1 00:00:11,730 --> 00:00:18,540 This video I'm going to demonstrate how OSPF version 3 Radice conform neighbor relationships without 2 00:00:19,170 --> 00:00:22,890 manually configuring IP addresses on interfaces. 3 00:00:22,950 --> 00:00:29,520 In other words in the topology we'll form a neighbor relationship between Rotto one and Rodda two without 4 00:00:29,730 --> 00:00:35,790 configuring IP version 6 addresses on the gigabit 00 interfaces. 5 00:00:35,790 --> 00:00:42,270 This will demonstrate how a way SPF forms neighbor relationships using link local addresses and doesn't 6 00:00:42,270 --> 00:00:48,690 require IP version 6 addresses to be configured or IP version 4 addresses. 7 00:00:48,810 --> 00:00:52,400 So in the apology the two routers have just booted up. 8 00:00:52,500 --> 00:00:58,250 There is no configuration on the routers. 9 00:00:58,320 --> 00:01:04,770 I'll bypass the initial configuration dialog so that we can configure the routers manually so the right 10 00:01:04,770 --> 00:01:13,170 on the left will call rodded one show IP route shows us that they are no IP version formats available 11 00:01:13,170 --> 00:01:21,450 on this router show IPV 6 raht shows us that there are no IP version 6 Roths available on the Sprouter 12 00:01:21,630 --> 00:01:22,670 at the moment. 13 00:01:23,510 --> 00:01:28,880 These routers have just booted up again with no configuration. 14 00:01:28,880 --> 00:01:39,690 So show IP Brauch no IP version for Roth's show IPV 6 route no IP version 6 runs show IP interface brief 15 00:01:40,470 --> 00:01:50,940 No IP addresses configured on of one show IPV 6 interface brief shows us that they on no IP version 16 00:01:50,940 --> 00:01:51,830 6 addresses 17 00:01:55,200 --> 00:02:02,720 same on the side show IP interface brief No IP version for addresses show IPV 6 interface brief No IP 18 00:02:02,720 --> 00:02:05,740 version 6 addresses configured. 19 00:02:05,800 --> 00:02:15,890 OK so IPV 6 unicast routing needs to be enabled for us to use SPF what we'll do now is enable what we 20 00:02:15,890 --> 00:02:19,570 speak as a routing protocol the router will complain. 21 00:02:19,630 --> 00:02:28,450 As you can see there are no Rodda ID can be selected and that's because we have no IP version 4 addresses 22 00:02:28,470 --> 00:02:40,340 configured so I need to select a route ID in dotted decimal notation such as the following IPV 6 unit 23 00:02:40,370 --> 00:02:49,310 cost routing IP V-6 Rodda SPF 1. 24 00:02:49,320 --> 00:02:52,300 Once again we need to configure a route ID. 25 00:02:52,520 --> 00:03:03,160 I'll configure this side as two door to door to talk to show IPV six SPF interface brief shows us that 26 00:03:03,190 --> 00:03:08,060 OSPF is not enabled on any interfaces on the router. 27 00:03:08,440 --> 00:03:11,210 What we have to do is go on to interface's 28 00:03:14,270 --> 00:03:18,490 and enable IPV 6 on an interface 29 00:03:21,990 --> 00:03:36,020 and then enable OSPF on that interface on the side to kickabout 0 0 IP V-6 enable to enable IP V-6 on 30 00:03:36,020 --> 00:03:46,380 the gigabit 00 interface and then IPV 6 OSPF process ID is one area we'll set to zero. 31 00:03:47,030 --> 00:03:58,310 So now show IPV 6 OSPF interface brief shows us that OSPF is enabled on gigabit 0 0 with a process id 32 00:03:58,310 --> 00:04:01,460 of one in area zero. 33 00:04:02,030 --> 00:04:11,240 At the moment the stage is down and thats probably because I didn't enable the interface so let's do 34 00:04:11,240 --> 00:04:12,690 that. 35 00:04:13,670 --> 00:04:19,780 So now show IP V-6 OSPF interface brief. 36 00:04:19,780 --> 00:04:24,890 Notice the stage is set to wait all no shut the interface on the side. 37 00:04:24,970 --> 00:04:38,990 Show IP the CICS interface who is P.F. interface brief OSPF is enabled on gigabit to 00 in area 0 using 38 00:04:39,230 --> 00:04:41,140 P.F. process 1. 39 00:04:41,270 --> 00:04:44,360 The state is white at the moment. 40 00:04:44,360 --> 00:04:56,040 Sure IP V-6 neighbor we are forming a new relationship with a broad with neighbor ID wondered wondered 41 00:04:56,040 --> 00:05:03,930 wondered what on the side show IPV V-6 OSPF and neber notice the neighbor relationship has now moved 42 00:05:03,990 --> 00:05:12,600 to extort and has just moved to full so you can see the neighbor relationship went to fall there. 43 00:05:12,970 --> 00:05:22,100 Brought a one is a PDR and on the side we can see that Rodda T is the designated Rodda. 44 00:05:22,410 --> 00:05:24,990 So we formed a neighbor relationship 45 00:05:27,700 --> 00:05:36,040 with the other rodder without enabling an IP version 6 address on the gigabit 00 interface. 