1 00:00:00,930 --> 00:00:02,400 So he has rather three. 2 00:00:03,730 --> 00:00:14,710 Will configure a hostname of router three rather interface loopback zero IPV six address 2001 colon 3 00:00:14,710 --> 00:00:21,970 face colon three colon colon one slash 64 interface gigabit zero zero. 4 00:00:24,350 --> 00:00:27,200 This should have an IP address of 2001. 5 00:00:27,200 --> 00:00:27,920 Colon two. 6 00:00:27,920 --> 00:00:28,340 Colon. 7 00:00:28,340 --> 00:00:29,420 Colon three. 8 00:00:29,900 --> 00:00:31,580 Slash 64. 9 00:00:33,170 --> 00:00:35,740 And I'll know. 10 00:00:35,750 --> 00:00:37,250 Shut the interface. 11 00:00:40,140 --> 00:00:41,430 Interfaces come up. 12 00:00:41,760 --> 00:00:43,530 Gigabit zero one. 13 00:00:45,380 --> 00:00:47,060 This should be 2001. 14 00:00:47,060 --> 00:00:50,150 Colon three, colon, colon one slash 64. 15 00:00:51,700 --> 00:00:53,950 And I'll also shut the interface. 16 00:00:54,280 --> 00:00:54,910 So. 17 00:00:57,170 --> 00:01:00,470 IPV six unicast routing needs to be enabled. 18 00:01:00,740 --> 00:01:01,700 IPV six. 19 00:01:01,700 --> 00:01:03,920 Router OSPF one. 20 00:01:08,280 --> 00:01:12,300 Rada ID, as we told here, needs to be manually configured. 21 00:01:12,300 --> 00:01:17,370 So 3333 interface gigabit zero zero. 22 00:01:17,400 --> 00:01:18,330 IPV six. 23 00:01:18,330 --> 00:01:20,250 OSPF one. 24 00:01:20,670 --> 00:01:22,770 Area zero. 25 00:01:24,680 --> 00:01:26,930 This interface needs to be an area zero. 26 00:01:27,020 --> 00:01:29,540 A neighbour relationship has been established. 27 00:01:31,230 --> 00:01:32,610 Interface loopback. 28 00:01:33,210 --> 00:01:33,800 Zero. 29 00:01:33,840 --> 00:01:35,640 I'll put that into. 30 00:01:37,980 --> 00:01:43,860 Area two and will put gigabit zero one into area two. 31 00:01:43,860 --> 00:01:50,520 So show IP OSPF protocols or other show IP protocols. 32 00:01:54,530 --> 00:01:56,570 And this is the mistake that's easy to make. 33 00:01:56,570 --> 00:01:59,750 It's IPv6 protocols rather than IP version four. 34 00:02:00,560 --> 00:02:03,860 OSPF is enabled with OSPF process ID one. 35 00:02:03,890 --> 00:02:06,050 The process numbers don't have to be the same. 36 00:02:06,050 --> 00:02:12,560 I'll configure the lost router with a different process ID, but it makes sense to keep it simple and 37 00:02:12,560 --> 00:02:16,280 use the same process ID on all your routers. 38 00:02:16,920 --> 00:02:18,360 To normal areas. 39 00:02:18,360 --> 00:02:21,440 These interfaces have been configured in the various areas. 40 00:02:21,450 --> 00:02:30,000 Show IPV six route OSPF notice three routes have been learned through OSPF and these are inter area 41 00:02:30,030 --> 00:02:36,040 OSPF routes advertised by router two using its a link local address. 42 00:02:36,040 --> 00:02:47,250 So ping 2001 colon face colon one colon colon one router three is able to ping this address. 43 00:02:47,250 --> 00:02:49,200 And what about a trace route? 44 00:02:51,020 --> 00:02:52,550 To the same address. 45 00:02:53,600 --> 00:02:58,970 We can see that we going via router two and then via router one. 46 00:02:59,360 --> 00:03:03,050 So we've configured OSPF successfully on this part of the network. 47 00:03:03,050 --> 00:03:04,550 Let's configure out of four. 48 00:03:05,360 --> 00:03:12,230 And as I mentioned, I'll configure it with a different process ID just to show you that you can do 49 00:03:12,230 --> 00:03:16,010 that, even though I'd probably want to keep it the same. 50 00:03:16,010 --> 00:03:19,640 And all routers for consistency and simplicity. 