1
00:00.000 --> 00:02.500
So for our game plan, let's do some clean up.

2
00:02.500 --> 00:04.600
And for the cleanup, we're going to do all of our work

3
00:04.600 --> 00:07.800
by being logged in directly here at the Global Manager.

4
00:07.800 --> 00:09.000
And then from the Global Manager,

5
00:09.000 --> 00:10.700
if we ever needed to jump over to the configuration here,

6
00:10.700 --> 00:12.500
the Local Manager for Site 1,

7
00:12.500 --> 00:14.100
or the Local Manager for Site 2,

8
00:14.100 --> 00:17.100
we can do that right here from the interface at the Global Manager.

9
00:17.100 --> 00:20.300
And again, this will be picking up from where we left off the topology

10
00:20.300 --> 00:24.200
in the previous skill where we implemented the NSX Federation to begin with.

11
00:24.200 --> 00:26.900
So with that being said, let's head over to the Global Manager.

12
00:26.900 --> 00:30.900
So here at the Global NSX Manager up at the top right here,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

12
00:26.900 --> 00:30.900
So here at the Global NSX Manager up at the top right here,

13
00:30.900 --> 00:32.600
we can go ahead and use the dropdown.

14
00:32.600 --> 00:35.200
If we ever needed to jump over to Site 1 or Site 2,

15
00:35.200 --> 00:37.400
we can do that right here from the Global Manager.

16
00:37.400 --> 00:40.900
So currently, we have the NSX Global Manager selected.

17
00:40.900 --> 00:42.900
And if we click here on System,

18
00:42.900 --> 00:46.200
that can confirm for us, the details for our Global Manager,

19
00:46.200 --> 00:48.100
also confirm for us right here,

20
00:48.100 --> 00:51.800
that Site 1 is good to go, and also Site 2 as well,

21
00:51.800 --> 00:53.700
including the remote tunnel endpoints.

22
00:53.700 --> 00:55.500
And if we click here on Location Manager,

23
00:55.500 --> 00:57.200
that also confirms those details

24
00:57.200 --> 00:59.500
where we have the NSX Global Manager right here,

25
00:59.500 --> 01:02.100
and then below it, Site 1 and Site 2,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

25
00:59.500 --> 01:02.100
and then below it, Site 1 and Site 2,

26
01:02.100 --> 01:03.600
and everything looks good to go.

27
01:03.600 --> 01:05.700
All right, so from the Global Manager,

28
01:05.700 --> 01:08.200
if we click on the Networking tab up here at the top,

29
01:08.200 --> 01:10.000
it defaults to Network Overview,

30
01:10.000 --> 01:12.200
and we have two Tier 0 gateways,

31
01:12.200 --> 01:13.500
five Tier 1 gateways,

32
01:13.500 --> 01:15.900
and seven segments and two net rules.

33
01:15.900 --> 01:17.900
And because many of these have interdependencies,

34
01:17.900 --> 01:20.500
for example, the Tier 1s are connected to the Tier 0,

35
01:20.500 --> 01:22.500
and segments are connected to Tier 1s,

36
01:22.500 --> 01:24.300
if we want to remove some of the config,

37
01:24.300 --> 01:26.300
we need to start here at these segments.

38
01:26.300 --> 01:27.800
So here are all the segments.

39
01:27.800 --> 01:30.300
So this is the stretch segment that we have stretched across,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

39
01:27.800 --> 01:30.300
So this is the stretch segment that we have stretched across,

40
01:30.300 --> 01:34.300
Site 1 and Site 2, and all the other segments were imported

41
01:34.300 --> 01:36.500
when we onboarded Site 1 and Site 2.

42
01:36.500 --> 01:39.000
Also, I'm looking over here at the ports and interfaces,

43
01:39.000 --> 01:42.000
and almost all of these have at least one VM connected.

44
01:42.000 --> 01:43.800
So before we can delete the segment,

45
01:43.800 --> 01:46.000
we need to go to the VCR client

46
01:46.000 --> 01:48.300
and move the VMs off of those segments

47
01:48.300 --> 01:49.500
before it'll let us delete them.

