1 00:00:00,610 --> 00:00:07,470 His product to show IPV six Raat we haven't learnt about any Roths. 2 00:00:07,560 --> 00:00:11,360 We only have no Zerah route in the writing table. 3 00:00:12,790 --> 00:00:16,120 So let's configure the robing first. 4 00:00:17,240 --> 00:00:19,670 Configured the loopback IPV 6 5 00:00:22,370 --> 00:00:38,090 address 2001 face to code on Column 1 slash 64 interface gigabit 00 IPV 6 2001 colon one colon colon 6 00:00:38,120 --> 00:00:40,720 to slash 64. 7 00:00:41,030 --> 00:00:42,650 No shut the interface. 8 00:00:42,650 --> 00:00:43,910 Gigabit 0 1 9 00:00:48,400 --> 00:00:50,650 and the side will be 2001. 10 00:00:50,650 --> 00:01:01,870 Colon to Colon colon one and all no shut that interface show IPV six ROFFT some rats have been added 11 00:01:01,870 --> 00:01:10,600 to to the writing table of this Rodda we can see a local interface route of 2000 or one column one column 12 00:01:10,600 --> 00:01:13,050 column to slash 128. 13 00:01:13,060 --> 00:01:17,600 So that's the IP address configured on gigabit 00. 14 00:01:17,890 --> 00:01:24,080 We can see some directly connected networks such as 2001 Kahlon to Colon colon 64. 15 00:01:24,310 --> 00:01:30,500 That's this network but we don't have any SPF wrought in the writing table. 16 00:01:30,760 --> 00:01:38,040 So show IPV six ROFFT SPF shows and no SPF rots in the writing table of router 2. 17 00:01:38,560 --> 00:01:44,800 So first thing IPV 6 unit cost routing has to be enabled. 18 00:01:44,930 --> 00:01:52,770 Now as soon as I've done that on this router show run piping clewed IPV 6. 19 00:01:52,880 --> 00:02:02,140 Notice that that command has enabled IPV success which is Siska express forwarding allowing quicker 20 00:02:02,570 --> 00:02:06,190 switching of traffic from wanting to face to another. 21 00:02:06,230 --> 00:02:11,260 Let's contrast that with Rodda three which has no configuration on it. 22 00:02:14,380 --> 00:02:18,840 So show run piping clewed IPV 6. 23 00:02:19,220 --> 00:02:20,950 This Rodda has the command. 24 00:02:20,970 --> 00:02:23,190 No IPV success. 25 00:02:23,590 --> 00:02:34,740 But if we enable IPV 6 udy cost routing on the router and then do a show run Poppi include IPV 6 again. 26 00:02:34,820 --> 00:02:38,920 Notice IPV 6 Ceph has been enabled by default on this router. 27 00:02:39,290 --> 00:02:45,120 That may be different to all the rods and switches that you use in the real world. 28 00:02:45,200 --> 00:02:47,570 So just check on your devices. 29 00:02:47,720 --> 00:02:54,890 You want to use Ceph or Cisco express forwarding for quicker throughput of traffic on the serrata IPV 30 00:02:54,890 --> 00:03:08,060 6 Rodda OSPF 1 rather is PFM one Rodda ID here will be configured as 2 2 2 2 and then we'll go on to 31 00:03:08,120 --> 00:03:17,630 Gigabit 00 interface and enable OSPF on that interface in Area 1 and we'll also do something on the 32 00:03:17,640 --> 00:03:20,410 loopback. 33 00:03:20,490 --> 00:03:23,870 So the loopback will also belong to area one. 34 00:03:23,910 --> 00:03:32,260 Notice please that a neighbor relationship has been established with this neighbor on gigabit 00 Sarada 35 00:03:32,310 --> 00:03:37,310 too has formed a neighbor relationship with Rob one and one we can see something similar. 36 00:03:37,380 --> 00:03:47,970 It's form the neighbor relationship with rockety to it's on route to show my Peavey six protocol's always 37 00:03:48,280 --> 00:03:56,950 has been enabled on the router with Process ID one router ID is 1:58 to these interfaces have been put 38 00:03:56,950 --> 00:03:58,260 into OSPF. 39 00:03:58,540 --> 00:04:03,190 I forgot to put gigabit 0 one into OSPF So let's do that here. 40 00:04:04,980 --> 00:04:07,270 So show IP protocols again. 