51 00:03:20,390 --> 00:03:23,090 So host is are for. 52 00:03:23,990 --> 00:03:26,540 IPV six unicast routing. 53 00:03:27,770 --> 00:03:28,340 Interface. 54 00:03:28,370 --> 00:03:29,580 Loopback zero. 55 00:03:29,600 --> 00:03:30,740 IPV six. 56 00:03:30,740 --> 00:03:32,750 Address 2001. 57 00:03:33,740 --> 00:03:39,740 Colon face colon for colon, colon one slash 64. 58 00:03:39,950 --> 00:03:41,750 Now I'm using virtual rudders here. 59 00:03:41,750 --> 00:03:48,920 You can see that it's having a problem with one of the processes, but hopefully that won't cause problems. 60 00:03:48,950 --> 00:03:54,620 As always, what I should have done is save my configurations on all my routers. 61 00:03:54,620 --> 00:03:58,010 So let's do that here in case I have to reload. 62 00:03:58,490 --> 00:03:59,060 Three. 63 00:04:01,250 --> 00:04:06,560 Not sure if you can hear that, but my CPU is taking a hammering at the moment. 64 00:04:07,660 --> 00:04:11,530 So configuration is saved on. 65 00:04:14,740 --> 00:04:15,850 The Four routers. 66 00:04:17,209 --> 00:04:20,870 So show IPV six interface brief. 67 00:04:20,959 --> 00:04:25,610 We have configured the loopback, but we haven't configured the other interfaces. 68 00:04:25,610 --> 00:04:33,110 So Interface Gigabit zero zero IPV six Address 2001 colon three colon colon two. 69 00:04:33,110 --> 00:04:34,310 Slash 64. 70 00:04:34,820 --> 00:04:39,290 No shut we've already configured. 71 00:04:42,300 --> 00:04:45,450 IPV six unicast routing. 72 00:04:45,480 --> 00:04:49,080 So now we can configure OSPF. 73 00:04:49,080 --> 00:05:00,180 So IPV six router ospf one router id in this example will be quadruple for interface gigabit zero zero 74 00:05:00,480 --> 00:05:04,080 IPV six OSPF one area. 75 00:05:05,640 --> 00:05:06,420 Two. 76 00:05:07,110 --> 00:05:10,140 And we'll do the same thing on the loopback. 77 00:05:10,980 --> 00:05:15,390 Neighbor relationship has formed so show IPV six OSPF neighbor. 78 00:05:18,500 --> 00:05:21,050 Neighbor relationship is established show. 79 00:05:21,140 --> 00:05:23,510 IPV six route. 80 00:05:23,630 --> 00:05:30,230 OSPF We've got a single intra area OSPF route. 81 00:05:30,620 --> 00:05:35,690 These two loopback are in the same OSPF area area too. 82 00:05:35,690 --> 00:05:45,500 But these loopback on router two and router one are in different OSPF areas and so is this network here. 83 00:05:45,560 --> 00:05:46,640 So ping. 84 00:05:48,350 --> 00:05:49,130 2001. 85 00:05:49,130 --> 00:05:49,670 Colin one. 86 00:05:49,670 --> 00:05:50,000 Colin. 87 00:05:50,000 --> 00:05:50,840 Colin one. 88 00:05:50,930 --> 00:05:51,590 That's right. 89 00:05:51,590 --> 00:05:54,260 A ones gigabit zero zero interface. 90 00:05:54,260 --> 00:05:55,310 That works. 91 00:05:55,880 --> 00:05:56,360 Ping. 92 00:05:56,390 --> 00:05:57,650 2001. 93 00:05:57,650 --> 00:05:58,610 Face one. 94 00:05:58,610 --> 00:05:58,910 Colin. 95 00:05:58,910 --> 00:05:59,750 Colin one. 96 00:05:59,840 --> 00:06:02,150 That's the loopback of router one. 97 00:06:02,690 --> 00:06:06,440 So debug IP and I'm going to make a mistake now. 98 00:06:06,590 --> 00:06:14,630 Debug ip icmp won't show anything because we're not sending IP version for pings. 99 00:06:14,630 --> 00:06:16,730 We are sending IP version six pings. 