1 00:00:00,700 --> 00:00:08,010 Let's start with the access switches switch 3 and switch 4 on not going to do in TV land rotting. 2 00:00:08,200 --> 00:00:10,680 These are going to be configured as a layer 2 switches. 3 00:00:10,750 --> 00:00:20,020 So I should change the symbol of the switches to be simple ethernet switches. 4 00:00:20,060 --> 00:00:26,010 They are simply going to be late to switches that provide connectivity to the rest of the network. 5 00:00:26,030 --> 00:00:33,880 So change the symbol of both the switches. 6 00:00:34,030 --> 00:00:41,620 They will have one IP address configured and that IP address is only used for management purposes. 7 00:00:41,770 --> 00:00:50,470 So the IP address configured on the switches is only to allow telnet or S-sh to the switches for management 8 00:00:50,470 --> 00:00:51,700 purposes. 9 00:00:51,760 --> 00:00:58,710 They're not going to do any kind of routing user devices shouldn't typically be able to ping teleco 10 00:00:58,720 --> 00:01:08,910 S-sh to the Access switches so on switch three conforte interface a villain one this is known as a switched 11 00:01:08,930 --> 00:01:18,670 a virtual interface or vi type do show IP interface brief on the switch and scroll down you can see 12 00:01:18,670 --> 00:01:29,800 that the FBI has been raided but it was shut down previously when I did the command show interface brief 13 00:01:30,220 --> 00:01:34,330 the FBI interface was not created. 14 00:01:34,610 --> 00:01:42,410 So by using the command interface villaine one I've created this switch of virtual interface. 15 00:01:42,410 --> 00:01:49,670 So IP address tendered one to 100 top three subnet mask is going to be slashed 24 and I need to know 16 00:01:49,670 --> 00:02:01,760 shut the VI because by default it's administratively down top and ping before I do a ping show IP interface. 17 00:02:01,870 --> 00:02:05,390 Grief notice the interface is now up. 18 00:02:05,530 --> 00:02:13,420 So I should be able to ping myself ten one one hundred three and I can still save that config and then 19 00:02:13,420 --> 00:02:17,770 I'll go to search for once again show IP interface brief 20 00:02:20,660 --> 00:02:28,520 No VI currently exists only the physical interfaces interface Villon one IP address. 21 00:02:28,730 --> 00:02:32,720 In this example it will be 10 to one 104. 22 00:02:33,470 --> 00:02:46,280 So IP address 10 1 to 100 for slice 24 mosque no shut it save the conflict interface villaine one has 23 00:02:46,670 --> 00:02:47,420 come up. 24 00:02:47,510 --> 00:02:48,700 As you can see over there 25 00:02:52,330 --> 00:03:00,610 paying tandoor one to one hundred or three Ping's succeeds the first ping failed because the switch 26 00:03:00,610 --> 00:03:06,130 had to do an app for the Mac address of switch 3 but notice switch 4. 27 00:03:06,280 --> 00:03:09,140 He's now able to ping switch three. 28 00:03:09,310 --> 00:03:14,200 And by the same token switch three is now able to ping switch four. 29 00:03:14,650 --> 00:03:22,790 So that's a good sign because it means our links are up in a moment I'll discuss CGP and LDP will Siskin 30 00:03:22,810 --> 00:03:28,300 discovery protocol and Nicolay discovery protocol and show you how to check the connections between 31 00:03:28,300 --> 00:03:32,080 switches on switch one and switch to. 32 00:03:32,410 --> 00:03:40,480 We need to configure multiple IP addresses one per line because of these switches we'll be doing interval 33 00:03:40,480 --> 00:03:41,350 and routing. 34 00:03:41,530 --> 00:03:51,560 So switch one show IP interface brief at the moment no feelings are configured. 