00:00.000 --> 00:02.640
All right, so as part of our game plan, our next step

2
00:02.640 --> 00:06.240
is to go ahead and create a couple of external VLAN

3
00:06.240 --> 00:10.360
backed network segments, one over here with VLAN 23 for site

4
00:10.360 --> 00:13.720
1 and one for VLAN 24 over here at site 2.

5
00:13.720 --> 00:15.680
And then with those external segments in place,

6
00:15.680 --> 00:18.240
when it comes time to create the tier 0 gateway,

7
00:18.240 --> 00:20.600
we can logically associate a couple interfaces

8
00:20.600 --> 00:23.920
with the site 1, VLAN 23 address space, which we're

9
00:23.920 --> 00:27.400
going to use 23.1.2.0 with a 24-bit mask.

10
00:27.400 --> 00:30.480
And then the same thing over here for the tier 0 interfaces

X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

10
00:27.400 --> 00:30.480
And then the same thing over here for the tier 0 interfaces

11
00:30.480 --> 00:31.720
over at site 2.

12
00:31.720 --> 00:34.560
But this time we'll use VLAN 24 with each edge

13
00:34.560 --> 00:38.440
having a different IP address on the 24.1.2.0 network.

14
00:38.440 --> 00:39.760
All right, with that in mind, let's

15
00:39.760 --> 00:41.640
create our two external segments.

16
00:41.640 --> 00:44.200
So once again, we'll return to the global manager

17
00:44.200 --> 00:45.200
to do that work.

18
00:45.200 --> 00:48.080
So back here at the global manager, with it selected,

19
00:48.080 --> 00:50.360
we'll click on the networking tab at the top.

20
00:50.360 --> 00:52.120
And then we'll go down to segments,

21
00:52.120 --> 00:54.000
and we'll create our two external segments.

22
00:54.000 --> 00:58.360
And we also could go directly right from here to site 1 and site 2

23
00:58.360 --> 01:00.560
at those local managers and create them.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

23
00:58.360 --> 01:00.560
at those local managers and create them.

24
01:00.560 --> 01:03.000
But by doing it here at the NSX global manager,

25
01:03.000 --> 01:04.080
I also can give you the opportunity

26
01:04.080 --> 01:07.400
of seeing how we can associate those VLAN-backed external

27
01:07.400 --> 01:09.160
segments with the correct site.

28
01:09.160 --> 01:10.880
So that's another benefit of doing it here

29
01:10.880 --> 01:12.120
from the NSX global manager.

30
01:12.120 --> 01:13.000
It's convenient.

31
01:13.000 --> 01:15.400
And also, in the demo, I can walk you through how it's done.

32
01:15.400 --> 01:17.360
So with segments selected here on the left,

33
01:17.360 --> 01:19.560
we'll go ahead and click on Add Segment.

34
01:19.560 --> 01:21.600
And let's make the first one for site 1.

35
01:21.600 --> 01:24.200
We'll call it site 1, ext for external,

36
01:24.200 --> 01:26.880
and I'll put v23 to remind myself of the VLAN.

37
01:26.880 --> 01:28.840
So that'll be the name for this external segment.

38
01:28.840 --> 01:30.080
It's going to be VLAN-backed.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

38
01:28.840 --> 01:30.080
It's going to be VLAN-backed.

39
01:30.080 --> 01:32.880
If we scroll down, we can then specify where this should belong.

40
01:32.880 --> 01:36.520
So from the dropdown under locations, we'll choose site 1.

41
01:36.520 --> 01:40.160
Then it automatically populated the default VLAN-backed transport

42
01:40.160 --> 01:41.720
zone, associate with site 1.

43
01:41.720 --> 01:43.360
And that's why that shows up here.

44
01:43.360 --> 01:44.680
So that's fantastic.

45
01:44.680 --> 01:46.200
And then over-count the right, where

46
01:46.200 --> 01:48.240
they're going to specify the actual VLAN.

47
01:48.240 --> 01:51.520
So if this is for VLAN 23, over here for VLAN,

48
01:51.520 --> 01:53.000
we'll put VLAN 23.

49
01:53.000 --> 01:55.160
And we'll scroll down, and we'll click on Save.

50
01:55.160 --> 01:56.680
And then we'll click on No.

51
01:56.680 --> 01:59.360
And now we have this external segment associated.

52
01:59.360 --> 02:01.520
Let me collapse the left-hand column here.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

52
01:59.360 --> 02:01.520
Let me collapse the left-hand column here.

53
02:01.520 --> 02:04.520
And that segment is associated with site 1.

54
02:04.520 --> 02:05.720
So let's repeat that process.

55
02:05.720 --> 02:07.480
In fact, I'm going to go ahead and copy the name here

56
02:07.480 --> 02:09.720
so I can get a very similar syntax.

57
02:09.720 --> 02:13.520
And let's create another external segment for VLAN 24.

58
02:13.520 --> 02:15.360
And we'll associate that one with site 2.

59
02:15.360 --> 02:17.160
So we'll click again on Add Segment.

60
02:17.160 --> 02:20.400
I'll right-click and paste to keep my naming consistency.

61
02:20.400 --> 02:23.080
And then we'll call those one site 2.

62
02:23.080 --> 02:25.120
And it'll be VLAN 24.

63
02:25.120 --> 02:27.600
And then this will be at the location from the dropdown.

64
02:27.600 --> 02:29.160
We'll choose site 2.

65
02:29.160 --> 02:30.760
And then for the transport zone, it's
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

65
02:29.160 --> 02:30.760
And then for the transport zone, it's

66
02:30.760 --> 02:33.120
choosing the default VLAN-backed transport zone, which

67
02:33.120 --> 02:33.960
is perfect.

68
02:33.960 --> 02:37.320
And then over here in VLAN, we'll specify it as VLAN 24.

69
02:37.320 --> 02:39.960
And we'll scroll down and click on Save.

70
02:39.960 --> 02:41.040
And we'll click on No.

71
02:41.040 --> 02:44.000
So now we have our two external segments.

72
02:44.000 --> 02:46.000
The first one being associated with site 1.

73
02:46.000 --> 02:48.040
If we scroll down, the second one here

74
02:48.040 --> 02:49.960
is associated with site 2.

75
02:49.960 --> 02:51.360
We also confirm the VLAN numbers.

76
02:51.360 --> 02:52.920
So it's VLAN 24 for site 2.

77
02:52.920 --> 02:53.880
Fantastic.

78
02:53.880 --> 02:56.000
And VLAN 23 for site 1.

79
02:56.000 --> 02:57.720
So we go ahead and collapse all those.

80
02:57.720 --> 03:00.600
And with these external segments, one at site 1 and one site 2
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

80
02:57.720 --> 03:00.600
And with these external segments, one at site 1 and one site 2

81
03:00.600 --> 03:03.440
created, we can then leverage those and use those

82
03:03.440 --> 03:05.680
when we start creating our Tier 0 gateway

83
03:05.680 --> 03:08.120
and connecting it to those external segments.

84
03:08.120 --> 03:10.320
And speaking of Tier 0 gateways, that's

85
03:10.320 --> 03:12.840
what we get to create in the very next video.

86
03:12.840 --> 03:15.640
So I'll see you there in just a moment.
