WEBVTT

1
00:00.000 --> 00:03.560
So at this part of our journey, we're going to go and create the tier one

2
00:03.560 --> 00:04.640
stretch gateway

3
00:04.640 --> 00:07.200
and make it available to both site one and site two.

4
00:07.200 --> 00:08.800
We'll link it to the tier zero gateway.

5
00:08.800 --> 00:12.480
We'll also tell the tier one gateway that we wanted to share any of its

6
00:12.480 --> 00:13.240
directly connected

7
00:13.240 --> 00:16.750
networks like the segment 10 that we'll be adding to make sure we share that up

8
00:16.750 --> 00:16.920
to the

9
00:16.920 --> 00:18.440
tier zero as well.

10
00:18.440 --> 00:22.360
And then we'll create segment 10 and associate it with the tier one gateway.

11
00:22.360 --> 00:25.160
And we'll use the IP dressing space of 10, 10, 0, 0.

12
00:25.160 --> 00:29.840
And we'll give the tier one gateway the address of dot one on that segment.

13
00:29.840 --> 00:31.920
So once again, we'll head up to the global manager.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

13
00:29.840 --> 00:31.920
So once again, we'll head up to the global manager.

14
00:31.920 --> 00:35.640
We'll let our tier one gateway and connect the segment to it.

15
00:35.640 --> 00:39.530
So back at the global manager, verifying we're on the right device, we are

16
00:39.530 --> 00:40.480
fantastic.

17
00:40.480 --> 00:44.890
And with the networking tab selected on the left hand side, we'll go down to

18
00:44.890 --> 00:45.720
tier one

19
00:45.720 --> 00:46.720
gateways.

20
00:46.720 --> 00:49.120
So currently we have no tier one gateways anywhere.

21
00:49.120 --> 00:51.640
So we'll click on add tier one gateway.

22
00:51.640 --> 00:55.880
Let's call the stretched tier one and we'll use active standby.

23
00:55.880 --> 00:59.290
And then we'll associate this tier one gateway with our tier zero right above

24
00:59.290 --> 01:00.000
it, which is
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

25
01:00.000 --> 01:01.680
the tier zero we created earlier.

26
01:01.680 --> 01:03.120
So we'll associate it there.

27
01:03.120 --> 01:07.200
And then I'm also going to set this up to be preemptive like I did on the tier

28
01:07.200 --> 01:07.280
zero.

29
01:07.280 --> 01:08.680
And then we scroll down.

30
01:08.680 --> 01:13.470
It's already presuming that because site one and site two are already

31
01:13.470 --> 01:14.440
associated with

32
01:14.440 --> 01:17.860
and able to use the tier zero gateway, this tier one gateway that we just

33
01:17.860 --> 01:18.640
connected that

34
01:18.640 --> 01:21.960
tier zero gateway, it also assumes we want to available at both sites.

35
01:21.960 --> 01:25.970
But we could click on a little trash can here and remove it from one or both

36
01:25.970 --> 01:26.600
sites.

37
01:26.600 --> 01:30.600
We don't have to have this new T one gateway available at both sites.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

37
01:26.600 --> 01:30.600
We don't have to have this new T one gateway available at both sites.

38
01:30.600 --> 01:32.960
So because we do want it, we'll leave that in place.

39
01:32.960 --> 01:36.490
Now we also get to choose who gets to be the primary and who gets to be the

40
01:36.490 --> 01:37.480
secondary site

41
01:37.480 --> 01:38.640
one or site two.

42
01:38.640 --> 01:43.460
So to make this consistent with the actual T zero, let me go ahead and set the

43
01:43.460 --> 01:44.240
site one

44
01:44.240 --> 01:47.640
as the primary and set site two as the secondary.

45
01:47.640 --> 01:50.580
And then if you have multiple edge cluster nodes, you can select the one you

46
01:50.580 --> 01:51.480
want to use.

47
01:51.480 --> 01:54.440
So at each site, I only have one edge cluster.

48
01:54.440 --> 01:58.110
So I'll choose that edge cluster for site two and I'll use the respective edge

49
01:58.110 --> 01:58.640
cluster

50
01:58.640 --> 02:02.240
at site one and it'll automatically allocate the edges for that.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

50
01:58.640 --> 02:02.240
at site one and it'll automatically allocate the edges for that.

51
02:02.240 --> 02:06.760
So if you want to specify specific edge nodes within a cluster to go ahead and

52
02:06.760 --> 02:07.440
use, you

53
02:07.440 --> 02:08.920
can go ahead and specify it.

54
02:08.920 --> 02:12.220
So I'm going to say go ahead and auto allocate the edges and then also under

55
02:12.220 --> 02:13.240
route advertisement

56
02:13.240 --> 02:17.900
right here, which simply says, please Mr tier one gateway, please advertise up

57
02:17.900 --> 02:18.240
to your

58
02:18.240 --> 02:22.080
tier zero, any directly connected segments that may come along.

