00:00:00,000 --> 00:00:03,776
[AUDIO LOGO]

2
00:00:03,776 --> 00:00:08,039

3
00:00:08,039 --> 00:00:11,250
So now that we've discussed some
of those details of Ethernet

4
00:00:11,250 --> 00:00:15,480
over MPLS, it's of course time
to jump into the command line

5
00:00:15,480 --> 00:00:17,470
and get this up and running.

6
00:00:17,470 --> 00:00:21,140
So as usual, we'll bring
up our topology first.

7
00:00:21,140 --> 00:00:23,640
We'll talk about which devices
we're going to be configuring

8
00:00:23,640 --> 00:00:25,140
and what we're going
to be building,

9
00:00:25,140 --> 00:00:28,110
and then we'll jump into the
command line and get this up

10
00:00:28,110 --> 00:00:32,590
and running for customer B.

11
00:00:32,590 --> 00:00:36,970
So for this demonstration,
we're still on MPLS topology 2.

12
00:00:36,970 --> 00:00:40,690
But this time, we're going to
be dealing with customer B.

13
00:00:40,690 --> 00:00:42,790
So what we're going
to do is we're going

14
00:00:42,790 --> 00:00:46,450
to extend this time VLAN 10--

15
00:00:46,450 --> 00:00:51,070
we're going to extend this
between router 7 and router 10,

16
00:00:51,070 --> 00:00:55,690
customer B's headquarters
and customer B's remote site.

17
00:00:55,690 --> 00:00:57,970
Now of course, that
means our configuration

18
00:00:57,970 --> 00:01:02,920
is mostly going to be on router
2 and, once again, on router 5,

19
00:01:02,920 --> 00:01:05,830
but this time,
interface gigabit 4.

20
00:01:05,830 --> 00:01:09,160
So just like we
did with VPLS, we

21
00:01:09,160 --> 00:01:12,350
are going to have the default
some configurations and such,

22
00:01:12,350 --> 00:01:16,420
but let's just go ahead and jump
in and get started on router 2,

23
00:01:16,420 --> 00:01:21,847
configuring our ethernet
over MPLS interfaces.

24
00:01:21,847 --> 00:01:23,680
So the first thing we're
going to want to do

25
00:01:23,680 --> 00:01:26,120
is default that interface.

26
00:01:26,120 --> 00:01:30,940
So this is going to
be interface gig 0000.

27
00:01:30,940 --> 00:01:33,040
We'll commit that change
just to make sure all

28
00:01:33,040 --> 00:01:37,210
of the configuration is
off the gig 0000 interface.

29
00:01:37,210 --> 00:01:41,620
Then we'll start creating
our VLAN 10 interface

30
00:01:41,620 --> 00:01:45,110
that we're going to use
for our l2 transport.

31
00:01:45,110 --> 00:01:49,270
So we're going to
say interface 0000,

32
00:01:49,270 --> 00:01:51,130
and we're going to
make a subinterface.

33
00:01:51,130 --> 00:01:53,320
So we're going to make this 10.

34
00:01:53,320 --> 00:01:56,710
Of course, the subinterface
doesn't have to match the VLAN,

35
00:01:56,710 --> 00:02:00,800
but once again it makes
sense for it to do so.

36
00:02:00,800 --> 00:02:03,340
And we're going to
specify that this

37
00:02:03,340 --> 00:02:06,290
is for a layer 2 transport.

38
00:02:06,290 --> 00:02:10,960
We're going to set this
for encapsulation dot1q

39
00:02:10,960 --> 00:02:12,910
for VLAN 10.

40
00:02:12,910 --> 00:02:15,070
Once again, of
course, this does have

41
00:02:15,070 --> 00:02:17,290
to match the VLAN
we want to extend.

42
00:02:17,290 --> 00:02:21,970
And we're also going to go
ahead and set the MTU to 1514

43
00:02:21,970 --> 00:02:25,090
to handle the extra
trunking encapsulation.

44
00:02:25,090 --> 00:02:28,630
We'll commit that change just
so the interface is ready.

45
00:02:28,630 --> 00:02:32,390
And then we're going
to configure our l2vpn.

46
00:02:32,390 --> 00:02:35,770
So here, we go into
l2vpn configuration,

47
00:02:35,770 --> 00:02:38,860
and we configure
this using xconnect.

48
00:02:38,860 --> 00:02:41,020
So we create an xconnect group.

49
00:02:41,020 --> 00:02:43,040
We can call this
whatever we want.

50
00:02:43,040 --> 00:02:46,390
Let's call it customer B VPN.

51
00:02:46,390 --> 00:02:51,610
Then, we're going to set the
P2P tag to 10 without the space,

52
00:02:51,610 --> 00:02:53,930
and then we'll assign
our interfaces.

