerations, based on
the reported
distance. So again, this first number here is the full metric or feasible WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
distance. So again, this first number here is the full metric or feasible
distance from the perspective
of R1 to get to 8888. And the second part here is the reported distance that
was coming in from
R3. Or at least the values such as the sum of the delays and the slowest link
in the path that
were advertised by R3. And if you want to see the routing table, we can do a
show IP route.
And that shows all routes. Or if you want to see the EIGRP learned routes only,
we do a show IP
route, EIGRP, press center. And there once again is our 8888 route. And right
there is the metric
war in the world of EIGRP. We could call it the feasible distance. Or we could WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
war in the world of EIGRP. We could call it the feasible distance. Or we could
call it the composite
metric. That's the metric for that winning route. And here is the
administrative distance of 90 for
an internally learned EIGRP route. And if we wanted to verify the path, we
could do things like
trace. So we can do a trace. And we'll go ahead and trace down to 8888. Press
center. And that's
showing us that it's taking the first top and then bring up the topology. So
here based on our trace,
R1 is forwarding it over to R3 based on that 3 there. And then our 3 is using
this path to go
ahead and send it down to R8. And R8 is the owner of that local loopback of 888 WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
ahead and send it down to R8. And R8 is the owner of that local loopback of 888
8. And if you want to see
the router config again, we do a show, run, flip pipe section. And let's go
ahead and type in
router. Give that a minute to process. And there is our full routing config
right there. Router EIGRP 18.
And please include any interfaces if they have an IPv4 address of any type
associated with them.
And very similar to OSPF, we could also specify certain ranges of interfaces
based on IP addresses
by using a network statement in combination with a wildcard mask. As an example WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
by using a network statement in combination with a wildcard mask. As an example
of that, let's go
ahead and do a no. And then simply get a copy paste router EIGRP 18. Paste that
in. Do a do show
IP EIGRP interface. So no interfaces are participating at the moment in EIGRP.
So we'll go ahead and do
router EIGRP. And we'll set the same time system 18. And how about anything it
starts with 10. So
we're going to do 10.0.0.0. And then a wildcard mask of 0. And then if we don't
care about the second,
third and fourth octet, we do 255 for wildcard bits there, 255 for wildcard WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
third and fourth octet, we do 255 for wildcard bits there, 255 for wildcard
bits there, and 255
and press enter. And then if we hit the up here a few times, and today show IP
EIGRP interface,
we'd only get those interfaces that start with a 10. And that does not include
the loopback
interface because the interface loopback in our one starts with a 1 and not a
10. But if we want
to add that also, we could do a network 1.1.1.1. Press enter, it's assuming the
exact address. If you don't
use wildcard bits, now if we do a show IP EIGRP interface, it now includes loop
back 0 as well. If we do
a do show IP interface brief, and say please exclude unassigned, that will also WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
a do show IP interface brief, and say please exclude unassigned, that will also
show us the associate
IP addresses on those interfaces. So it's like an end there. So that's an
example of how we can configure
EIGRP using the traditional method. And once again, if you don't want to wait
till the end, the
lab assignment, if you want to launch that lab now, you can actually do this
right now, and then
join me in the next video as we continue because the next step is we're going
to remove this configuration
of traditional EIGRP and I like to walk you through implementing EIGRP using WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
of traditional EIGRP and I like to walk you through implementing EIGRP using
named EIGRP. So also,
you my friend in the next video for exactly that.
