1
00:00:09,000 --> 00:00:15,660
This is one of multiple videos discussing layer 3 switching in a previous video I showed you how to

2
00:00:15,660 --> 00:00:19,950
configure a switch with Layer 3 functionality.

3
00:00:20,160 --> 00:00:28,910
So I showed you how to enable IP routing on a switch to allow that switch to rot between one villain

4
00:00:28,980 --> 00:00:30,330
and another.

5
00:00:30,330 --> 00:00:38,200
We also configured two routers to act as PCs and we were able to ping from one router to another.

6
00:00:38,250 --> 00:00:46,740
What I'll do now is extend the topology by bringing in some Daka PCs.

7
00:00:46,820 --> 00:00:54,150
These are essentially lightweight PCs that allow us to boot up Linux very quickly.

8
00:00:54,170 --> 00:00:56,200
So what I'll do on the first PC

9
00:00:59,030 --> 00:01:02,420
is configure it in a fourth villaine

10
00:01:05,720 --> 00:01:17,380
so I'll give it an IP address of 10 1 for one and a default gateway of 10 1 4 2 5 4 closest set to the

11
00:01:17,380 --> 00:01:32,090
DNS server to 10 1 4 2 5 4 I clicked safe all connect the PC to Gigabit to 0 to on the switch.

12
00:01:32,130 --> 00:01:35,940
So these two ports are in veel and two and three.

13
00:01:36,060 --> 00:01:45,450
And what we'll do now is configure this port in villaine for I'll start up the dock a PC and open up

14
00:01:45,450 --> 00:01:46,590
a console to it.

15
00:01:47,590 --> 00:01:54,090
So here's the console I-F config shows us the IP address of the PC.

16
00:01:54,190 --> 00:01:58,960
One of the advantages of Daka is that it boots up extremely quickly.

17
00:01:58,960 --> 00:02:01,700
So it was almost an instant boot.

18
00:02:01,720 --> 00:02:06,910
Now the PC can ping the switch because we need to configure the switch.

19
00:02:06,990 --> 00:02:11,360
So at the moment pings are failing.

20
00:02:11,510 --> 00:02:16,080
So go into the switch and have a look at the interfaces configured.

21
00:02:16,100 --> 00:02:18,890
So show IP interface brief.

22
00:02:19,340 --> 00:02:27,860
Notice we don't have a layer 3 interface in the violent for we need to configure the IP address on the

23
00:02:27,860 --> 00:02:32,210
switch to allow that PC to paying out a villain for.

24
00:02:32,600 --> 00:02:40,940
We also need to configure the landfall and put the interface into villain for so Confiteor feline for

25
00:02:41,630 --> 00:02:51,080
show veel and brief we've now created a villain for and it's been added to the villain database.

26
00:02:51,080 --> 00:02:57,530
That however does not create the VI or virtual switched interface.

27
00:02:57,530 --> 00:03:04,920
We need to type interface a villain for to create the Fiori and configure the IP address on the switch.

28
00:03:07,970 --> 00:03:12,890
So show IP interface brief.

29
00:03:12,920 --> 00:03:18,780
The FBI has created IP addresses assigned but the interface is down.

30
00:03:19,370 --> 00:03:28,660
So we need to know shut it show the interface brief again allows us to see the interface but it's currently

31
00:03:28,660 --> 00:03:40,810
down because no interfaces have been allocated to that villain so we need to put this interface into

32
00:03:42,070 --> 00:03:48,800
Villon for the switchboard access the landfall.

33
00:03:48,810 --> 00:03:55,500
Now when we use the command show IP interface brief we should see that this interface comes up that

34
00:03:55,500 --> 00:04:03,600
may not happen immediately but after a while we should see that that interface comes up assuming that

35
00:04:04,960 --> 00:04:14,710
gigabit 0 to is in the right to Villon which it is kind of seeming that that interfaces up pup which

36
00:04:14,710 --> 00:04:21,360
it is noticed now the landfall is up set back on the PC.

37
00:04:22,750 --> 00:04:33,540
Previously the PC couldn't its hold gateway but now it can and hopefully it will be able to ping right.

