1 00:00:20,100 --> 00:00:26,160 In this lab we told that we need to power on the devices and then configure them. 2 00:00:26,160 --> 00:00:33,120 Per these instructions something to click on Write a one when I click on see a lie I'm told that the 3 00:00:33,120 --> 00:00:34,650 device needs to be powered on 4 00:00:37,990 --> 00:00:41,710 so I'm going to power on the device and go back to see a lie. 5 00:00:42,770 --> 00:00:45,290 And as you can see here the device is booting 6 00:00:49,410 --> 00:00:54,700 I'll do something similar with writer to turn it on and then go to see a line. 7 00:00:55,850 --> 00:01:04,180 The device is also booting up to this point when a Cisco router boots up for the first time a system 8 00:01:04,210 --> 00:01:06,730 configuration dialog is displayed. 9 00:01:06,730 --> 00:01:07,960 We don't want to use that. 10 00:01:08,080 --> 00:01:16,050 So I'm going to type no and press enter to bypass the initial configuration dialog. 11 00:01:16,330 --> 00:01:25,330 The initial configuration dialog is a wizard that allows you to configure basic settings on Cisco devices. 12 00:01:25,330 --> 00:01:29,370 We don't want to do that at the moment I'm in user mode. 13 00:01:29,470 --> 00:01:35,950 I'm going to type enable to go to privilege mode and then type confetti to go to global configuration 14 00:01:35,950 --> 00:01:44,810 mode so enable configured terminal or confetti takes me to global configuration. 15 00:01:44,830 --> 00:01:52,210 Now these devices have names right a one and write it to the prompts show Rhoda. 16 00:01:52,210 --> 00:02:00,680 So the first thing I'm going to do is configure the router as writer 1 and as I write it to in the exam 17 00:02:01,040 --> 00:02:07,370 it'll be very clear whether you need to change the device names of the devices. 18 00:02:07,370 --> 00:02:13,440 But one of the first things you're going to want to do is configure the Device name now that we've configured 19 00:02:13,530 --> 00:02:14,760 the host names. 20 00:02:14,760 --> 00:02:23,790 The next step is to configure IP addresses as shown in the diagram show IP interface brief shows us 21 00:02:23,880 --> 00:02:27,290 the interfaces on the devices. 22 00:02:27,330 --> 00:02:36,450 This interface needs to be configured with this IP address ten dot wandered wandered one slash 24 now 23 00:02:36,460 --> 00:02:38,230 before we can figure the IP address. 24 00:02:38,240 --> 00:02:41,530 Notice of the interface is shut down. 25 00:02:41,530 --> 00:02:45,970 Cisco riders by default have their interfaces shut down. 26 00:02:45,970 --> 00:02:51,670 So you need to go into interface gigabit zero slash zero slash zero and use the command. 27 00:02:51,670 --> 00:03:00,120 No shutdown or no shut to enable the interface or bring the interface up on the side. 28 00:03:00,120 --> 00:03:01,690 We can see something similar. 29 00:03:01,740 --> 00:03:07,920 Show IP interface brief notice of this interface is shut down. 30 00:03:07,930 --> 00:03:11,830 Now what you'll notice is I'm using abbreviated commands. 31 00:03:12,000 --> 00:03:19,870 So rather than typing configure terminal I'll often just type confetti and rather than typing interface 32 00:03:19,930 --> 00:03:23,090 gigabit 0 slash 0 slash 0. 33 00:03:23,350 --> 00:03:38,350 What I'll do is type int gig 0 slash 0 slash 0 or I'll type int g and press tab to get gigabit and then 34 00:03:39,100 --> 00:03:46,960 top the rest of the command use a command like no shut rather than no shut down to enable an interface 35 00:03:48,300 --> 00:03:51,780 get used to typing abbreviated commands. 36 00:03:51,990 --> 00:03:54,150 It's going to save you a lot of time. 37 00:03:54,300 --> 00:04:05,940 So at the moment both these interfaces are up up but no IP address is configured on the interface so 38 00:04:05,970 --> 00:04:15,450 interface gigabit 0 slash 0 slash 0 IP address is going to be 10 1 1 1 and then we need to specify a 39 00:04:15,450 --> 00:04:17,010 subnet mask. 40 00:04:17,430 --> 00:04:22,900 Now 255 is the decimal equivalent of eight binary ones. 41 00:04:23,060 --> 00:04:26,100 We are told to use 24 binary ones here. 42 00:04:26,790 --> 00:04:34,990 So it's eight plus eight plus eight which is 24 binary ones. 43 00:04:35,190 --> 00:04:43,980 So as an example show run interface gigabit zero slash zero slash zero on a real router shows us the 44 00:04:43,980 --> 00:04:51,480 configuration of that interface but that doesn't work on packet tracer so I'll use the command show 45 00:04:51,480 --> 00:04:52,650 run. 46 00:04:52,650 --> 00:05:01,950 So there's the configuration of gigabit 0 slash zero slash zero show IP interface gigabit zero slash 47 00:05:01,950 --> 00:05:08,850 zero slash zero shows us the IP address in this notation. 