48
01:49.500 --> 01:52.100
For example, it's right here, Site 2 Lab 2, Site 30,

49
01:52.100 --> 01:54.500
if we try to delete that by clicking on the three dots,

50
01:54.500 --> 01:57.200
and then clicking on delete, and then clicking on delete,

51
01:57.200 --> 01:59.700
it says, "Wah, wah, wah, can't delete it."

52
01:59.700 --> 02:02.200
So let's head over to the VCR client in charge of Site 1,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

52
01:59.700 --> 02:02.200
So let's head over to the VCR client in charge of Site 1,

53
02:02.200 --> 02:04.400
and also to the VCR client in charge of Site 2,

54
02:04.400 --> 02:06.800
and let's move all the VMs at both sites

55
02:06.800 --> 02:09.100
off of any existing NSX segments

56
02:09.100 --> 02:10.900
so that we can go ahead and delete them.

57
02:10.900 --> 02:12.100
So here in the VCR client,

58
02:12.100 --> 02:15.200
and this is for Site 1 that we're dealing with right here,

59
02:15.200 --> 02:17.100
let's click on the networking tab,

60
02:17.100 --> 02:19.200
and let's go down to our NSX segments,

61
02:19.200 --> 02:21.200
and we have a couple there.

62
02:21.200 --> 02:24.000
So fast way to move these is to right click on the network segment,

63
02:24.000 --> 02:26.400
and then from the menu click right here on Migrate VMs

64
02:26.400 --> 02:28.600
to another network, and I'm going to park them all

65
02:28.600 --> 02:31.000
on my Management Pork Group temporarily
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

65
02:28.600 --> 02:31.000
on my Management Pork Group temporarily

66
02:31.000 --> 02:32.900
until we move them to a new stretch segment

67
02:32.900 --> 02:35.200
we create as part of this set of videos.

68
02:35.200 --> 02:37.600
So we'll click on Next, and I'll select all those VMs

69
02:37.600 --> 02:38.900
that are currently on that segment,

70
02:38.900 --> 02:41.100
and migrate all of them with just a couple clicks,

71
02:41.100 --> 02:43.900
and they should disappear here in just a moment

72
02:43.900 --> 02:45.600
because they are being moved over

73
02:45.600 --> 02:47.200
to the Lab Management Pork Group.

74
02:47.200 --> 02:50.400
Fantastic, so here is another NSX segment,

75
02:50.400 --> 02:53.000
and Mint A is on segment 10, so we'll right click,

76
02:53.000 --> 02:55.300
and from the dropdown click on Migrate VMs

77
02:55.300 --> 02:58.400
to another network, and then we'll go ahead and choose a target,

78
02:58.400 --> 03:00.500
I'll put it on my Pork Group for the Management Network,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

78
02:58.400 --> 03:00.500
I'll put it on my Pork Group for the Management Network,

79
03:00.500 --> 03:03.000
click on Next, I'll go ahead and select Mint A,

80
03:03.000 --> 03:06.200
click on Next, and Finish, and that's being moved,

81
03:06.200 --> 03:09.500
and then on our external segment, no VMs there,

82
03:09.500 --> 03:11.500
and for Seg 50 stretched, we have one there,

83
03:11.500 --> 03:14.400
so we'll right click and Migrate VMs to another network,

84
03:14.400 --> 03:16.900
and choose my Management Pork Group, click on Next,

85
03:16.900 --> 03:19.200
then I'll select that VM, click on Next,

86
03:19.200 --> 03:22.300
and Finish, and now we should have at Site A,

87
03:22.300 --> 03:26.300
no more VMs on any of the NSX segments that looks good,

88
03:26.300 --> 03:30.100
so let's head over to the vCenter that's managing Site 2.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

88
03:26.300 --> 03:30.100
so let's head over to the vCenter that's managing Site 2.

