1 00:00:00,893 --> 00:00:06,410 In the previous video, we already learn how to configure multiple router at once, 2 00:00:06,795 --> 00:00:12,980 which is we configure interface loopback0 on router 1 until router 5. 3 00:00:13,795 --> 00:00:20,454 But the problem is, we still need to check the interface on each router one by one. 4 00:00:21,466 --> 00:00:28,010 Now in this video, we are going to create a network automation script to check the interface 5 00:00:28,010 --> 00:00:30,214 on all router at once. 6 00:00:30,850 --> 00:00:39,955 This is easy, here after configuring ip address, we can type a command to show interface, 7 00:00:40,726 --> 00:00:46,505 so here show ip interface brief exclude unassign. 8 00:00:47,643 --> 00:00:51,545 Don’t forget to use \n or enter here. 9 00:00:52,961 --> 00:00:58,440 Let’s also print a divider here, so the output will be good. 10 00:01:02,704 --> 00:01:09,684 And for the loopback, let’s try to create loopback1, and the ip address let’s say 11 00:01:09,684 --> 00:01:16,608 10.2.1.x. Here we also need to use time sleep. 12 00:01:21,956 --> 00:01:25,780 Save, back to terminal, 13 00:01:27,000 --> 00:01:28,948 Let’s execute the script. 14 00:01:33,364 --> 00:01:35,258 Just enter enter here. 15 00:01:39,119 --> 00:01:41,693 Here we can see that we get an error. 16 00:01:41,962 --> 00:01:44,183 Invalid input detected. 17 00:01:44,891 --> 00:01:46,364 Why this is error? 18 00:01:46,642 --> 00:01:53,031 Because now we are in the configuration mode, so we need to use do. 19 00:01:53,810 --> 00:02:05,073 Let’s add do here, and then let’s say we will create loopback 2, and the ip address is 3. 20 00:02:06,549 --> 00:02:14,108 Save, back to terminal, and then let’s execute the script again. 21 00:02:14,762 --> 00:02:16,582 Just enter enter here. 22 00:02:19,995 --> 00:02:21,794 Okay this is success. 23 00:02:22,332 --> 00:02:28,726 We are success to configure loopback2 with ip address 10.3.1.1 on router 1, 24 00:02:29,183 --> 00:02:34,821 and here we can see that we already have loopback0 until loopback2 on router 1. 25 00:02:36,000 --> 00:02:42,089 Router 2, we also have loopback0 until loopback2, the ip address is correct 26 00:02:43,155 --> 00:02:49,271 Router 3, we also have loopback0 until 2, the ip address is correct. 27 00:02:49,845 --> 00:02:52,623 Router 5 is also correct. 28 00:02:53,582 --> 00:02:59,284 Okay so now we are success to doing looping to show interface on all router. 29 00:03:00,000 --> 00:03:02,295 I think enough for this video 30 00:03:02,537 --> 00:03:05,915 Thank you for watching and see you on the next video.