100 00:06:16,730 --> 00:06:19,160 So debug ipv6 ICMP. 101 00:06:20,270 --> 00:06:23,660 Notice we now get output on the debug. 102 00:06:24,260 --> 00:06:25,700 So just be careful. 103 00:06:26,540 --> 00:06:32,930 Make sure that you specify IPV six rather than IP version four when using your commands. 104 00:06:32,930 --> 00:06:33,860 So show. 105 00:06:34,850 --> 00:06:41,120 IPV six protocols there we can see that OSPF is enabled on this router. 106 00:06:41,240 --> 00:06:47,090 Show IPV six OSPF interface brief two interfaces are in OSPF. 107 00:06:48,250 --> 00:06:52,090 On Router three show ipv6 OSPF interface. 108 00:06:53,240 --> 00:06:55,590 So this is not brief. 109 00:06:55,610 --> 00:06:57,500 This is the interface command. 110 00:06:57,530 --> 00:07:00,440 And you can see that gigabyte is zero zero. 111 00:07:00,620 --> 00:07:03,830 This interface is a broadcast interface. 112 00:07:03,980 --> 00:07:08,420 The local router has a link local address of this process. 113 00:07:08,420 --> 00:07:10,310 ID is one. 114 00:07:10,340 --> 00:07:12,350 The interface is an area zero. 115 00:07:12,380 --> 00:07:15,170 Router three has a router ID of this. 116 00:07:15,320 --> 00:07:18,440 It is a backup designated router. 117 00:07:18,800 --> 00:07:27,380 The designated errata on this segment is rather two with this link local address backup designated router 118 00:07:27,380 --> 00:07:28,610 is the local router. 119 00:07:28,790 --> 00:07:31,250 Hello times and dead time as are shown here. 120 00:07:31,850 --> 00:07:36,350 Scrolling down neighbor counters, one adjacent neighbor counters. 121 00:07:36,350 --> 00:07:43,820 One neighboring router is rather two, which is the designated router on gigabit zero one. 122 00:07:43,820 --> 00:07:45,770 We see similar kind of information. 123 00:07:45,770 --> 00:07:51,200 The local router is the designated router, so router three is the designated router here, but rather 124 00:07:51,200 --> 00:07:53,870 two is the designated router here. 125 00:07:54,710 --> 00:07:57,290 Show IPV six. 126 00:07:59,370 --> 00:08:00,240 OSPF. 127 00:08:01,180 --> 00:08:05,230 This just gives us general information about OSPF version three. 128 00:08:05,530 --> 00:08:08,920 We can see the router ID and the process number. 129 00:08:09,010 --> 00:08:13,660 So we're using OSPF version three and not OSPF version two. 130 00:08:13,930 --> 00:08:16,090 We can also see a backbone area. 131 00:08:16,120 --> 00:08:19,600 Area zero one interfaces in that area. 132 00:08:19,810 --> 00:08:23,020 The spoof algorithm has been executed three times. 133 00:08:23,350 --> 00:08:24,070 There are 12. 134 00:08:24,070 --> 00:08:26,500 Liz's area two. 135 00:08:27,040 --> 00:08:29,380 There are two interfaces and area two. 136 00:08:29,950 --> 00:08:32,530 Spoof algorithm has executed three times. 137 00:08:33,440 --> 00:08:36,740 Show IPV six OSPF database. 138 00:08:37,980 --> 00:08:41,220 We have and this is where you need to be careful. 139 00:08:41,280 --> 00:08:43,770 Two routers in area zero. 140 00:08:43,890 --> 00:08:45,420 But scrolling down. 141 00:08:45,720 --> 00:08:48,960 There are also two writers in Area two. 142 00:08:49,080 --> 00:08:54,570 The databases are separate, so there's a separate database for Area two versus Area zero. 143 00:08:54,900 --> 00:09:01,980 So that's how you configure a basic IP version six network with OSPF version three.