89
03:30.100 --> 03:32.900
So I put Site 2 here in dark mode, so it will stand out,

90
03:32.900 --> 03:37.100
so this is vcsa-2.ogit.lab,

91
03:37.100 --> 03:39.400
and let's go to the Networking tab here,

92
03:39.400 --> 03:40.800
and let's go down to our NSX segments,

93
03:40.800 --> 03:42.100
the ones here with the ends,

94
03:42.100 --> 03:44.400
and we have nobody on that one,

95
03:44.400 --> 03:47.200
and we have one here, so I'll right click on that segment,

96
03:47.200 --> 03:50.400
and then from the dropdown, choose Migrate VMs to another network,

97
03:50.400 --> 03:52.900
I'll park that over on the Lab 2 Management Pork Group,

98
03:52.900 --> 03:55.200
click on Next, and select all the VMs there,

99
03:55.200 --> 03:58.300
all that one, I'll select that VM there, Lab 2 Tiny,

100
03:58.300 --> 04:01.400
click on Next, and Finish, and that should move,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

100
03:58.300 --> 04:01.400
click on Next, and Finish, and that should move,

101
04:01.400 --> 04:06.100
so that is Survey Says, that is now gone, fantastic,

102
04:06.100 --> 04:10.000
and Seg 50 has one as well, so we'll right click and Migrate,

103
04:10.000 --> 04:12.800
and we'll park it over there on the Management Pork Group,

104
04:12.800 --> 04:15.800
and select that VM as well, click on Next, and Finish,

105
04:15.800 --> 04:18.900
and that'll be moved as well, so just to confirm,

106
04:18.900 --> 04:23.500
we have no VMs connected to any of these overlay segments,

107
04:23.500 --> 04:27.200
fantastic, so let's go back to the NSX Global Manager,

108
04:27.200 --> 04:29.700
so back at the Global Manager, if we do a refresh,

109
04:29.700 --> 04:32.100
so let's take all the overlay segments that no longer
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

109
04:29.700 --> 04:32.100
so let's take all the overlay segments that no longer

110
04:32.100 --> 04:34.000
have those VMs attached and we'll delete them,

111
04:34.000 --> 04:37.400
so we'll click on the three dots, delete and delete,

112
04:37.400 --> 04:39.800
and let's go to the next one, which is right here,

113
04:39.800 --> 04:42.600
Site 1, Site 10, click on the three dots,

114
04:42.600 --> 04:45.700
click on Delete and Delete, fantastic,

115
04:45.700 --> 04:49.800
let's next go to Site 1, Site 20, click on Edit,

116
04:49.800 --> 04:53.000
click on the three dots, click on Delete and Delete,

117
04:53.000 --> 04:54.500
and then we'll go down to this one right here,

118
04:54.500 --> 04:57.800
which is Site 2 Lab 2, Site 30, delete that segment,

119
04:57.800 --> 05:00.800
delete, and let's also go down to this one right here,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

119
04:57.800 --> 05:00.800
delete, and let's also go down to this one right here,

120
05:00.800 --> 05:04.700
and Delete and Delete, and click on Refresh,

121
05:04.700 --> 05:07.200
and that looks great, now these two external segments,

122
05:07.200 --> 05:10.400
ones for VLAN 23, and the other ones for VLAN 24

123
05:10.400 --> 05:12.300
for Site 1 and Site 2, respectively,

124
05:12.300 --> 05:15.300
those have some encumbrances, because we have the Tier 0

125
05:15.300 --> 05:16.700
gateways at each of those sites,

126
05:16.700 --> 05:19.900
which are currently using those external segments,

127
05:19.900 --> 05:21.400
sure enough right here, so as you can't delete this

128
05:21.400 --> 05:22.800
being referenced by another object,

129
05:22.800 --> 05:25.200
and that is the Tier 0 interface,

130
05:25.200 --> 05:26.500
let's go to our Tier 0 gateway,

131
05:26.500 --> 05:28.900
and if we try to delete the Tier 0 gateway,

132
05:28.900 --> 05:31.560
it's also gonna complain because we have our Tier 1
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

132
05:28.900 --> 05:31.560
it's also gonna complain because we have our Tier 1

133
05:31.560 --> 05:33.800
gateways attached to it, so let's do these in order,

134
05:33.800 --> 05:35.400
we'll go to our Tier 1 gateways,

135
05:35.400 --> 05:37.800
and let's go ahead and delete those first,

136
05:37.800 --> 05:39.700
so we'll delete all the Tier 1 gateways,

137
05:39.700 --> 05:42.400
so let's just go through that step by step,

138
05:42.400 --> 05:44.200
clicking on the three dots for each of them,

139
05:44.200 --> 05:47.900
delete and delete and delete and delete.