59
02:22.080 --> 02:26.190
So when we start adding segments like the 10 10 network and the 10 20 network,

60
02:26.190 --> 02:26.360
that

61
02:26.360 --> 02:29.890
routing information can be advertised up to the tier zero gateway, which is a

62
02:29.890 --> 02:30.760
good idea.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

62
02:29.890 --> 02:30.760
good idea.

63
02:30.760 --> 02:32.880
So we'll go ahead and set that as well.

64
02:32.880 --> 02:34.420
And let's click on save.

65
02:34.420 --> 02:38.880
So let's click on yes to continue editing and we could further set up the D HCP

66
02:38.880 --> 02:38.880
.

67
02:38.880 --> 02:42.440
However, there's a few additional steps that we need for the D HCP services

68
02:42.440 --> 02:42.680
with D H P

69
02:42.680 --> 02:46.280
relay, including sitting up an additional external interface up at the tier

70
02:46.280 --> 02:46.720
zero.

71
02:46.720 --> 02:48.320
So we'll do that in a separate step.

72
02:48.320 --> 02:50.120
So let me just check our work real quick.

73
02:50.120 --> 02:54.390
So we got site one site to site one primary site to secondary that all looks

74
02:54.390 --> 02:54.960
good.

75
02:54.960 --> 02:56.680
So we'll go ahead and click on close there.

76
02:56.680 --> 02:59.930
And just for a moment, I'm going to go back up to the tier zero gateways and

77
02:59.930 --> 03:01.120
just to confirm
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

77
02:59.930 --> 03:01.120
just to confirm

78
03:01.120 --> 03:04.200
to see which of our two sites is going to be the primary.

79
03:04.200 --> 03:06.800
So I'll click on edit and scroll down.

80
03:06.800 --> 03:11.090
And so for the tier zero gateway as well site one is primary and site two is

81
03:11.090 --> 03:12.040
secondary.

82
03:12.040 --> 03:13.640
So I'll go ahead and close that.

83
03:13.640 --> 03:17.040
And our last piece here was to go ahead and create a segment.

84
03:17.040 --> 03:21.010
So we'll click on segments again here at the NSX global manager and we'll click

85
03:21.010 --> 03:21.480
on add

86
03:21.480 --> 03:22.480
segment.

87
03:22.480 --> 03:25.550
Let's go ahead and call this stretched sag 10 and we'll go ahead and connect

88
03:25.550 --> 03:25.920
this to

89
03:25.920 --> 03:29.320
our tier one gateway right there from the drop down.

90
03:29.320 --> 03:34.040
And then we'll give the logical interface address for the segment of 10 dot 10
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

90
03:29.320 --> 03:34.040
And then we'll give the logical interface address for the segment of 10 dot 10

91
03:34.040 --> 03:34.600
dot zero

92
03:34.600 --> 03:39.270
dot one with a 24 bit mask and for our two sites, it took the overlay transport

93
03:39.270 --> 03:39.640
zone that

94
03:39.640 --> 03:43.940
was identified as the default transport zone and this new segment, which is

95
03:43.940 --> 03:44.680
connected to

96
03:44.680 --> 03:47.880
the tier one gateway, which is being used by both sites.

97
03:47.880 --> 03:51.020
This new segment is going to be associated with those respective transport

98
03:51.020 --> 03:51.480
zones.

99
03:51.480 --> 03:53.840
So we'll scroll down and that looks good.

100
03:53.840 --> 03:56.480
So we'll click on save and then click on no.

101
03:56.480 --> 04:01.070
So now if we were to pop over to the local manager at site one or site two, we
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

101
03:56.480 --> 04:01.070
So now if we were to pop over to the local manager at site one or site two, we

102
04:01.070 --> 04:01.400
can get

103
04:01.400 --> 04:03.560
a nice beautiful picture of the topologies.

104
04:03.560 --> 04:05.320
Let's jump over to site two.

105
04:05.320 --> 04:08.520
So from global manager, we use the drop down to site two.

106
04:08.520 --> 04:12.450
Let's go to the networking tab here at the local manager at site two and click

107
04:12.450 --> 04:13.080
on network

108
04:13.080 --> 04:14.000
topology.

109
04:14.000 --> 04:16.440
So from site two's perspective, here is the topology.

110
04:16.440 --> 04:20.800
We have our two external interfaces 24, one, two, sixty one and sixty two.

111
04:20.800 --> 04:23.440
We have our stretch tier zero gateway.

112
04:23.440 --> 04:27.530
If we scroll down, then we have our tier one gateway and that's connected to

113
04:27.530 --> 04:28.240
this segment

114
04:28.240 --> 04:29.520
right here, 10, 10, zero.

115
04:29.520 --> 04:34.070
Now before we start attaching clients here at site one or site two to this
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

115
04:29.520 --> 04:34.070
Now before we start attaching clients here at site one or site two to this

116
04:34.070 --> 04:35.040
stretch segment

117
04:35.040 --> 04:38.000
10, I also want to set up DHCP services.

118
04:38.000 --> 04:41.970
So join me in the next video as we implement DHCP services in our NSX

119
04:41.970 --> 04:42.840
federation.
