00:00:08,050 --> 00:00:11,770
Hello, and welcome to
troubleshooting BGP.

4
00:00:11,770 --> 00:00:14,920
In this troubleshooting scale,
what we're going to be doing

5
00:00:14,920 --> 00:00:18,100
is going through a series
of troubleshooting tickets

6
00:00:18,100 --> 00:00:21,680
and trying to solve
problems on our equipment.

7
00:00:21,680 --> 00:00:25,240
Now, these tickets are not
going to be end user type

8
00:00:25,240 --> 00:00:28,540
tickets, of course, because
they're network-related issues,

9
00:00:28,540 --> 00:00:31,030
they're going to be more
like maybe tickets you

10
00:00:31,030 --> 00:00:34,300
would get from tier 1
or maybe a junior admin,

11
00:00:34,300 --> 00:00:35,540
that sort of thing.

12
00:00:35,540 --> 00:00:38,950
It's going to be things like
BGP neighborships aren't working

13
00:00:38,950 --> 00:00:41,590
or we're not getting
this route on this router

14
00:00:41,590 --> 00:00:43,660
that we're supposed to
have in a certain way

15
00:00:43,660 --> 00:00:45,830
or something along those lines.

16
00:00:45,830 --> 00:00:49,390
So we're going to go through
some very common BGP issues,

17
00:00:49,390 --> 00:00:51,950
take a look at how
to troubleshoot them.

18
00:00:51,950 --> 00:00:54,860
Now keep in mind as we jump in.

19
00:00:54,860 --> 00:00:58,690
A lot of times, console
messages and log messages

20
00:00:58,690 --> 00:01:01,960
are going to give us a
lot of information as far

21
00:01:01,960 --> 00:01:03,730
as troubleshooting these issues.

22
00:01:03,730 --> 00:01:08,170
And we're going to not use
those, at least not at first.

23
00:01:08,170 --> 00:01:11,450
We may revert back to looking
at them at some point,

24
00:01:11,450 --> 00:01:14,230
but the fact of the
matter is sometimes

25
00:01:14,230 --> 00:01:16,960
for some of these issues it
would just put the problem

26
00:01:16,960 --> 00:01:19,120
right in our face, and
there wouldn't really

27
00:01:19,120 --> 00:01:20,650
be too much to troubleshoot.

28
00:01:20,650 --> 00:01:23,270
And normally, that
might be a good thing.

29
00:01:23,270 --> 00:01:26,620
However, since this is an
educational experience,

30
00:01:26,620 --> 00:01:29,170
we want to go through
and look at other things

31
00:01:29,170 --> 00:01:32,450
that we can see that would
show us the same problem.

32
00:01:32,450 --> 00:01:34,960
So just keep that in
mind that normally when

33
00:01:34,960 --> 00:01:37,510
you're troubleshooting, one
of the first things to do

34
00:01:37,510 --> 00:01:42,070
is check your log files and
check any console messages,

35
00:01:42,070 --> 00:01:44,800
again, assuming you happen to
be logged into the equipment

36
00:01:44,800 --> 00:01:46,640
while the problems
are occurring.

37
00:01:46,640 --> 00:01:49,900
So all of that said, we're going
to jump into these tickets.

38
00:01:49,900 --> 00:01:51,670
We're going to go
through them one by one,

39
00:01:51,670 --> 00:01:53,800
and we're going to
solve the issues

40
00:01:53,800 --> 00:01:55,810
that we're seeing in BGP.

41
00:01:55,810 --> 00:01:57,890
So this should be a lot of fun.

42
00:01:57,890 --> 00:02:01,170
I'll see you in
the first ticket.

43
00:02:01,170 --> 00:02:04,000
