1 00:00:00,940 --> 00:00:07,960 Now in a previous video we configured HAARP between switch one and switch to previous to that video 2 00:00:07,960 --> 00:00:15,700 we configure trunk links access ports and spending tree and we enhance the convergence timer's of these 3 00:00:15,700 --> 00:00:23,500 devices to improve the way that the network handles failures and the utilization of uplinks in this 4 00:00:23,500 --> 00:00:31,210 video we going to enable the GOP on switch one and switch to as well as on router three. 5 00:00:31,240 --> 00:00:34,150 Now let's say just our Pirata doesn't actually exist. 6 00:00:34,270 --> 00:00:40,490 It's only shown in the typology to show you that HAARP is configured between switch one and switch 2. 7 00:00:40,780 --> 00:00:42,710 So don't let it confuse you. 8 00:00:42,730 --> 00:00:47,170 The router is actually turned off it's only here as an icon. 9 00:00:47,350 --> 00:00:51,820 It's not actually connected to any devices in the topology at all. 10 00:00:51,820 --> 00:00:59,590 So we get enable the GOP on switch one switch to and Rodders three and then advertise a default route 11 00:00:59,650 --> 00:01:07,360 from router 3 to these two switches in a subsequent video Ali cable network address translation on router 12 00:01:07,360 --> 00:01:16,400 3 so that these devices especially the Router one or two devices acting as PCs can access the Internet. 13 00:01:16,840 --> 00:01:17,970 So let's get started. 14 00:01:18,790 --> 00:01:25,710 On switch one type enable confetti router and I can select various routing protocols. 15 00:01:25,720 --> 00:01:30,090 I'm going to select the GOP I need to specify and antonymous system number. 16 00:01:30,370 --> 00:01:35,590 If the system number is not the same the broadcast won't automatically exchange rates with each other. 17 00:01:35,860 --> 00:01:40,810 So before I go any further do show IP protocols. 18 00:01:40,810 --> 00:01:47,190 I can see that your GOP is being configured but we're not advertising any networks at the moment. 19 00:01:47,290 --> 00:01:51,170 I need to advertise networks using the network command. 20 00:01:51,460 --> 00:02:00,010 So as an example I could simply enter network 10.0 0.0 and that will enable your job on all interfaces 21 00:02:00,030 --> 00:02:01,830 in the 10 network. 22 00:02:01,830 --> 00:02:09,360 So do show IP protocols now shows me that your job is writing for networks 10. 23 00:02:09,480 --> 00:02:19,860 The idea is this and your job P is enabled on these interfaces so do show IPR jobby interfaces shows 24 00:02:19,860 --> 00:02:25,410 me that your job is enabled on villaine one violent 10 and villaine 20. 25 00:02:25,770 --> 00:02:34,590 If I removed the network command and did that command again so do show IP job interfaces I would see 26 00:02:34,590 --> 00:02:43,040 that your job is not enabled on any interfaces which means no networks will be advertised and your job 27 00:02:43,200 --> 00:02:50,410 will not form relationships with any devices on any interfaces so Network 10 again. 28 00:02:51,490 --> 00:02:51,960 Yeah. 29 00:02:52,160 --> 00:02:58,780 Now we enabled on villaine one 10 and 20 and to make it easy I'll just get back to privilege mode. 30 00:02:59,180 --> 00:03:01,790 So show IP your job. 31 00:03:02,090 --> 00:03:10,910 We've already seen the interfaces and there are other options available include neighbors at the moment 32 00:03:10,970 --> 00:03:16,510 there are no E-I GOP neighbors because I haven't enabled you GOP and any other devices. 33 00:03:17,550 --> 00:03:23,730 I can look at the typologies so show IPTA GOP typology the routes that are going to be advertised in 34 00:03:23,730 --> 00:03:31,530 your job include tendered wonder 10.0 I-Slash 24 tendered wonder 10 to 20 Flesch 24 as well as tendered 35 00:03:31,530 --> 00:03:43,010 one to one hundred its era slushed 24 show run pipe section on GOP this is the GOP configuration that 36 00:03:43,010 --> 00:03:50,900 we've done now as a rule of thumb you're going to want to use the note or just summary command to disable 37 00:03:50,990 --> 00:03:58,070 automatic summarization in the video I showed you a problem with automatic summarization and the same 38 00:03:58,070 --> 00:03:59,950 will happen with the job. 39 00:04:00,260 --> 00:04:05,040 It's good practice to disable automatic summarization in your job. 40 00:04:05,570 --> 00:04:15,120 So show run pipe section your job he all we've done is use the network command and disable automatic 41 00:04:15,120 --> 00:04:16,280 summarization. 42 00:04:16,290 --> 00:04:25,110 Now on this device automatic summarization in your job is disabled by default so notice automatic summarization 43 00:04:25,110 --> 00:04:26,120 disabled. 44 00:04:26,120 --> 00:04:35,670 Now let's prove that by doing a similar configuration on switch to serrata your job 100 network 10.0 45 00:04:35,670 --> 00:04:40,220 added 0 0 to show IP protocol. 46 00:04:40,440 --> 00:04:46,260 Just before I Precentor notice neighbor relationships have been formed between switch to and switch 47 00:04:46,260 --> 00:04:56,970 one on villaine one the last 10 and Vilain 20 but do show IP protocols shows me that all the Medek summarization 48 00:04:56,970 --> 00:04:58,320 is disabled. 49 00:04:58,410 --> 00:05:05,400 This will be dependent on the version of Ioway sketchy using switch to is routing for network 10 and 50 00:05:05,400 --> 00:05:17,430 is getting information from switch one on VLAN 10 and 20 and we land one back on switch one previously 51 00:05:17,430 --> 00:05:23,450 we were routing full network 10 but we didn't have any writing information sources. 52 00:05:24,320 --> 00:05:35,720 Now however we've got neighbor relationships on VLAN one villain 10 and Villon 20 show IP protocols 53 00:05:36,350 --> 00:05:43,070 shows me that we've got these sources of routing information show IP Japie neighbors 54 00:05:45,650 --> 00:05:52,490 so show Piaggio the neighbors shows us that we have three neighboring relationships. 55 00:05:52,490 --> 00:05:58,100 So a neighbor relationship is established on every LAN show IP route at the moment. 56 00:05:58,100 --> 00:06:04,160 We don't see any GOP rats in the running table so there are no deep entries because both these writers 57 00:06:04,160 --> 00:06:13,730 are connected physically to all networks in this typology that lets enable you know GOP on Radio 3 and 58 00:06:13,730 --> 00:06:16,160 they will advertise a rat into the typology.
