Hello, and welcome to
troubleshooting OSPF.

4
00:00:10,480 --> 00:00:12,730
In this skill, we're
going to be taking

5
00:00:12,730 --> 00:00:16,190
a slightly different approach
from what we normally do.

6
00:00:16,190 --> 00:00:20,890
We're going to be jumping into
a completely functional OSPF

7
00:00:20,890 --> 00:00:25,640
topology with, well, some
problems introduced into it.

8
00:00:25,640 --> 00:00:27,280
So what we're going
to do is we're

9
00:00:27,280 --> 00:00:30,640
going to actually work through
a series of trouble tickets

10
00:00:30,640 --> 00:00:32,560
that are going to
describe the problem,

11
00:00:32,560 --> 00:00:35,500
and then we're going to jump
in, find out what's wrong,

12
00:00:35,500 --> 00:00:37,780
fix it, and get it working.

13
00:00:37,780 --> 00:00:41,410
Now, these trouble tickets,
just so we're clear,

14
00:00:41,410 --> 00:00:42,850
are going to be
more like they're

15
00:00:42,850 --> 00:00:47,980
coming from, say, junior
admins or maybe tier 1 support.

16
00:00:47,980 --> 00:00:51,970
These aren't going to be
end-user-type tickets.

17
00:00:51,970 --> 00:00:55,210
So they're going to be a little
bit more specific than just

18
00:00:55,210 --> 00:00:57,940
it's not working, which
is probably what we would

19
00:00:57,940 --> 00:01:00,590
get from our average end user.

20
00:01:00,590 --> 00:01:02,620
So it's going to be a
little more specific,

21
00:01:02,620 --> 00:01:05,770
like a neighborship is down
between two particular routers

22
00:01:05,770 --> 00:01:07,162
or that sort of thing.

23
00:01:07,162 --> 00:01:09,370
It'll still be a little bit
generic in that it's just

24
00:01:09,370 --> 00:01:12,790
going to be a statement saying
that a neighborship's down,

25
00:01:12,790 --> 00:01:15,860
no indication as to why
or anything like that.

26
00:01:15,860 --> 00:01:17,710
So we're going to go
through these tickets.

27
00:01:17,710 --> 00:01:19,252
We're going to get
everything back up

28
00:01:19,252 --> 00:01:22,960
and working in our currently
broken OSPF topology.

29
00:01:22,960 --> 00:01:25,270
And then we'll test
everything, make

30
00:01:25,270 --> 00:01:27,640
sure it's working because
if we don't verify it,

31
00:01:27,640 --> 00:01:28,850
we didn't fix it.

32
00:01:28,850 --> 00:01:30,650
So let's go ahead and jump in.

33
00:01:30,650 --> 00:01:33,810
I'll see you in the next video.

34
00:01:33,810 --> 00:01:37,000
