Hello, and welcome. My name is Keith Barker.

2
00:03.600 --> 00:06.480
And I'd like you to imagine that you've gotten in your car, you're leaving your

3
00:06.480 --> 00:06.960
house,

4
00:06.960 --> 00:09.840
you go to the end of your street and normally at the end of the street,

5
00:09.840 --> 00:11.840
the intersection where you make a left or a right,

6
00:11.840 --> 00:15.200
let's imagine it's all blocked off. There's no left, there's no right,

7
00:15.200 --> 00:18.640
you can't go any further. Obviously, that's a problem because we're not going

8
00:18.640 --> 00:19.200
to get too far

9
00:19.200 --> 00:22.240
if we can't get off our local street. Well, the same problem happens with

10
00:22.240 --> 00:22.880
computers

11
00:22.880 --> 00:27.280
all over the planet if they cannot access their default gateway.

12
00:27.280 --> 00:31.200
It's sort of like the intersection that gets them off of their local street so
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

12
00:27.280 --> 00:31.200
It's sort of like the intersection that gets them off of their local street so

13
00:31.200 --> 00:31.840
packets can be

14
00:31.840 --> 00:35.490
routed to the given destinations. And because the computer's default gateway is

15
00:35.490 --> 00:36.160
so important,

16
00:36.160 --> 00:41.120
there's a whole family of protocols to help with redundancy for that first hop

17
00:41.120 --> 00:42.000
or that first

18
00:42.000 --> 00:45.670
router interface that clients use to get off their local networks. And this

19
00:45.670 --> 00:46.800
category of protocols

20
00:46.800 --> 00:53.280
is known as FHRP's or first hop redundancy protocols. So in this set of videos

21
00:53.280 --> 00:53.920
and in the skill,

22
00:53.920 --> 00:58.560
you and I get to take a look at three major examples of FHRP's and we'll walk

23
00:58.560 --> 00:59.440
through the configuration

24
00:59.440 --> 01:02.480
and verification of each of them. And at the end of the set of videos, I'll put
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

24
00:59.440 --> 01:02.480
and verification of each of them. And at the end of the set of videos, I'll put

25
01:02.480 --> 01:03.120
you my friend on

26
01:03.120 --> 01:06.480
the hands-on labs so you can practice with them yourself. So when you're ready,

27
01:06.480 --> 01:07.040
join me in the next

28
01:07.040 --> 01:10.050
video. We'll take a big picture of luck in the world of first hop redundancy

29
01:10.050 --> 01:10.720
protocols.
