1 00:00:00,180 --> 00:00:08,850 This lab consists of multiple tasks where you have to back up and restore configurations and operating 2 00:00:08,850 --> 00:00:11,910 systems on network devices. 3 00:00:25,140 --> 00:00:32,420 In the first part, you need to backup the running and startup configurations of the router and the 4 00:00:32,430 --> 00:00:32,980 switch. 5 00:00:33,630 --> 00:00:40,140 You also need to backup the operating systems of both the router and the switch, and then you need 6 00:00:40,140 --> 00:00:47,220 to verify that the configurations and operating systems are available on the TFTP server. 7 00:00:47,880 --> 00:00:57,630 So on the TFTP server, go to Services, TFTP and make sure that the running configurations startup configurations 8 00:00:58,080 --> 00:01:02,400 and operating systems have been backed up to the TFTP server. 9 00:01:03,180 --> 00:01:10,410 In part two, you need to create a loopback interface on the router with IP address 1.1.1.1/ 10 00:01:11,040 --> 00:01:11,770 32. 11 00:01:12,420 --> 00:01:18,240 You then need to save the routers configuration and verify that the startup configuration displays 12 00:01:18,240 --> 00:01:19,620 the loopback interface. 13 00:01:20,470 --> 00:01:29,400 Then you should copy the startup configuration that you stored in the TFTP server in task1 to the startup 14 00:01:29,400 --> 00:01:30,830 configuration of the router. 15 00:01:31,380 --> 00:01:38,430 In other words, you're going to copy the startup configuration that you previously stored on the TFTP server 16 00:01:38,880 --> 00:01:41,130 to the routers start startup configuration. 17 00:01:41,820 --> 00:01:43,050 Then you need to verify. 18 00:01:43,440 --> 00:01:48,550 Has the loopback interface been removed from the startup configuration? 19 00:01:49,080 --> 00:01:50,730 If so, why? 20 00:01:51,330 --> 00:01:57,640 You should then copy the current running configuration to the TFTP server and delete the loopback 21 00:01:57,660 --> 00:02:01,090 interface on the router and then do something similar. 22 00:02:01,260 --> 00:02:06,640 Copy the latest running configuration from the TFTP server. 23 00:02:07,140 --> 00:02:14,070 So in other words, copy the new running configuration that you backed up in step six from the TFTP server 24 00:02:14,460 --> 00:02:18,210 to the routers running configuration. Answer this question, 25 00:02:18,420 --> 00:02:22,260 Has the loopback been added back to the router config? 26 00:02:23,100 --> 00:02:25,830 Now copy the previous running configuration. 27 00:02:26,250 --> 00:02:32,610 In other words, the backup that you took in part one from the server to the running configuration of 28 00:02:32,610 --> 00:02:37,880 the router, has the loopback now been removed from the running configuration? 29 00:02:38,310 --> 00:02:39,930 Why or why not? 30 00:02:40,650 --> 00:02:46,020 So how is the running configuration acting differently to the startup configuration? 31 00:02:46,620 --> 00:02:52,220 You restore the config from the TFTP server to startup and then to running configuration. 32 00:02:52,650 --> 00:02:54,390 How did it act differently? 33 00:02:55,320 --> 00:03:02,070 In part three, you need to upgrade the routers operating system to this version of operating system 34 00:03:02,070 --> 00:03:08,320 stored on the TFTP server, but you need to leave the current operating system in flash. 35 00:03:08,760 --> 00:03:14,390 So in other words, they will now be two operating systems stored in the flash of the router. 36 00:03:14,970 --> 00:03:21,600 You need to use the relevant boot commands to ensure that the router boots using the latest operating 37 00:03:21,600 --> 00:03:22,050 system. 38 00:03:22,830 --> 00:03:29,850 So the router should now use this operating system, even though the current operating system is in 39 00:03:29,850 --> 00:03:36,990 flash. To verify this, reboot the router and confirm that the new operating system is being used 40 00:03:36,990 --> 00:03:37,830 by the router. 41 00:03:38,640 --> 00:03:45,390 So can you complete these tasks? Download the attached packet tracer file and see if you can 42 00:03:45,390 --> 00:03:47,940 complete all of these labs yourself. 43 00:03:48,510 --> 00:03:53,100 Otherwise, watch the next video where I complete these tasks.