48 00:05:08,850 --> 00:05:12,460 So that's a nice way to check that you've done it right. 49 00:05:13,390 --> 00:05:23,590 On the side interface gigabit to zero slash zero slash a zero IP address 10 1 1 2 subnet mask slash 50 00:05:23,590 --> 00:05:36,290 24 show IP interface gigabit zero slash zero slash zero this command shows us the IP address of the 51 00:05:36,320 --> 00:05:49,130 device after the moment show OP only shows the local IP address in the OP cache of the device but hopefully 52 00:05:49,130 --> 00:05:54,290 at this point I'll be able to ping Radha to which I can. 53 00:05:54,290 --> 00:06:03,980 The first ping is lost because the writer needs to do an OP for the mac address of Radha to so show 54 00:06:03,980 --> 00:06:14,060 up now shows us that the local writer Radha one has learnt the MAC address of wrote it to that's associated 55 00:06:14,480 --> 00:06:25,790 with this IP address on the side show up thus Radha has learnt the MAC address of Radha one so paying 56 00:06:25,820 --> 00:06:35,170 10 1 1 1 writer 2 can ping write a 1 so we've successfully configured IP addresses as shown in the diagram 57 00:06:35,740 --> 00:06:42,880 and the writers can ping each other now we need to configure and enable password of Cisco notice on 58 00:06:42,880 --> 00:06:50,290 Route 1 when I log into the console no password is required and when I type enable note password is 59 00:06:50,290 --> 00:07:00,020 required we want to change that by using the command enable password Cisco. 60 00:07:00,310 --> 00:07:10,690 So now when I type exit and log back in and type enable notice I'm asked for the enabled password if 61 00:07:10,690 --> 00:07:18,850 I type disable and then enable again I'm asked for the privilege or enable password to get into the 62 00:07:18,850 --> 00:07:25,010 right to notice the password is shown in clear text in the running config. 63 00:07:25,180 --> 00:07:33,940 In other words anyone can see what the password is and that's why we asked to encrypt the enabled password 64 00:07:34,600 --> 00:07:42,440 before I do that I'll configure and enabled password on write it to on write it to when I type enable 65 00:07:42,550 --> 00:07:49,420 to go from user mode to privilege mode or enable mode I'm not asked for a password so enable password 66 00:07:49,420 --> 00:07:58,900 Cisco exit out of the router type enable now I have to enter the password password is shown in clear 67 00:07:58,900 --> 00:07:59,920 text. 68 00:08:00,340 --> 00:08:03,580 So now let's encrypt the enabled password 69 00:08:06,720 --> 00:08:15,590 on Route 1 we use the command service password encryption show run. 70 00:08:15,720 --> 00:08:18,330 Notice the password is now encrypted. 71 00:08:18,330 --> 00:08:25,620 This is a very weak password that stops people watching over your shoulder from learning what the password 72 00:08:25,620 --> 00:08:32,920 is so after the moment password is in clear text service password encryption 73 00:08:36,000 --> 00:08:46,250 show run password is now encrypted we then asked to configure a secret password of Cisco ONE TWO THREE. 74 00:08:46,490 --> 00:08:55,510 SO quantity enable and for this command we need to use secret specify the password as Cisco ONE TWO 75 00:08:55,510 --> 00:08:56,970 THREE. 76 00:08:57,680 --> 00:09:05,880 SO show run shows us that we have both and enable password configured as well as a secret password. 77 00:09:05,970 --> 00:09:13,970 Notice the secret password is using empty five hashing by default so you don't have to try and encrypt 78 00:09:14,070 --> 00:09:17,130 that it's done automatically. 79 00:09:17,130 --> 00:09:26,740 When I type in able now I have to enter the secret password secret passwords override enable passwords. 80 00:09:26,740 --> 00:09:32,710 So on the side I'll set the secret password exit out of the router. 81 00:09:33,060 --> 00:09:37,200 And when I log back in again I need to enter the secret password.