38
00:04:33,560 --> 00:04:35,870
To which it can.

39
00:04:36,360 --> 00:04:40,040
And we can prove that by looking at Rodda too.

40
00:04:40,170 --> 00:04:52,020
I'm currently running a debug to show D-bag on route to shows that IP I seem debugging is enabled so

41
00:04:52,020 --> 00:05:01,350
I should be able to ping road to and see the debugs which we do.

42
00:05:01,930 --> 00:05:09,600
We should also be able to paying Grado one which we can once again this PC has an IP address of 10 1

43
00:05:09,610 --> 00:05:14,150
for one on the road to acting's PC to.

44
00:05:14,160 --> 00:05:18,050
We should be able to paying that PC which we can.

45
00:05:18,230 --> 00:05:28,480
So we've now enabled three villains on the slave three switch I'll configure a full thing to face and

46
00:05:28,480 --> 00:05:38,840
connected to to the second Daka PC I'll change the IP address of that PC.

47
00:05:42,220 --> 00:05:55,620
To 10 1 5 to 1 default gateways 10 1 5 2 5 4 and all set the DNS server to tend to add 1.5 to 2 5 4

48
00:05:57,160 --> 00:06:04,430
clicks save startup the PC open up a console to get PCs booted.

49
00:06:04,430 --> 00:06:17,940
So I-F config IP address is 10 1 5 1 PC will not be able to paying the first PC on the left until we've

50
00:06:17,940 --> 00:06:27,620
configured the switch so configured the switch while leaving that ping going in the background.

51
00:06:28,040 --> 00:06:36,600
So first thing we need to do is configure a V line so conforte villain 5 in this case.

52
00:06:36,600 --> 00:06:46,430
So show V line brief villaine 5 is created PC can still not paying the other PC yet.

53
00:06:47,810 --> 00:06:55,650
Because we have to put the interface into the right v LAN gigabit.

54
00:06:55,720 --> 00:07:08,000
0 3 is currently in Villalon 1 so interface gigabit to 0 3 switch port access a villain 5 show interface

55
00:07:08,000 --> 00:07:15,060
could give it to zero or three switch port the port is now in Villon five.

56
00:07:15,470 --> 00:07:22,940
But the PC can still not paying PC one because we have to create a switched virtual interface.

57
00:07:22,940 --> 00:07:27,890
We have a switch to a virtual interface for villaine for but not for Wii land 5.

58
00:07:27,890 --> 00:07:36,980
So interface and 5 IP address 10 1 5 2 5 4 on no shutter.

59
00:07:39,190 --> 00:07:48,430
Interface villaine 5 has come up Schoharie spending tree ports of forwarding and pings are starting

60
00:07:48,430 --> 00:07:49,630
to succeed.

61
00:07:50,190 --> 00:07:56,460
So a PC to can ping PC one.

62
00:07:56,690 --> 00:08:07,180
So I've now got four interfaces on the slave three switch configured into villaine rotting I've configured

63
00:08:07,190 --> 00:08:11,660
the villans and configured into villans rotting on the switch.

64
00:08:11,660 --> 00:08:14,440
In other words it's acting as a layer 3 switch.

65
00:08:14,990 --> 00:08:17,480
That's because the IP writing is enabled.

66
00:08:17,510 --> 00:08:23,460
If I disable IP routing on the switch the pings will fail.

67
00:08:23,780 --> 00:08:30,950
Notice the sequence numbers at forty nine men to stop they define enable IP routing.

68
00:08:30,980 --> 00:08:33,990
Notice the pings start succeeding once again.

69
00:08:35,530 --> 00:08:41,890
You need to have IP routing enabled on a switch to allow it to do into Villano routing as well as to

70
00:08:41,890 --> 00:08:44,750
allow it to support routing protocols.

71
00:08:45,280 --> 00:08:50,320
So that was an example of how to configure a layer 3 switch into VLAN routing.

72
00:08:50,320 --> 00:08:54,600
I hope you found the video useful if it's been of benefit to you.
