1
00:00.000 --> 00:03.680
So as we continue our journey here, we just created the new transport zone.

2
00:03.680 --> 00:06.720
Even though we have this transport zone, which we're going to create a segment

3
00:06.720 --> 00:07.520
and put in it,

4
00:07.520 --> 00:12.880
we need to also tell our edge devices that we want them to be included as part

5
00:12.880 --> 00:13.440
of supporting

6
00:13.440 --> 00:17.260
segments in that new transport zone. So let's also take a moment right here, go

7
00:17.260 --> 00:17.840
to both of our

8
00:17.840 --> 00:21.840
edges and say, "Hey, you know what? In addition to the overlay transport zone

9
00:21.840 --> 00:22.720
that you're supporting,

10
00:22.720 --> 00:26.860
please also support segments in this new transport zone for VLAN-backed

11
00:26.860 --> 00:28.480
segments that we just created."

12
00:28.480 --> 00:32.240
So let's make a road trip over to edge one, edge two, and we'll train them that
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

12
00:28.480 --> 00:32.240
So let's make a road trip over to edge one, edge two, and we'll train them that

13
00:32.240 --> 00:33.040
we want them both

14
00:33.040 --> 00:36.850
to support segments that are going to be put into that new transport zone. So

15
00:36.850 --> 00:37.520
to do that,

16
00:37.520 --> 00:41.830
with the system tab selected in the NSX manager, we'll head over on the left,

17
00:41.830 --> 00:42.640
expand fabric if

18
00:42.640 --> 00:48.050
it isn't already, and click on nodes, which in this flavor of NSX is referring

19
00:48.050 --> 00:49.360
to edge nodes.

20
00:49.360 --> 00:54.160
So with the nodes selected on the left, let's go ahead and start with edge one.

21
00:54.160 --> 00:54.400
So we'll click

22
00:54.400 --> 00:58.070
on edge one, and here in the overview is showing that it's currently only set

23
00:58.070 --> 00:59.600
up to support the

24
00:59.600 --> 01:04.610
overlay transport zone called our AB overlay TZ, and we want to also add on top
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

24
00:59.600 --> 01:04.610
overlay transport zone called our AB overlay TZ, and we want to also add on top

25
01:04.610 --> 01:05.840
of that our new

26
01:05.840 --> 01:10.530
VLAN-backed transport zone. So we'll click on the pencil to go ahead and edit,

27
01:10.530 --> 01:11.120
and then here for

28
01:11.120 --> 01:14.620
transport zones that's being supported by edge one, we'll just use the drop

29
01:14.620 --> 01:16.160
down and we'll add to it

30
01:16.160 --> 01:20.240
our new VLAN-backed transport zone, so now supporting both of them and we'll

31
01:20.240 --> 01:21.600
click on save. So once

32
01:21.600 --> 01:26.330
this is done, we'll do the same exact process for edge two. So we'll select

33
01:26.330 --> 01:27.600
edge two, we'll click on

34
01:27.600 --> 01:31.280
the pencil for edge two to edit it, and then here for edge two for the
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

34
01:27.600 --> 01:31.280
the pencil for edge two to edit it, and then here for edge two for the

35
01:31.280 --> 01:32.640
transport zones it supports,

36
01:32.640 --> 01:37.230
we use the drop down and say please also support segments in this new transport

37
01:37.230 --> 01:38.080
zone should they be

38
01:38.080 --> 01:41.240
created, which we'll do next, and we'll click on save. And let's verify that

39
01:41.240 --> 01:42.400
real quick, here's edge

40
01:42.400 --> 01:47.300
one, it supports these two transport zones, fantastic, here's edge two, and it

41
01:47.300 --> 01:48.800
's showing it supports those

42
01:48.800 --> 01:52.690
two transport zones as well. So that looked great, so our next step is to

43
01:52.690 --> 01:55.440
create an actual VLAN-based

44
01:55.440 --> 01:59.940
segment that will include as part of that new transport zone. So to create a

45
01:59.940 --> 02:00.720
new segment, we're
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

45
01:59.940 --> 02:00.720
new segment, we're

46
02:00.720 --> 02:04.120
going to click up here on networking on the top and on the left under

47
02:04.120 --> 02:05.600
connectivity, we'll click

48
02:05.600 --> 02:09.560
right here on segments. So here are our two overlay segments in here in the

49
02:09.560 --> 02:10.720
transport zone name

50
02:10.720 --> 02:15.470
column, it also is showing us the type. So these are two segments of type

51
02:15.470 --> 02:16.480
overlay, and we want to

52
02:16.480 --> 02:20.820
create a new one that's of type VLAN. So we'll click on add segment, and let's

53
02:20.820 --> 02:21.680
call this external

54
02:21.680 --> 02:26.000
segment 192 that way when I see it, we'll know exactly what it is, this is

55
02:26.000 --> 02:27.120
going to represent

56
02:27.120 --> 02:31.090
a VLAN-backed segment, and on that VLAN-backed segment, which I'm going to use
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

56
02:27.120 --> 02:31.090
a VLAN-backed segment, and on that VLAN-backed segment, which I'm going to use

57
02:31.090 --> 02:32.320
as VLAN-zero,

58
02:32.320 --> 02:37.200
it's my 192 168 one network. And so for the connected gateway, we're not going

