- [Keith] So in this video we're going
to resume with where we left off.
And this is part two, so in this particular case
we're going to be adding our IP addresses
to all of our interfaces, and we're gonna be
creating those loopback interfaces
and adding IP addresses to that as well.
Okay, so starting with the topology
that we already created in the first section,
let's go ahead and add our IP addresses to this.
So I'm just gonna go ahead and turn on
all the routers, at this point, simultaneously,
because I only have four routers
and it's okay to turn that many on at once.
If I had a larger topology of eight
or nine routers, I'd probably wanna
do them one at a time.
And also, I'm gonna want this to use SecureCRT,
so I'm gonna go to Edit, and Preferences,
to make sure I can use the tabbed
advantages of SecureCRT.
And right now,
that is already set up.
So we can see here,
under Console applications for Telnet,
it is using SecureCRT and it's got all the
correct arguments to do tabbing and everything else.
So we're okay there.
So hit OK, and let's just go ahead and verify
all these routers are, indeed, running.
Because I can see here in the Topology Summary
they're all green.
That's what I wanna see.
So now I should be able to start them all up.
So go ahead and,
I'm gonna Console connect to every single
one of them, all at the same time,
rather than hitting them individually.
And there we go.
Alright now, for whatever reason, SecureCRT,
when it opens up, it doesn't put the
tabs in the order I would actually like.
I want to be numerical, you know,
one, two, three, four.
So I'm just gonna move my routers around
a little bit here,
to get them where I want them to be.
Okay, let's just start with router one.
I'll go ahead and expand him for a moment.
Let's create the loopback interface first.
(keyboard clacking)
and then interface serial 2/0,
(keyboard clacking)
Don't, do not have to put a clock rate
as if these were real routers.
Because,
in GNS3,
we don't have to worry about that.
(keyboard clacking)
Alright, so that takes care of the
IP information for router one.
Let's go ahead and save his config,
because we're also going to be using
snapshots as we go along this process
so we can go back and forth in time
if we need to change things or troubleshoot things.
So, save his configuration,
let's go ahead and minimize him.
And let's now go to,
Ah, so, for some reason it moved these around.
Tryin' to get me in trouble, here.
Alright, now let's go to router two.
(keyboard clacking)
Interface serial 2/0,
that connects back to router one.
(keyboard clacking)
And interface serial 2/1, that connects to router four.
(keyboard clacking)
And that's, pretty much, all we have to do
as far as IP addressing is concerned on that router.
And make sure we save our configuration there, as well.
I love how it keeps moving my windows
on me when I expand and then contract.
That's just,
so adorable of SecureCRT.
Okay, so let's go ahead and go to router three now.
(keyboard clacking)
Interface fast Ethernet 0/0 which connects
back to router one.
(keyboard clacking)
And interface fast Ethernet
let's see, I forgot so let's go back to GNS3.
It's fast Ethernet 0/1 here, which is
the other interface that we wanna configure.
(keyboard clacking)
Save his configuration.
I'm just gonna go ahead and close that window
because I can't have the window up,
anyway, when I create a snapshot.
Because all the routers have to be powered off.
(mouse clicking)
And the last router we need to configure,
is router four.
(keyboard clacking)
And let's finish off the IP addressing, here.
(keyboard clacking)
And let's just verify that he's
got all the correct IP addresses.
Show IP interface brief.
We got our two physical interfaces
and we have our loopback, everything looks good.
So let's save the configuration, here.
Let's go ahead and shut down SecureCRT.
And let's go ahead and use some
of these other tools here to just
include what we've done so far.
So let's go ahead and use the Add a note tool
to now put in out IP addresses in subnet.
So we can keep that in track.
So, 1.2.1.x/24
That looks good.
Now let's go ahead and duplicate that four times.
(mouse clicking)
Alright, this one over here.
We're gonna right click on it and do Text edit.
(mouse clicking)
and that one is going to be
2.4.2.x
This one down here,
we'll right click on that and Text edit,
1.3.1.x
(keyboard clacking)
And this one down here,
will be 3.4.3.x.
Okay, and let's go ahead and use the
add an ellipse tool, or Draw an ellipse
to represent our loopbacks that we've created.
We'll put one right here and then
we'll right click that and hit Duplicate.
And then we'll drag the new one over here.
And then, once again, we'll use
the Add a note tool to actually draw inside there.
Loopback 0,
11.11.11.1
Duplicate,
and Edit.
(keyboard clacking)
Alright so that gives us everything
we've done, now, from an IP perspective.
So let's go ahead and save our project
as it is.
And at this point, let's go ahead
and create a snapshot, now, of where we are
with all of our IP addresses intact.
Before we start adding routing protocols onto this.
So I'm gonna create a snapshot,
Create.
And I'm gonna say IP
addresses
only
Close.
(surprised exclamation)
Ah, but I broke the cardinal rule
the cardinal rule of snapshots, which is
The routers must be in a powered
down state when you do the snapshot.
That snapshot I just took might not even work.
So let's turn everything off.
Let's create a snapshot again.
I'll give it the exact same name.
IP-addresses-only
And then the one with the earlier time stamp,
I will get rid of that.
There we go.
Alright.
And that concludes this section of the video.
In the next section we're gonna, finally,
start adding EIGRP to this topology.