53
00:02:53,930 --> 00:02:58,490
So we assign our subinterface
of gig 0, 0, 0, 0, dot 10.

54
00:02:58,490 --> 00:03:00,740
And then we configure
our remote neighbor.

55
00:03:00,740 --> 00:03:05,810
So this is going to be neighbor
IPv4, router 5's loopback.

56
00:03:05,810 --> 00:03:08,680
And then we set up
a pseudowire ID.

57
00:03:08,680 --> 00:03:12,980
Once again, we'll just use 10
since it's carrying VLAN 10.

58
00:03:12,980 --> 00:03:15,400
We'll commit those
changes, and then we

59
00:03:15,400 --> 00:03:18,700
should be able to exit
configuration here on router 2.

60
00:03:18,700 --> 00:03:22,800
So now, let's go over
and configure router 5.

61
00:03:22,800 --> 00:03:25,050
So router 5, of
course, on IOS XE

62
00:03:25,050 --> 00:03:26,860
is going to be a bit different.

63
00:03:26,860 --> 00:03:29,200
We still, however, want
to default our interface,

64
00:03:29,200 --> 00:03:31,650
so this is going
to be gigabit 4.

65
00:03:31,650 --> 00:03:34,650
Then we'll go into
interface gigabit 4.

66
00:03:34,650 --> 00:03:38,730
This is mostly going to be
the same way as we did VPLS.

67
00:03:38,730 --> 00:03:41,550
So we're going to set
up our service instance.

68
00:03:41,550 --> 00:03:44,610
This time, we'll do
service instance 10,

69
00:03:44,610 --> 00:03:48,270
keeping in step with everything
using the VLAN number.

70
00:03:48,270 --> 00:03:50,040
Again, it doesn't have to.

71
00:03:50,040 --> 00:03:53,130
What does have to
is, when we set up

72
00:03:53,130 --> 00:03:57,060
our encapsulation for
dot1q, this of course

73
00:03:57,060 --> 00:04:00,010
does have to be VLAN 10.

74
00:04:00,010 --> 00:04:01,800
Let's go ahead and
exit out of this,

75
00:04:01,800 --> 00:04:05,460
and we'll set up our
l2vpn connection now.

76
00:04:05,460 --> 00:04:08,640
So on IOS XE, we do l2vpn.

77
00:04:08,640 --> 00:04:12,910
And then, of course, there's
no sub configuration mode,

78
00:04:12,910 --> 00:04:17,160
so we go right to xconnect
and we set our context.

79
00:04:17,160 --> 00:04:19,720
Once again, this is
essentially just a name,

80
00:04:19,720 --> 00:04:24,510
so we'll call it tag 10
just like we did on IOS XR.

81
00:04:24,510 --> 00:04:26,850
Now, we get our sub
configuration mode

82
00:04:26,850 --> 00:04:28,500
for xconnect.

83
00:04:28,500 --> 00:04:30,760
Now, we set up our members.

84
00:04:30,760 --> 00:04:32,370
So we're going to
set up a member--

85
00:04:32,370 --> 00:04:34,740
is going to be a pseudowire.

86
00:04:34,740 --> 00:04:36,810
The pseudowire, we just
have to give it a number.

87
00:04:36,810 --> 00:04:38,850
Once again, we'll stick
with everything sort

88
00:04:38,850 --> 00:04:40,290
of being 10 here.

89
00:04:40,290 --> 00:04:42,100
We'll give it our
neighbor's address,

90
00:04:42,100 --> 00:04:44,730
which is going to be
router 2's loopback.

91
00:04:44,730 --> 00:04:48,900
We give it the identifier, and
then we set the encapsulation

92
00:04:48,900 --> 00:04:51,240
to run over MPLS.

93
00:04:51,240 --> 00:04:52,630
The other member
here, of course,

94
00:04:52,630 --> 00:04:54,610
is going to be the
gigabit interface.

95
00:04:54,610 --> 00:04:58,860
So it's going to be gigabit
4, service instance 10.

96
00:04:58,860 --> 00:05:01,200
We'll exit configuration.

97
00:05:01,200 --> 00:05:03,630
We see our targeted
LDP neighborship

98
00:05:03,630 --> 00:05:05,640
to router 2 come up.

99
00:05:05,640 --> 00:05:07,840
Let's go ahead and
do some verification.

100
00:05:07,840 --> 00:05:13,020
So we can do show
l2vpn xconnect.

101
00:05:13,020 --> 00:05:15,540
Actually, that's
the IOS XR command.

102
00:05:15,540 --> 00:05:18,780
Let's try the IOS
XE command instead.

103
00:05:18,780 --> 00:05:25,390
It's show l2vpn atom
vc, for virtual circuit.

