1 00:00:01,080 --> 00:00:02,160 So let's configure 2 00:00:04,330 --> 00:00:13,870 a login banner. So banner login specify the delimiting character, which in this case is going to be 3 00:00:13,870 --> 00:00:17,950 a hash or pound and I'll say login banner. 4 00:00:21,640 --> 00:00:29,900 Specify the delimiting character to end the message, so hash or pound, so previously when we telnet 5 00:00:29,920 --> 00:00:35,950 it to router 2 we saw the message of the day banner and then we were prompted for our password. 6 00:00:37,110 --> 00:00:46,470 Now, when we turn it back, we see firstly message of the day and then a log in banner and then our 7 00:00:46,560 --> 00:00:47,850 authentication information. 8 00:00:48,780 --> 00:00:50,130 Now on the console, 9 00:00:52,300 --> 00:00:59,740 notice the banner message of the day is displayed, but no, login banner is displayed, so it's 10 00:00:59,740 --> 00:01:08,680 different to what we saw on the VTY line, and that's because we didn't configure any kind of authentication 11 00:01:08,980 --> 00:01:09,880 on the console. 12 00:01:11,350 --> 00:01:19,870 So if I now specify a password on the console and then login, we see both the message of the day banner 13 00:01:19,990 --> 00:01:24,010 as well as the login banner and then we're prompted for our password. 14 00:01:24,460 --> 00:01:30,990 So this is shown when I log in is configured, in other words, when you're prompted to enter your password. 15 00:01:31,510 --> 00:01:34,000 So we see a message of the day first, then login 16 00:01:34,000 --> 00:01:38,520 banner, banner exec. 17 00:01:41,140 --> 00:01:43,750 So let's say exec banner, 18 00:01:48,300 --> 00:01:52,020 delimiting character be back to global config mode, 19 00:01:55,050 --> 00:02:01,710 telnet back to the router, we see message of the day, login password prompt, and 20 00:02:02,130 --> 00:02:05,820 when we now login, we see the exec banner. 21 00:02:06,150 --> 00:02:14,190 So the banner is only displayed after log in on the console of RAW to receive the message of the day 22 00:02:14,680 --> 00:02:15,680 log in banner. 23 00:02:15,990 --> 00:02:17,250 We put a password in. 24 00:02:17,700 --> 00:02:21,240 After entering our password, we see the banner. 25 00:02:21,540 --> 00:02:26,400 So exact banner is only displayed after successful authentication. 26 00:02:29,400 --> 00:02:35,250 Now, generally, you're not going to create lots of banners, you may, as an example, just use one 27 00:02:35,250 --> 00:02:41,490 of them, such as the Log-in banner or the banner or message of the day banner. 28 00:02:42,690 --> 00:02:49,630 It is important, however, that you specify some kind of banner on your routers, so as an example, 29 00:02:49,630 --> 00:02:56,220 if we telnet from about a two to one in this example, we need to set up a password. 30 00:02:56,460 --> 00:03:04,620 So a line VTI zero to four login password, Sasko and Telnet back again. 31 00:03:05,520 --> 00:03:10,890 We are not shown any warning messages about not accessing this router. 32 00:03:11,880 --> 00:03:19,140 So we should have some kind of banner, which may be something such as a login banner stating that if 33 00:03:19,140 --> 00:03:24,780 you access this router, I will find you. 34 00:03:29,160 --> 00:03:37,170 And we can imagine what we would say then I wouldn't put that on this video, but I will find you and 35 00:03:37,170 --> 00:03:38,710 do something nasty to you. 36 00:03:39,670 --> 00:03:47,790 So now when we tell it to the radar notice, it says if you access this router, I will find you and 37 00:03:47,790 --> 00:03:49,500 destroy you or something. 38 00:03:50,510 --> 00:03:57,620 I should obviously talk to your lawyer, solicitor, attorney, whichever, Temmuz, you should talk 39 00:03:57,620 --> 00:04:03,610 to someone in the legal department to get the proper phrase to add to this message. 40 00:04:04,100 --> 00:04:07,820 So that's banners, to sum up 41 00:04:10,370 --> 00:04:18,440 we have an exec banner, message of the day banner, and login banner, message of the day is typically used 42 00:04:18,470 --> 00:04:24,770 typically used to display some kind of message of that day, such as the router is going to be taken offline. 43 00:04:25,250 --> 00:04:33,650 Login is used before a login prompt and exec is shown after logging when the exec process starts. 44 00:04:34,310 --> 00:04:38,270 Don't forget, your delimiting character shouldn't be a character used in your message. 45 00:04:38,720 --> 00:04:44,270 So as an example, if I specify O, and then say my Cisco router. 46 00:04:45,460 --> 00:04:47,920 It immediately ends the message at this point. 47 00:04:48,970 --> 00:04:55,330 So if I telnet to the router notice, my message of the day banner has been changed to this. 48 00:04:55,930 --> 00:04:57,640 Now I didn't specify message of the day 49 00:04:59,650 --> 00:05:01,810 but do show run pipe begin banner, 50 00:05:04,160 --> 00:05:11,690 Shows us that that's what's been configured in the output on the show run notice the hash or pound was 51 00:05:11,690 --> 00:05:17,420 changed to ^C to indicate the start and end of the message. 52 00:05:17,960 --> 00:05:20,790 That's useful when you want to do a copy and paste. 53 00:05:21,080 --> 00:05:23,180 So as an example, we could copy this 54 00:05:27,140 --> 00:05:30,140 and on router 1, we could paste that message. 55 00:05:31,440 --> 00:05:42,510 So now let me telnet to router, notice the login banner displays and the exec banner displays.
