1
00:00:14,850 --> 00:00:21,570
Okay so let's start with the Rhonda Archer the moment on the router.
2
00:00:21,860 --> 00:00:25,070
No IP addresses are configured.
3
00:00:25,070 --> 00:00:31,550
So the first thing we need to do is go on to the gigabit 0 0 0 interface and no shut at
4
00:00:34,940 --> 00:00:40,100
and then we need to create sub interfaces.
5
00:00:40,100 --> 00:00:47,530
So notice I'm going to choose dot 1 as the sub interface for VLAN 1.
6
00:00:47,610 --> 00:00:56,830
I'm going to specify an encapsulation of DOT 1 q using VLAN 1 as the native villain the management villain
7
00:00:57,240 --> 00:01:02,480
is typically your on tag the villain which by default is villain 1.
8
00:01:03,260 --> 00:01:12,090
I can now configure the IP address of the router the lost IP address in subnet 10 1 1 0 slash 24 is
9
00:01:12,090 --> 00:01:24,210
10 dot 1 to 1 2 5 4 so do show run shows us the configuration of the first sub interface.
10
00:01:24,210 --> 00:01:29,100
We now need to configure the second sub interface which is VLAN 10.
11
00:01:29,130 --> 00:01:35,400
You don't have to use the same numbers as the villain number that just makes it easier.
12
00:01:35,670 --> 00:01:38,770
So I'm going to specify V Line 10.
13
00:01:38,790 --> 00:01:45,580
This is not the native v LAN IP addresses tendered 1 to 10 to 2 5 4.
14
00:01:47,790 --> 00:01:49,280
So again show run
15
00:01:52,250 --> 00:02:00,310
there is the configuration of airline 10 and then I need to create a third sub interface for v land
16
00:02:00,310 --> 00:02:10,360
20 encapsulation is going to be top 1 q V Line 20 IP address is gonna be 10 dot wonder 20 dot 2 5 4
17
00:02:10,780 --> 00:02:12,850
slash 24.
18
00:02:12,850 --> 00:02:23,560
So again there's the configuration of the physical interface reveal and one sub interface Vila in terms
19
00:02:23,560 --> 00:02:27,680
of interface VLAN 20 sub interface.
20
00:02:27,900 --> 00:02:36,840
The next thing we need to do is configure the switch so on the switch show IP interface brief no IP
21
00:02:36,840 --> 00:02:45,890
addresses are configured Vila and one is administratively down at the moment so Conti interface of Ilan
22
00:02:45,940 --> 00:02:59,020
one no shut IP address tendered one that 1 2 5 3 slash 24 we've been told to only configure an IP address
23
00:02:59,050 --> 00:03:09,070
in V Line 1 so let's confirm that the switch can paying the router it can but that's not entirely correct
24
00:03:09,130 --> 00:03:20,160
yet we still need to configure this interface as a drunk Port Vila and one will work because it's the
25
00:03:20,160 --> 00:03:29,520
native v LAN but other v lines will not work so switch port mode trunk we need to specify an encapsulation
26
00:03:30,200 --> 00:03:35,640
so switch port trunk encapsulation dot one key
27
00:03:38,470 --> 00:03:41,560
and now we can make the port a trunk port.
28
00:03:41,860 --> 00:03:44,200
So those two commands are required.
29
00:03:44,200 --> 00:03:47,540
Interface went down it's now come up again.
30
00:03:47,830 --> 00:03:50,500
So show run.
31
00:03:50,630 --> 00:03:52,160
They are the two commands and gigabit.
32
00:03:52,170 --> 00:03:55,510
1 0 1.
33
00:03:55,640 --> 00:04:01,810
Can we stop paying for the router at the moment it's not working but now it is.
34
00:04:01,810 --> 00:04:05,710
It just took a while to notice the pings have now succeeded.
35
00:04:05,740 --> 00:04:08,820
Packet traces showing green on the link.
36
00:04:09,520 --> 00:04:11,710
So that looks good.
37
00:04:11,710 --> 00:04:17,520
We now need to configure VLAN 10 and VLAN 20.
38
00:04:17,860 --> 00:04:22,390
And we need to put our pieces into those villains.
39
00:04:22,780 --> 00:04:31,800
So our two pieces are connected to ports 1 0 2 and 1 0 3.
40
00:04:31,930 --> 00:04:33,560
So interface gigabit.
41
00:04:33,730 --> 00:04:41,900
1 0 2 switch port mode access switch port access VLAN 10.
42
00:04:41,920 --> 00:04:44,160
In this case interface gigabit.
43
00:04:44,170 --> 00:04:55,060
1 0 3 switch port mode access because it's a P.C. switch port access VLAN 20 so show run.
44
00:04:55,060 --> 00:05:09,000
What have we configured gigabit 1 0 1 is a trunk port gigabit 1 0 2 and 1 0 3 or access ports 1 0 2
45
00:05:09,000 --> 00:05:19,200
is in VLAN 10 1 0 3 is in V land 20 so we can use commands such as Show interface gigabit 1 0 1 switch
46
00:05:19,200 --> 00:05:23,930
port to verify the configuration of an interface.
47
00:05:24,270 --> 00:05:27,690
So this command shows us that gigabit.
48
00:05:27,690 --> 00:05:34,330
1 0 1 is configured as a trunk port and is operating as a trunk port.