104
00:05:25,390 --> 00:05:29,610
So here, we can see that we have
our pseudo wires up, connected

105
00:05:29,610 --> 00:05:32,460
between peer 1 and peer 2.

106
00:05:32,460 --> 00:05:33,960
We're, of course,
focusing right now

107
00:05:33,960 --> 00:05:37,710
on pseudowire 10
going to router 2.

108
00:05:37,710 --> 00:05:41,580
Pseudowire 100002 is from VPLS.

109
00:05:41,580 --> 00:05:45,390
So focusing on the pw10,
it is currently up.

110
00:05:45,390 --> 00:05:47,950
It is a point-to-point link.

111
00:05:47,950 --> 00:05:50,250
And we could get some
more details on that

112
00:05:50,250 --> 00:05:56,490
by adding VCID 10 and
detail to the end of this.

113
00:05:56,490 --> 00:05:59,490
So again, looking over
this, lots of information,

114
00:05:59,490 --> 00:06:02,610
but we see that it's
pseudowire 10, it's up.

115
00:06:02,610 --> 00:06:04,950
The vc status is up.

116
00:06:04,950 --> 00:06:07,710
Pseudowire type is ethernet.

117
00:06:07,710 --> 00:06:12,120
We see the destination address
is router 2's loopback.

118
00:06:12,120 --> 00:06:17,170
Our local egress
interface is gigabit 1.4.

119
00:06:17,170 --> 00:06:19,260
And it also shows us
the label that it's

120
00:06:19,260 --> 00:06:20,910
going to be using for this--

121
00:06:20,910 --> 00:06:24,720
24002 and 24009.

122
00:06:24,720 --> 00:06:28,650
We can also see down here
under the signaling protocol

123
00:06:28,650 --> 00:06:32,160
that, of course, the
peer 10.2.2.2 is up,

124
00:06:32,160 --> 00:06:34,950
but that it's a
targeted hello going

125
00:06:34,950 --> 00:06:39,432
from 10.5.5.5 to 10.2.2.2.

126
00:06:39,432 --> 00:06:42,630
As we can see, there's a
lot of information in here

127
00:06:42,630 --> 00:06:44,730
that you can look
over, including

128
00:06:44,730 --> 00:06:47,710
again local and remote labels
that are going to be used

129
00:06:47,710 --> 00:06:49,240
and so on.

130
00:06:49,240 --> 00:06:53,190
So let's go do our
verification on router 2 now.

131
00:06:53,190 --> 00:06:56,390
So now would probably be
a good time to do the show

132
00:06:56,390 --> 00:07:01,100
l2vpn xconnect, and it'll
work much better here

133
00:07:01,100 --> 00:07:03,260
than it did on IOS XE.

134
00:07:03,260 --> 00:07:05,600
So as you can see, this is
sort of the same as looking

135
00:07:05,600 --> 00:07:08,960
at the atom virtual circuit
that we looked at on IOS XE.

136
00:07:08,960 --> 00:07:12,560
But again, we see that this
is part of the xconnect group

137
00:07:12,560 --> 00:07:14,600
customer B VPN.

138
00:07:14,600 --> 00:07:16,550
Its name is tag 10.

139
00:07:16,550 --> 00:07:20,900
Its current status is
up, and segment one

140
00:07:20,900 --> 00:07:25,910
is going out our local gigabit
0, 0, 0, 0, dot 10 interface,

141
00:07:25,910 --> 00:07:28,940
and segment two going
to the remote side

142
00:07:28,940 --> 00:07:33,390
is going to 10.5.5.5.

143
00:07:33,390 --> 00:07:38,865
We can also add to this and
say interface gig 0, 0, 0,

144
00:07:38,865 --> 00:07:43,110
0, dot 10, detail,
and this will tell us

145
00:07:43,110 --> 00:07:46,620
that this is a member of
the group customer B VPN.

146
00:07:46,620 --> 00:07:48,930
We see the xconnect tag.

147
00:07:48,930 --> 00:07:50,760
The state is currently up.

148
00:07:50,760 --> 00:07:52,380
And of course, we
see the attachment

149
00:07:52,380 --> 00:07:57,900
circuit is in fact the gigabyte
0, 0, 0, 0 dot 10, and it's up.

150
00:07:57,900 --> 00:07:59,460
We see that it's a VLAN.

151
00:07:59,460 --> 00:08:03,420
It's not rewriting tags,
so the VLAN range here

152
00:08:03,420 --> 00:08:08,730
is going to be-- well, 10 to
10, so essentially just 10.

153
00:08:08,730 --> 00:08:10,590
We also see that
for the pseudowire,

154
00:08:10,590 --> 00:08:13,131
the neighbor is 10.5.5.5.

155
00:08:13,131 --> 00:08:16,650
The pseudowire ID is 10.