46 00:05:36,040 --> 00:05:43,600 So notice there's no IP version 4 address and there is no IP V-6 address enabled on the interface and 47 00:05:43,600 --> 00:05:46,310 the same is true on the site. 48 00:05:46,780 --> 00:05:57,720 But we do have a neighbor relationship with the other router and if we look at the writing table we 49 00:05:57,720 --> 00:06:04,710 can see at the moment that we have a local network in the running table but no other routes exist. 50 00:06:04,710 --> 00:06:11,710 The show IP V-6 router shows us that a link local address is configured on gigabit 00. 51 00:06:11,910 --> 00:06:20,360 So show IP V-6 interface gigabit 00 shows us that the interfaces up IPV 6 is enabled. 52 00:06:20,480 --> 00:06:24,360 This is the link local address on the interface. 53 00:06:24,360 --> 00:06:31,420 The router has joined various multicast groups including two OSPF groups. 54 00:06:31,470 --> 00:06:43,420 This is all devices on the local segment on the side show run interface gigabit 00 for show IP V-6 interface 55 00:06:43,420 --> 00:06:43,690 Keiga. 56 00:06:43,700 --> 00:06:55,600 But 00 Raba shows us the link a local address on the side so to prove that routing works on Route 1 57 00:06:56,350 --> 00:07:02,780 I'll configure a loopback IP address so IPV 6 address. 58 00:07:02,980 --> 00:07:10,140 And in this case we'll call it 2001 Facebook one. 59 00:07:10,250 --> 00:07:18,050 Colin Colan one slash 1:28 on the site interface link back. 60 00:07:18,050 --> 00:07:25,160 Zero PV 6 address 2001 Facebook 61 00:07:27,760 --> 00:07:30,610 colon colon to 128. 62 00:07:30,640 --> 00:07:33,870 Notice those all 128 networks. 63 00:07:33,940 --> 00:07:37,670 So these two are separate networks. 64 00:07:38,570 --> 00:07:42,310 Show IPV six route. 65 00:07:42,460 --> 00:07:52,800 We have a loopback address in the writing table but we don't see the address because we need to advertise 66 00:07:53,890 --> 00:07:57,940 that network into OSPF. 67 00:07:57,990 --> 00:08:05,460 So now once that network gets advertised we should see it available in the writing table of rodded too. 68 00:08:05,760 --> 00:08:07,550 And there you go. 69 00:08:07,770 --> 00:08:18,960 We have learnt about Facebook one via the link local address of Rotto one once again shows like PV 6 70 00:08:19,650 --> 00:08:22,110 interface gigabit 00. 71 00:08:22,320 --> 00:08:28,170 This is the link local address of router one and that's the address that we are learning the Rampton 72 00:08:28,350 --> 00:08:41,450 from on the side show IPV 6 route we haven't learnt about the loop back on the site and I think I made 73 00:08:41,450 --> 00:08:41,960 a mistake. 74 00:08:41,960 --> 00:08:48,500 So let me double check the configuration I made to the zeros rather than a 2. 75 00:08:48,500 --> 00:08:56,710 So what I'll do is remove that IP address and put it back 76 00:08:59,740 --> 00:09:09,960 to call on column 2 IPV 6 SPF 1 area zero. 77 00:09:10,210 --> 00:09:15,200 Once that network gets advertised we should see it on Broadway one. 78 00:09:15,310 --> 00:09:21,880 And there you go the route is now available on Radu 1. 79 00:09:21,990 --> 00:09:25,780 So we've learnt that the address via OSPF. 80 00:09:25,890 --> 00:09:27,750 Let's try and ping the address. 81 00:09:27,840 --> 00:09:28,780 What do you think. 82 00:09:28,800 --> 00:09:30,370 Will it work. 83 00:09:30,380 --> 00:09:35,150 So Ping IPV 6 address. 84 00:09:35,350 --> 00:09:36,470 Does it work. 85 00:09:36,710 --> 00:09:37,700 Yes it does. 86 00:09:37,940 --> 00:09:48,100 We can ping the loop back of product to the side show IPV 6 ROFFT can we paying 87 00:09:51,910 --> 00:09:53,030 the loop back. 88 00:09:53,320 --> 00:09:59,770 Yes we can notice you don't have to specify IPV 6 The router is intelligent enough to work out that 89 00:09:59,770 --> 00:10:06,700 this is an IPV six ping debug IPV six ICMP. 90 00:10:06,900 --> 00:10:08,140 Let's do that ping again 91 00:10:10,780 --> 00:10:15,620 notice we see that an echo request was received and a reply was sent. 92 00:10:17,040 --> 00:10:26,620 So again the gigabit 0 0 interfaces of both these routers don't have either not provision for address 93 00:10:26,680 --> 00:10:36,640 or an IP version 6 address configured as soon as we enabled IP version 6 on the interface a link a local 94 00:10:36,640 --> 00:10:40,940 address was allocated as shown here. 95 00:10:42,110 --> 00:10:49,370 And OSPF uses a link local addresses for neighbor establishment and romped advertisement and that's 96 00:10:49,370 --> 00:10:51,250 what of demonstrated here. 97 00:10:51,620 --> 00:10:57,010 If you enjoyed the video please like it please subscribe to my YouTube channel. 98 00:10:57,020 --> 00:10:58,520 I wish you all the very best.
