00:00:03,824 --> 00:00:07,170

00:00:07,170 --> 00:00:10,560
Welcome to
Troubleshooting IS-IS.

4
00:00:10,560 --> 00:00:13,440
This skill is going to be
formatted just a little bit

5
00:00:13,440 --> 00:00:17,850
differently from how we normally
do a skill in that we're

6
00:00:17,850 --> 00:00:20,730
going to take what would
normally be a perfectly

7
00:00:20,730 --> 00:00:23,260
working IS-IS environment.

8
00:00:23,260 --> 00:00:25,530
In fact, it's the
same environment

9
00:00:25,530 --> 00:00:28,980
that we've been working with
in all of the previous IS-IS

10
00:00:28,980 --> 00:00:30,000
skills.

11
00:00:30,000 --> 00:00:34,140
And we're going to look at that
with some problems introduced

12
00:00:34,140 --> 00:00:36,000
into the topology.

13
00:00:36,000 --> 00:00:39,690
Then we're going to work through
a series of trouble tickets

14
00:00:39,690 --> 00:00:43,030
to fix these problems
in our environment.

15
00:00:43,030 --> 00:00:45,480
Now, these tickets are
going to be formatted

16
00:00:45,480 --> 00:00:49,950
sort of like they're coming from
junior engineers or maybe tier

17
00:00:49,950 --> 00:00:52,920
one tech support,
not really coming

18
00:00:52,920 --> 00:00:54,850
from the users themselves.

19
00:00:54,850 --> 00:00:57,900
So they'll be a little bit more
specific than just something's

20
00:00:57,900 --> 00:00:59,010
not working.

21
00:00:59,010 --> 00:01:01,860
They'll be things like
maybe a neighborships down,

22
00:01:01,860 --> 00:01:04,110
or we're supposed to
have a certain route

23
00:01:04,110 --> 00:01:06,280
on a certain router,
and we don't have it.

24
00:01:06,280 --> 00:01:08,940
So that's how the tickets
will be formatted.

25
00:01:08,940 --> 00:01:11,400
So as we go through
here, hopefully, we'll

26
00:01:11,400 --> 00:01:15,450
get a lot of hands-on skills
with troubleshooting IS-IS

27
00:01:15,450 --> 00:01:18,120
as we try to get our
environment back up

28
00:01:18,120 --> 00:01:21,190
and running and working
as it's supposed to.

29
00:01:21,190 --> 00:01:23,920
So again, this should
be a lot of fun.

30
00:01:23,920 --> 00:01:25,600
Let's go ahead and jump in.

31
00:01:25,600 --> 00:01:28,910
I'll see you in the next video.