59
02:37.200 --> 02:38.080
to connect this to a

60
02:38.080 --> 02:41.180
gateway now, it's a temptation right here, so you know what, let's go ahead and

61
02:41.180 --> 02:42.160
connect this to

62
02:42.160 --> 02:45.060
one of our gateways, but what we're going to do if we want fault tolerance is

63
02:45.060 --> 02:45.520
we're going to create

64
02:45.520 --> 02:49.870
the segment, and then in a separate step, we'll go ahead and associate two

65
02:49.870 --> 02:51.120
logical interfaces

66
02:51.120 --> 02:54.990
on our tier zero gateway that are both connected to this segment for fault

67
02:54.990 --> 02:56.400
tolerance, one interface

68
02:56.400 --> 03:00.120
using edge one and a second interface using edge two. So for now, we're just
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

68
02:56.400 --> 03:00.120
using edge one and a second interface using edge two. So for now, we're just

69
03:00.120 --> 03:01.440
creating the segment,

70
03:01.440 --> 03:05.750
not connecting it to a gateway, and then for the transport zone it belongs to,

71
03:05.750 --> 03:06.960
we want to specify

72
03:06.960 --> 03:11.180
our VLAN-backed TZ right here, and that's also how it knows what type of

73
03:11.180 --> 03:12.560
segment this is going to be,

74
03:12.560 --> 03:16.720
is it going to be a overly segment, or is it going to be a VLAN-based segment?

75
03:16.720 --> 03:17.760
And because we selected a

76
03:17.760 --> 03:22.070
transport zone that was of type VLAN, it now knows or is going to create this

77
03:22.070 --> 03:23.440
external segment also as

78
03:23.440 --> 03:27.770
a VLAN-backed segment. So they go ahead and collapse the left-hand side, gives

79
03:27.770 --> 03:29.120
a little bit more room,

80
03:29.120 --> 03:34.290
and now it's asking for what VLAN do we want to associate with this segment. So
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

80
03:29.120 --> 03:34.290
and now it's asking for what VLAN do we want to associate with this segment. So

81
03:34.290 --> 03:35.520
for my topology,

82
03:35.520 --> 03:40.940
I need no 802.1q tagging whatsoever, because it's on my effectively my native V

83
03:40.940 --> 03:42.000
LAN-VLAN one.

84
03:42.000 --> 03:46.440
So I'm going to put a zero here, and that simply says, okay, no tagging. So if

85
03:46.440 --> 03:48.240
we had our connectivity

86
03:48.240 --> 03:53.080
between our NSX environment and our physical network, if it was VLAN-20, we put

87
03:53.080 --> 03:54.240
VLAN-20 here.

88
03:54.240 --> 03:59.120
If it was VLAN-70, we put VLAN-70 here. In my case, I'm not using tagging on my

89
03:59.120 --> 03:59.920
192.1

90
03:59.920 --> 04:03.740
state one network. There's no 802.1q tags associated with it. So I'm going to
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

90
03:59.920 --> 04:03.740
state one network. There's no 802.1q tags associated with it. So I'm going to

91
04:03.740 --> 04:05.440
put zero to represent

92
04:05.440 --> 04:09.360
no tagging, no special VLAN assignment. And that's all the information I

93
04:09.360 --> 04:10.160
specify right here,

94
04:10.160 --> 04:14.480
the name, the fact that it's in a zone that's a VLAN-backed transport zone,

95
04:14.480 --> 04:15.120
which makes it a

96
04:15.120 --> 04:19.130
VLAN-backed segment, and then which VLAN to associate this with. And everything

97
04:19.130 --> 04:20.000
else, I'm going to leave

98
04:20.000 --> 04:23.900
as their defaults, and we're going to scroll down and click right here on Save.

99
04:23.900 --> 04:24.880
All right, so it

100
04:24.880 --> 04:28.280
created it, now it's giving us the opportunity to continue editing it. I don't

101
04:28.280 --> 04:29.040
need any further

102
04:29.040 --> 04:33.160
edits right now, so I'm going to click on No. And now we have this new segment.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

102
04:29.040 --> 04:33.160
edits right now, so I'm going to click on No. And now we have this new segment.

103
04:33.160 --> 04:33.920
Also take a look

104
04:33.920 --> 04:39.290
here. It shows that the type is VLAN-based. So this segment, external segment

105
04:39.290 --> 04:40.880
192, if we expand it

106
04:40.880 --> 04:43.920
here, it shows the details as well. It's in this transport zone, which is a V

107
04:43.920 --> 04:44.960
LAN-backed transport

108
04:44.960 --> 04:48.820
zone. And the VLAN we're using is nothing. So effectively, no tagging. So we'll

109
04:48.820 --> 04:49.840
collapse that.

110
04:49.840 --> 04:54.160
So now what do we have? We go back to System and Nodes, we have two edge nodes

111
04:54.160 --> 04:55.440
that both support

112
04:55.440 --> 05:01.400
VLAN-backed transport zone. And we also now have a VLAN-backed segment right
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

112
04:55.440 --> 05:01.400
VLAN-backed transport zone. And we also now have a VLAN-backed segment right

113
05:01.400 --> 05:02.560
here that's associated

114
05:02.560 --> 05:06.960
with this transport zone. And also this external segment is going to use VLAN-

115
05:06.960 --> 05:07.520
zero.