49
00:05:34,410 --> 00:05:44,680
The encapsulation used is not one Q access v LAN is v lan 1 if we look at Interface gigabit.
50
00:05:44,680 --> 00:05:59,660
1 0 2 to this port is an access port in VLAN 10 look at 1 0 3 this port is an access port in VLAN 20
51
00:06:00,510 --> 00:06:01,870
so that looks good.
52
00:06:03,790 --> 00:06:09,450
We've configured the V lands on the switch we've configured the link between the rod and switch.
53
00:06:09,460 --> 00:06:12,790
Now we need to confirm that the pieces can ping each other.
54
00:06:12,950 --> 00:06:20,800
So on PCI 1 we've been told to configure the PSC with a static IP address the default gateway will be
55
00:06:20,800 --> 00:06:31,690
the router on the P.C. so I'll set both the default gateway and DNS to the router the IP address will
56
00:06:31,690 --> 00:06:41,350
be tendered one dot tendered one subnet mask is going to be a slash 24 subnet mask so on the command
57
00:06:41,380 --> 00:06:49,990
prompt IP config we can see the configuration of the P.C. that's correct.
58
00:06:49,990 --> 00:06:56,380
Per our instructions default gateway is wrong I should make that ten.
59
00:06:56,380 --> 00:06:59,380
Always good to verify.
60
00:06:59,770 --> 00:07:01,160
So do that again.
61
00:07:01,240 --> 00:07:07,380
That looks better can we paying the default gateway.
62
00:07:07,510 --> 00:07:08,290
Yes we can.
63
00:07:08,350 --> 00:07:17,680
So that's good to something similar on P.C. to default gateway will be tendered one to twenty two to
64
00:07:17,680 --> 00:07:26,860
five for DNS server will be tendered one to twenty two five for IP address of the P.C. will be tendered
65
00:07:26,860 --> 00:07:35,820
one dot twenty two to subnet mask will be a slash 24 subnet mosque open up a command prompt IP config
66
00:07:37,270 --> 00:07:39,130
that looks good can we paying
67
00:07:41,770 --> 00:07:42,620
the router.
68
00:07:42,760 --> 00:07:44,260
Yes we can.
69
00:07:44,260 --> 00:07:45,280
Can we ping.
70
00:07:45,460 --> 00:07:49,090
P.S. 1 so paying tendered wonder tender 1.
71
00:07:49,240 --> 00:08:01,220
Yes we can CPC to is able to ping P.S. 1 and can P.S. 1 paying P.S. 2 Yes it can.
72
00:08:01,220 --> 00:08:09,350
So we've successfully configured this network with V lands and interval and routing using a router on
73
00:08:09,350 --> 00:08:11,190
a stick.
74
00:08:11,190 --> 00:08:15,110
So now let's do the extra work for credits.
75
00:08:15,210 --> 00:08:20,180
How do we get everyone to talk to everyone on the switch.
76
00:08:20,210 --> 00:08:24,500
We need to configure an IP default gateway
77
00:08:28,250 --> 00:08:37,290
pointing to the router in the same subnet as the switch to paying 10 1 1 2 5 4.
78
00:08:37,460 --> 00:08:38,090
That works.
79
00:08:38,090 --> 00:08:49,330
Can the switch ping the first P.S. after the moment it looks like it can't can it ping the second P.C..
80
00:08:49,420 --> 00:08:51,990
At the moment it looks like it can't.
81
00:08:52,120 --> 00:08:58,780
When you use IP default gateway you need to ensure that routing is disabled.
82
00:08:58,810 --> 00:09:01,400
In this example writing is enabled.
83
00:09:01,420 --> 00:09:08,560
So we going to say no IP routing because this is a layer to switch and not a layer 3 switch and that
84
00:09:08,650 --> 00:09:14,140
should allow us to ping the pieces which it does.
85
00:09:14,260 --> 00:09:15,880
So this is the lesson.
86
00:09:16,120 --> 00:09:24,790
If you have IP routing enabled you don't use the default gateway command.
87
00:09:24,790 --> 00:09:33,030
So as soon as I enable IP riding on the switch the IP default gateway command is ignored by the switch
88
00:09:33,420 --> 00:09:36,820
and the switch can't ping the pieces.
89
00:09:36,930 --> 00:09:42,870
Now typically on switches the default behavior is to have IP riding disabled.
90
00:09:42,870 --> 00:09:47,160
So this is the default behavior in this lab.
91
00:09:47,160 --> 00:09:49,690
However it was turned on.
92
00:09:49,950 --> 00:09:59,060
So we need to verify that it's off so that we can ping the pieces using the IP default gateway command.
93
00:09:59,070 --> 00:10:04,430
So can P.S. 1 ping the switch paying tendered 1 at 1 2 5 3.
94
00:10:05,220 --> 00:10:10,470
Yes it can can P.C. to ping the switch
95
00:10:14,160 --> 00:10:15,370
yes it can.
96
00:10:15,420 --> 00:10:20,670
So we successfully configured this network per our instructions.
97
00:10:20,670 --> 00:10:24,420
Don't forget to save your configurations on your devices.
98
00:10:26,590 --> 00:10:31,990
In the exam you may have to use the command copy running config startup config.
99
00:10:31,990 --> 00:10:39,070
Here I I'm simply using the old command W R but I would suggest in the exam that when you finished save
100
00:10:39,070 --> 00:10:44,090
your configurations I hope you found this video useful.