35 00:03:51,790 --> 00:04:03,790 So interface VLAN 1 IP address 10 1 100 1 2 4 5 2 4 5 0 no shut interfaces and 36 00:04:07,430 --> 00:04:23,190 10 IP address 10 1 to one slash twenty four no shut interface villain 20 or interface violent 20 rather 37 00:04:23,850 --> 00:04:28,800 IP address change at $1.20 one slash twenty four. 38 00:04:29,190 --> 00:04:43,540 No shut controls or controls that show IP interface brief at the moment only villain one is up and 10 39 00:04:43,550 --> 00:04:45,560 and violent 20 or down. 40 00:04:45,920 --> 00:04:52,980 And that's because we don't have any interfaces configured in a violent 10 or violent 20. 41 00:04:53,240 --> 00:04:58,790 I'm going to show you in a moment how to explicitly configure these Portus trunk ports and then we should 42 00:04:58,790 --> 00:05:02,500 see that those files come up. 43 00:05:03,020 --> 00:05:07,170 Switch to show IP interface. 44 00:05:07,220 --> 00:05:21,360 Brief no is Fiore's interface VI interface the line 1 IP address 10 dot one dot 100 to 24. 45 00:05:21,830 --> 00:05:33,370 No shut interface the plan 10 IP address 10 to 1 to 10 to 24. 46 00:05:33,590 --> 00:05:52,600 No shut in to face violent 20 IP address tendered one to twenty to 24 no shut and show IP interface. 47 00:05:52,650 --> 00:05:57,370 Brief once again the line one is up. 48 00:05:57,370 --> 00:06:00,050 Vigeland ten and violent 20 on down. 49 00:06:00,310 --> 00:06:08,200 And that's once again because when we use the command show interface gigabit 00 switch port as an example. 50 00:06:08,200 --> 00:06:16,060 You'll notice that the port is configured for villaine one but no other villains have been explicitly 51 00:06:16,210 --> 00:06:18,160 configured across this port. 52 00:06:18,310 --> 00:06:20,920 The access villanies villaine one by default. 53 00:06:20,950 --> 00:06:28,360 If DTP or dynamic trunk protocol doesn't negotiate with the other side to form a trunk trunking in native 54 00:06:28,510 --> 00:06:30,640 land is villaine one by default. 55 00:06:30,850 --> 00:06:40,330 So we only have interface Villon one up the other interfaces are down but as that time management villaine 56 00:06:40,360 --> 00:06:45,780 we were OK to use that for testing so I can switch to ping switch one. 57 00:06:45,790 --> 00:06:50,420 Yes it can should be able to ping itself which it can. 58 00:06:50,420 --> 00:06:53,570 What about switch 3 which it can. 59 00:06:53,580 --> 00:06:56,940 And what about switch for yes it can. 60 00:06:57,220 --> 00:07:00,840 So we have IP connectivity in our network. 61 00:07:00,880 --> 00:07:02,640 The switches can ping each other. 62 00:07:02,980 --> 00:07:07,470 Let's do another test on which one can ping itself. 63 00:07:07,480 --> 00:07:14,450 Yes can Kennett's pings switch to yes it can switch three yes it can switch. 64 00:07:15,030 --> 00:07:18,380 Yes it can and I'll save the config. 65 00:07:18,660 --> 00:07:27,480 So we've configured IP addresses on the switches can the switches ping router 3 which is in the management 66 00:07:27,770 --> 00:07:28,950 plan. 67 00:07:29,380 --> 00:07:39,190 So Sichuan once again paying 10 1 100 2 5 3 2 5 3 rather yes it can. 68 00:07:39,370 --> 00:07:44,170 So which one can ping this IP address of router 3. 69 00:07:44,210 --> 00:07:52,940 Now these routers acting as PCs are going to be put in two separate villans so will do the pinging when 70 00:07:52,940 --> 00:07:55,960 we configure those devices in a separate Villon. 71 00:07:56,030 --> 00:08:01,280 At the moment we haven't got violent when configured properly in the network so we can test connectivity 72 00:08:01,640 --> 00:08:03,770 between our PCs and the switches.