41 00:04:08,200 --> 00:04:13,190 Loop back in 0 gigabit 0 0 and 0 1 have been added to P.F.. 42 00:04:13,210 --> 00:04:18,970 We have one normal area which is area one Rudha IDs. 43 00:04:18,970 --> 00:04:23,400 This once again shows IPV 6 OSPF neighbor. 44 00:04:23,530 --> 00:04:28,840 We have a neighbor relationship with this router the neighbor relationship is full. 45 00:04:29,040 --> 00:04:36,830 The neighboring router is a designated router on the side show IP V-6 OSPF neighbor. 46 00:04:36,930 --> 00:04:43,680 It has a relationship with rodded too which is a backup designated Rodda local interfaces gigabit 0 47 00:04:43,690 --> 00:04:47,100 0 on both sides. 48 00:04:48,730 --> 00:04:57,680 Show IPV six route notice we see an OSPF wrapped in the writing table so we can do it this way. 49 00:04:57,710 --> 00:05:05,990 Show IPV 6 ROFFT OSPF to only see OSPF Roths and that Rod is showing in the writing table so we could 50 00:05:05,990 --> 00:05:17,080 not type ping and specify protocols such as IP V-6 and ping 2001 Culham face colon. 51 00:05:17,150 --> 00:05:19,740 One colon colon one. 52 00:05:19,910 --> 00:05:23,860 All we can just remove IPV 6 and specify the address. 53 00:05:23,870 --> 00:05:30,950 The road is intelligent enough to know that this is an IPV 6 IP address so we don't have to specify 54 00:05:30,950 --> 00:05:32,860 IPV V-6. 55 00:05:33,010 --> 00:05:42,220 Once again that rot has been learnt through OSPF but notice via the address it's not using this IP address 56 00:05:42,310 --> 00:05:50,880 as the next top the next top is a linked local address which is the address on Rotto ones gigabit 00 57 00:05:50,890 --> 00:05:52,180 interface. 58 00:05:52,360 --> 00:05:57,760 So this link local address is seen as the next hop from ratatouille point of view. 59 00:05:58,060 --> 00:06:03,970 The OSPF neighbor relationship is not established using IPV six global unicorn's addresses. 60 00:06:04,090 --> 00:06:14,060 They are established using a link a local addresses show IPV 6 OSPF database. 61 00:06:14,110 --> 00:06:20,880 We now have two routers in the OSPF database but Rotto one is the designated Rodda on the segment. 62 00:06:21,100 --> 00:06:24,880 So we now have IP connectivity between these two routers. 63 00:06:25,000 --> 00:06:30,820 They can ping each other's loopback and I made a mistake earlier. 64 00:06:31,280 --> 00:06:42,040 Show IPV 6 low SPF protocol notice that this interface was added to area 1 instead of area 0. 65 00:06:42,150 --> 00:06:49,550 But OSPF still functions OSPF does not require areas 0. 66 00:06:49,610 --> 00:06:57,950 If you only have a single area and that's true for always be of version 3 and always version 2. 67 00:06:58,010 --> 00:07:03,900 So this command on gigabit 0 1 needs to be changed. 68 00:07:07,870 --> 00:07:13,340 So let's remove that and put that interface 69 00:07:15,940 --> 00:07:18,370 into area 0. 70 00:07:18,760 --> 00:07:24,520 So now show IP protocol OSPF is enabled on the router. 71 00:07:24,950 --> 00:07:34,990 But notice we have areas zero as well as area 1 so they are two normal areas configured one interfaces 72 00:07:35,000 --> 00:07:39,980 and area 0 2 interfaces in area one. 73 00:07:40,010 --> 00:07:45,290 So now let's configure out a 304 and get full connectivity between these routers.