156
00:08:16,650 --> 00:08:18,780
And of course, the
encapsulation is

157
00:08:18,780 --> 00:08:21,930
MPLS using LDP as the protocol.

158
00:08:21,930 --> 00:08:25,680
Once again, a lot more
information here, but we

159
00:08:25,680 --> 00:08:28,990
can get a lot of good stuff
out of these commands.

160
00:08:28,990 --> 00:08:31,140
So now that it looks like
everything's working,

161
00:08:31,140 --> 00:08:34,169
let's go ahead and
verify our clients.

162
00:08:34,169 --> 00:08:37,860
Let's jump over to router 7.

163
00:08:37,860 --> 00:08:41,590
On router 7, we're simply going
to create a VLAN 10 interface.

164
00:08:41,590 --> 00:08:44,460
So this will be gigabit 1.10.

165
00:08:44,460 --> 00:08:47,920
Encapsulation is going
to follow VLAN 10.

166
00:08:47,920 --> 00:08:52,980
And we'll give it an IP
address of 192.168.10.7,

167
00:08:52,980 --> 00:08:57,810
again representing
VLAN 10 and host ID 7.

168
00:08:57,810 --> 00:09:00,270
And we'll make that a slash 24.

169
00:09:00,270 --> 00:09:04,060
While we're here, let's just go
ahead and set up OSPF as well.

170
00:09:04,060 --> 00:09:06,510
We'll go ahead and
set the router ID,

171
00:09:06,510 --> 00:09:11,340
and we'll just bring in all
the interfaces into area 0.

172
00:09:11,340 --> 00:09:13,980
Now, let's go
configure router 10.

173
00:09:13,980 --> 00:09:16,200
We've done a few of
these now, so we'll just

174
00:09:16,200 --> 00:09:18,930
paste the configuration
in here on router 10.

175
00:09:18,930 --> 00:09:22,260
Once again, we're simply
creating a subinterface,

176
00:09:22,260 --> 00:09:24,930
giving it the IP
address, and setting up

177
00:09:24,930 --> 00:09:27,250
OSPF on the interface.

178
00:09:27,250 --> 00:09:30,660
So we see here that
OSPF does come up

179
00:09:30,660 --> 00:09:34,110
with router 7, which means we
should have a couple of things

180
00:09:34,110 --> 00:09:34,890
we can look at.

181
00:09:34,890 --> 00:09:37,800
First, we should, of course, be
able to ping the other side--

182
00:09:37,800 --> 00:09:41,040
192.168.10.7.

183
00:09:41,040 --> 00:09:43,440
We can see that
that's successful.

184
00:09:43,440 --> 00:09:46,680
If we do a show
IP route OSPF, we

185
00:09:46,680 --> 00:09:48,210
do see that we have
a network that's

186
00:09:48,210 --> 00:09:49,750
reachable on the other side.

187
00:09:49,750 --> 00:09:52,000
Let's go ahead and
trace to that this time.

188
00:09:52,000 --> 00:09:55,470
So let's go to 10.100.1.7.

189
00:09:55,470 --> 00:09:58,500
And we can see that
just like our VPLS,

190
00:09:58,500 --> 00:10:00,540
this appears to
be going directly,

191
00:10:00,540 --> 00:10:03,000
and we don't see any of
the devices in the middle

192
00:10:03,000 --> 00:10:05,220
because they're all
being encapsulated

193
00:10:05,220 --> 00:10:09,650
in our ethernet
over MPLS tunnel.

194
00:10:09,650 --> 00:10:12,530
In this video, we
took a look at how

195
00:10:12,530 --> 00:10:16,160
to set up a point-to-point
connection using Ethernet

196
00:10:16,160 --> 00:10:20,060
over MPLS for our
customer B client

197
00:10:20,060 --> 00:10:23,180
going between routers 7 and 10.

198
00:10:23,180 --> 00:10:28,310
We also saw how, just like
VPLS, once this is done,

199
00:10:28,310 --> 00:10:31,850
we don't see any of the devices
in the middle when we're

200
00:10:31,850 --> 00:10:34,040
doing things like tracing.

201
00:10:34,040 --> 00:10:37,280
It's because it's a
direct layer 2 connection.

202
00:10:37,280 --> 00:10:39,920
So that pretty much
covers everything

203
00:10:39,920 --> 00:10:42,500
that we need to
discuss in this skill.

204
00:10:42,500 --> 00:10:46,910
That leaves us with just a
review in the form of a quiz,

205
00:10:46,910 --> 00:10:49,770
and that's exactly what
we're going to do next.

206
00:10:49,770 --> 00:10:53,120
Until then, I hope this has
been informative for you,

207
00:10:53,120 --> 00:10:56,230
and I'd like to thank
you for viewing.

208
00:10:56,230 --> 00:11:00,000
