00:00:08,472 --> 00:00:11,463
- Hello and welcome to
this presentation by INE

3
00:00:11,463 --> 00:00:15,394
on Using GNS3 for Network Simulations.

4
00:00:15,394 --> 00:00:16,432
I'm Keith Bogart

5
00:00:16,432 --> 00:00:19,664
and I will be your instructor
for this series of videos.

6
00:00:19,664 --> 00:00:22,664
Now, to begin with, GNS3, what is it?

7
00:00:22,664 --> 00:00:25,396
Well, you might not even know
what the acronym stands for.

8
00:00:25,396 --> 00:00:27,770
It stands for Graphical Network Simulator

9
00:00:27,770 --> 00:00:30,355
and if you're watching
this series of videos,

10
00:00:30,355 --> 00:00:32,221
it's because you already know a little bit

11
00:00:32,221 --> 00:00:35,533
about the potential use of GNS3.

12
00:00:35,533 --> 00:00:37,263
So I'm gonna make some assumptions here

13
00:00:37,263 --> 00:00:39,253
as I start out this video series.

14
00:00:39,253 --> 00:00:42,253
Number one, I'm gonna assume
that your primary interest

15
00:00:42,253 --> 00:00:44,942
in using GNS3 is one of two things,

16
00:00:44,942 --> 00:00:47,762
either you're studying for
some sort of certification

17
00:00:47,762 --> 00:00:50,012
like a Cisco CCNA or a CCNP

18
00:00:51,391 --> 00:00:54,013
or you just wanna
practice the technologies,

19
00:00:54,013 --> 00:00:56,300
maybe you're curious about how BGP works,

20
00:00:56,300 --> 00:00:59,413
you wanna work a little bit
more with NAT or Access List

21
00:00:59,413 --> 00:01:00,303
or something like that

22
00:01:00,303 --> 00:01:03,867
and you don't really have
real equipment to work with

23
00:01:03,867 --> 00:01:05,433
and you wanna try it out on GNS

24
00:01:05,433 --> 00:01:09,001
which is a perfect platform
for that type of thing.

25
00:01:09,001 --> 00:01:10,708
So in this series of videos,

26
00:01:10,708 --> 00:01:12,006
I'm gonna start at the very beginning.

27
00:01:12,006 --> 00:01:15,000
I'm gonna show you where
to find the software,

28
00:01:15,000 --> 00:01:17,506
how to download it and
then from that point on,

29
00:01:17,506 --> 00:01:18,439
I'm gonna talk a little bit about

30
00:01:18,439 --> 00:01:21,772
okay, why does GNS use Cisco IOS images?

31
00:01:23,048 --> 00:01:24,744
When selecting an IOS image,

32
00:01:24,744 --> 00:01:26,362
what types of things should you consider

33
00:01:26,362 --> 00:01:29,995
as far as which type of
IOS image you want to use?

34
00:01:29,995 --> 00:01:33,061
And then we'll talk about
how you import the IOS images

35
00:01:33,061 --> 00:01:36,289
into GNS3, how you set up your topologies,

36
00:01:36,289 --> 00:01:38,939
and I'll give you some
examples of how to create labs

37
00:01:38,939 --> 00:01:41,504
using GNS3 and all the various things

38
00:01:41,504 --> 00:01:42,981
that go along with that.

39
00:01:42,981 --> 00:01:45,428
So follow along with me as we dive into

40
00:01:45,428 --> 00:01:48,095
the tutorial here on using GNS3.