140
05:47.900 --> 05:49.200
Including our T1 stretched,

141
05:49.200 --> 05:51.000
we created in the previous set of videos,

142
05:51.000 --> 05:52.500
sold to delete that as well,

143
05:52.500 --> 05:54.900
and we'll do a refresh and boom,

144
05:54.900 --> 05:57.000
we have no more Tier 1 gateways,

145
05:57.000 --> 05:59.300
so if we go to our Tier 0 gateways now,

146
05:59.300 --> 06:01.400
we might have a better chance of deleting them,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

146
05:59.300 --> 06:01.400
we might have a better chance of deleting them,

147
06:01.400 --> 06:02.900
so we'll go ahead and take the first one there,

148
06:02.900 --> 06:04.800
and delete and delete,

149
06:04.800 --> 06:06.000
oh, we still have our reference,

150
06:06.000 --> 06:08.600
and it says .62 can't be deleted,

151
06:08.600 --> 06:09.800
dah, dah, dah, dah,

152
06:09.800 --> 06:12.400
oh, it's the virtual IP address that we have associated

153
06:12.400 --> 06:14.100
with those gateways, so let's edit.

154
06:14.100 --> 06:15.700
The Tier 0 gateways,

155
06:15.700 --> 06:17.200
so we'll click on edit,

156
06:17.200 --> 06:18.500
and the problem is right here,

157
06:18.500 --> 06:20.600
on the HA virtual IP address,

158
06:20.600 --> 06:24.100
currently it's leveraging for that HA virtual IP address,

159
06:24.100 --> 06:25.600
it's leveraging our edges,

160
06:25.600 --> 06:26.800
there's Edge 1 and Edge 2,

161
06:26.800 --> 06:29.600
so let's go ahead and delete the VIP information here,

162
06:29.600 --> 06:31.600
associated with the Tier 0 gateway,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

162
06:29.600 --> 06:31.600
associated with the Tier 0 gateway,

163
06:31.600 --> 06:32.600
click on apply,

164
06:32.600 --> 06:34.100
and now that's deleted,

165
06:34.100 --> 06:35.500
we'll go ahead and click on save,

166
06:35.500 --> 06:37.000
and close editing,

167
06:37.000 --> 06:38.800
and let's see if we can now delete it,

168
06:38.800 --> 06:41.000
so we'll click on delete for the gateway,

169
06:41.000 --> 06:44.400
delete, and survey says no problem,

170
06:44.400 --> 06:46.200
fantastic, so let's refresh here,

171
06:46.200 --> 06:48.700
and let's do the same thing for the site to gateway 0,

172
06:48.700 --> 06:50.300
we'll go in and edit it first,

173
06:50.300 --> 06:52.000
to remove the virtual IP address,

174
06:52.000 --> 06:53.500
it's using the edges,

175
06:53.500 --> 06:56.200
so we'll delete that virtual IP information,

176
06:56.200 --> 06:57.100
save that,

177
06:57.100 --> 06:58.100
save that,

178
06:58.100 --> 06:59.300
close editing,

179
06:59.300 --> 07:01.400
and now that we're not referencing those Edge nodes,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

