Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:11,960 --> 00:00:20,300
So on the switch show run we need to configure additional configuration on these interfaces.
2
00:00:20,310 --> 00:00:24,000
The switched virtual interfaces on the switch.
3
00:00:24,120 --> 00:00:31,810
We need to configure what's called an IP help her address to forward DCP requests to the router.
4
00:00:32,280 --> 00:00:41,750
So there are a number of things we need to do on the switch including forwarding the DHEA HP request
5
00:00:41,750 --> 00:00:43,850
to messages to the router.
6
00:00:43,860 --> 00:00:50,040
So let's do that on Vigeland 10 and on VLAN 20.
7
00:00:50,600 --> 00:00:53,850
So firstly show run.
8
00:00:53,850 --> 00:01:01,110
Notice as prior diagram this interfaces and VLAN 10 and do this interface is in VLAN 20.
9
00:01:01,860 --> 00:01:05,350
So P.S. One is in VLAN 10.
10
00:01:05,370 --> 00:01:07,800
P.S. 2 is in VLAN 20.
11
00:01:08,100 --> 00:01:09,240
And that's correct.
12
00:01:09,240 --> 00:01:11,850
Per the configuration shown here.
13
00:01:13,790 --> 00:01:22,550
Now that we've configured the IP help her addresses DCP requests will be forwarded to the router but
14
00:01:22,640 --> 00:01:33,480
the router needs to know about those networks if a rider receives a DHB request from a network that
15
00:01:33,480 --> 00:01:39,210
it's not aware of it won't allocate IP addresses on the router.
16
00:01:39,210 --> 00:01:50,620
I'm going to create a static Grant pointing to the switch for Network 10 1 10 0 as well as 10 1 20 0
17
00:01:51,950 --> 00:01:52,960
so after the moment.
18
00:01:52,960 --> 00:02:02,370
Now at the writing table contains those two static routes in addition to the directly connected interfaces
19
00:02:02,940 --> 00:02:09,580
so the router should be able to ping the switches switched virtual interfaces or SFE eyes which it can.
20
00:02:09,750 --> 00:02:15,090
So the rod is able to ping this IP address as well as this IP address.
21
00:02:15,090 --> 00:02:21,750
Don't forget to add Rance either using a dynamic routing protocol or something else so that you have
22
00:02:21,750 --> 00:02:25,260
IP connectivity in your network.
23
00:02:25,260 --> 00:02:32,760
We've been told that pieces need to be able to ping the loop back of wrought a one rod one has an IP
24
00:02:32,760 --> 00:02:37,740
address of wandered wandered wandered one configured on the loop back
25
00:02:40,680 --> 00:02:44,580
the switch doesn't know about that network.
26
00:02:44,580 --> 00:02:46,470
So we would have to add a static round
27
00:02:49,140 --> 00:02:55,900
or enable a writing protocol such as I was P.F. to allow the devices to ping each other.
28
00:02:55,980 --> 00:03:00,440
So now the switch keeping the loop back of the router.
29
00:03:00,510 --> 00:03:05,400
In this example I'm using static routs but you could have used a writing protocol such as over SPF or
30
00:03:05,400 --> 00:03:08,000
rip.
31
00:03:08,030 --> 00:03:14,510
Another thing we need to do on the switch is enable IP routing when traffic is sent from Vila intend
32
00:03:14,570 --> 00:03:15,940
to VLAN 20.
33
00:03:16,040 --> 00:03:22,820
The switch needs to do the interview lan routing of that traffic so into VLAN routing needs to be enabled
34
00:03:23,270 --> 00:03:25,940
by using the IP routing command.
35
00:03:26,240 --> 00:03:35,750
The switch needs to be configured to route from one switch to a virtual interface to another so hence
36
00:03:36,410 --> 00:03:43,690
we add the command IP routing to the switches configuration.
37
00:03:43,700 --> 00:03:51,080
So now let's test all the pieces he's able to get IP addresses from the DCP server and ping the loop
38
00:03:51,080 --> 00:03:53,000
back of the router.
39
00:03:53,090 --> 00:04:01,700
The first thing we need to do on the P.C. is ensure that it's using DCP and then we need to ensure that
40
00:04:01,700 --> 00:04:04,780
it's retrieved an IP address through DCP.
41
00:04:04,940 --> 00:04:12,000
We can confirm that by using the command IP config notice in this example it's retrieved an IP address
42
00:04:12,000 --> 00:04:14,210
of tendered wonder tender tendered 18.
43
00:04:14,390 --> 00:04:16,710
Can it ping the switch.
44
00:04:16,710 --> 00:04:18,250
Yes it can.
45
00:04:18,330 --> 00:04:22,380
Can it paying the router yes it can.
46
00:04:22,380 --> 00:04:24,960
Can it ping the loop back of the router.
47
00:04:24,960 --> 00:04:26,460
Yes it can.
48
00:04:26,460 --> 00:04:28,470
So that looks great.
49
00:04:28,470 --> 00:04:34,820
What about PCI to we need to configure it to use DHEA P.
50
00:04:34,870 --> 00:04:42,480
You can see here that it's already been allocated a gateway and DNS server on the desktop.
51
00:04:42,480 --> 00:04:49,860
We can go to a command prompt and we can use the command IP config to verify whether it got an IP address
52
00:04:49,860 --> 00:04:51,190
through DCP.
53
00:04:51,330 --> 00:04:52,770
It has.
54
00:04:52,770 --> 00:04:56,100
So can it ping the default gateway the switch.
55
00:04:56,100 --> 00:04:57,400
Yes it can.
56
00:04:57,450 --> 00:05:00,860
Can it paying the routers Ethernet interface.
57
00:05:00,870 --> 00:05:02,220
Yes it can.
58
00:05:02,220 --> 00:05:04,310
Can it ping the writers loop back address.
59
00:05:04,320 --> 00:05:05,190
Yes it can.
60
00:05:07,140 --> 00:05:08,280
So that's looking great.
61
00:05:08,340 --> 00:05:11,410
What about the piece he's pinging each other.
62
00:05:11,630 --> 00:05:15,300
So here's P.S. One yes.
63
00:05:15,300 --> 00:05:27,740
P.S. two IP address of P.S. One is 10 dot one attended 18 ping tendered one to tender 18 that works.
64
00:05:27,740 --> 00:05:33,430
IP address on the side is tendered one to twenty dot 13.
65
00:05:33,660 --> 00:05:38,030
So can P.S. 1 ping tendered one to twenty dot 13.
66
00:05:38,180 --> 00:05:43,290
Yes it can so at this point we've got to the lab working
67
00:05:45,960 --> 00:05:54,830
so can write a one paying P.S. To yes it can cannot ping P.S. 1
68
00:05:57,810 --> 00:06:08,550
yes it can we can use the command help to C available commands on the P.S. One of those commands is
69
00:06:08,550 --> 00:06:14,400
trace round so trace right to the back of the rudder.
70
00:06:14,610 --> 00:06:19,580
Notice the traffic goes to the switch and then it goes to the router
71
00:06:22,820 --> 00:06:29,830
trace ranch to the rota same happens here
72
00:06:33,560 --> 00:06:42,350
what happens if we trace two pieces two from P.S. One trace goes via the switch so I'm happy with that
73
00:06:42,850 --> 00:06:50,490
we've successfully configured the network don't forget to save your configuration when you've finished
74
00:06:51,060 --> 00:06:56,080
with your lab I always do that in the exam just to be sure.
75
00:06:56,430 --> 00:06:59,730
I hope you found this video and lab useful.