179
06:59.300 --> 07:01.400
and now that we're not referencing those Edge nodes,

180
07:01.400 --> 07:03.400
let's go ahead and click on the three dots,

181
07:03.400 --> 07:04.600
and click on delete,

182
07:04.600 --> 07:05.700
and click on delete,

183
07:05.700 --> 07:07.500
and yeah, it's gone,

184
07:07.500 --> 07:10.800
so we've just wiped out the entire topology,

185
07:10.800 --> 07:12.400
at all of our sites,

186
07:12.400 --> 07:13.800
so right here on the global manager,

187
07:13.800 --> 07:16.000
if we click on networking and network overview,

188
07:16.000 --> 07:18.600
it shows us we have no Tier 0 or Tier 1 gateways,

189
07:18.600 --> 07:20.300
oh, we have a couple segments still,

190
07:20.300 --> 07:22.800
and those would be our external segments,

191
07:22.800 --> 07:24.500
and we are going to need those,

192
07:24.500 --> 07:25.500
but we'll just recreate them,

193
07:25.500 --> 07:27.200
I want our nice fresh clean slate,

194
07:27.200 --> 07:29.700
so we'll delete each of those as well,

195
07:29.700 --> 07:31.900
and delete again,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

195
07:29.700 --> 07:31.900
and delete again,

196
07:31.900 --> 07:33.400
and click on refresh,

197
07:33.400 --> 07:35.300
and now if we go to network overview,

198
07:35.300 --> 07:39.600
we should have absolutely nothing as far as segments,

199
07:39.600 --> 07:40.900
or Tier 1 gateways,

200
07:40.900 --> 07:42.000
or Tier 0 gateways,

201
07:42.000 --> 07:45.000
and if we popped over to one of our local managers,

202
07:45.000 --> 07:47.800
and a fast way of doing that is right here from the dropdown,

203
07:47.800 --> 07:49.200
let's go to site 1,

204
07:49.200 --> 07:51.100
by clicking on site 1 from the dropdown,

205
07:51.100 --> 07:55.000
and that whisks us away through time and space to site 1,

206
07:55.000 --> 07:56.400
so that's showing us right here,

207
07:56.400 --> 07:58.400
that we're currently at site 1,

208
07:58.400 --> 08:01.900
so effectively we're connected to the site 1 local manager,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

208
07:58.400 --> 08:01.900
so effectively we're connected to the site 1 local manager,

209
08:01.900 --> 08:02.700
so from here,

210
08:02.700 --> 08:05.100
if we go to networking at site 1,

211
08:05.100 --> 08:06.800
and click on network topology,

212
08:06.800 --> 08:09.400
you'll notice that there is nothing here to display,

213
08:09.400 --> 08:11.000
because there's no Tier 0 gateways,

214
08:11.000 --> 08:12.200
no Tier 1 gateways,

215
08:12.200 --> 08:12.900
no segments,

216
08:12.900 --> 08:13.600
no nothing.

217
08:13.600 --> 08:16.400
Alright, so let's go back to the NSX global manager,

218
08:16.400 --> 08:17.900
there's a couple ways of doing that.

219
08:17.900 --> 08:20.000
We can click here on the NSX logo,

220
08:20.000 --> 08:21.600
that'll take us back to the global manager,

221
08:21.600 --> 08:24.000
or we could use the dropdown once again,

222
08:24.000 --> 08:25.000
and from the dropdown,

223
08:25.000 --> 08:26.600
choose the NSX global,

224
08:26.600 --> 08:28.400
and it'll take us back to the global manager,

225
08:28.400 --> 08:29.700
including a little message here,

226
08:29.700 --> 08:30.700
that's just happened.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

226
08:29.700 --> 08:30.700
that's just happened.

227
08:30.700 --> 08:32.100
So now as far as our game plan goes,

228
08:32.100 --> 08:33.800
we have cleaned up our existing topology,

229
08:33.800 --> 08:36.500
and that puts us into perfect striking position

230
08:36.500 --> 08:38.400
for implementing our new topology,

231
08:38.400 --> 08:41.460
and once again, we'll be doing that by logging directly into the global manager

232
08:41.460 --> 08:41.600
,

233
08:41.600 --> 08:42.300
and when needed,

234
08:42.300 --> 08:44.400
we can pop out to each of the local managers,

235
08:44.400 --> 08:46.300
but most of the configuration we can do

236
08:46.300 --> 08:48.300
directly here at the global manager,

237
08:48.300 --> 08:51.200
and we'll begin the configuration of our new topology

238
08:51.200 --> 08:52.700
in the very next video.

239
08:52.700 --> 08:54.900
So I'll see you there in just a moment.
