1 00:00:12,530 --> 00:00:15,260 So I can ping rather too. 2 00:00:16,580 --> 00:00:20,420 What about the IP address on the other side of right of two? 3 00:00:20,930 --> 00:00:22,790 I can ping that IP address. 4 00:00:22,910 --> 00:00:24,620 What about router one? 5 00:00:24,770 --> 00:00:27,440 I can successfully ping router one now. 6 00:00:28,190 --> 00:00:29,720 So back on rata one. 7 00:00:30,230 --> 00:00:34,460 I should be able to ping router three, which I can. 8 00:00:34,970 --> 00:00:40,070 So we've successfully configured routing between router one and router three. 9 00:00:41,460 --> 00:00:44,880 On Raw two three show IPV six interface brief. 10 00:00:45,480 --> 00:00:50,640 I now need to configure an IP address on gigabit 0/0. 11 00:00:51,360 --> 00:00:53,850 So interface gigabit 0/0. 12 00:00:53,850 --> 00:00:59,220 No shut IP V6 Address 2001. 13 00:00:59,220 --> 00:01:01,320 Colon three, colon colon one. 14 00:01:01,320 --> 00:01:02,970 Slash 64. 15 00:01:04,050 --> 00:01:06,960 So show IPV six interface brief. 16 00:01:07,740 --> 00:01:14,400 This IP address is now configured under this interface, but the interface is up down. 17 00:01:14,670 --> 00:01:30,720 So on router four, I need to configure both a hostname as well as an IP address on gigabit 0/0. 18 00:01:33,510 --> 00:01:34,710 So there you go. 19 00:01:35,040 --> 00:01:39,540 Interface has come up on router three show IPv6 route. 20 00:01:40,170 --> 00:01:44,040 We can see this network in the routing table. 21 00:01:44,670 --> 00:01:50,220 We should be able to ping router four which we can. 22 00:01:51,780 --> 00:01:53,190 Router four. 23 00:01:55,980 --> 00:01:59,340 Has this IP address configured on gigabit. 24 00:01:59,400 --> 00:02:00,930 0/0. 25 00:02:01,290 --> 00:02:04,620 But it doesn't have any static routes configured. 26 00:02:05,280 --> 00:02:15,120 So I need to configure IP version six study grants for the networks that are not directly connected 27 00:02:15,690 --> 00:02:17,010 to router four. 28 00:02:17,310 --> 00:02:21,090 So that network as well as this network. 29 00:02:23,060 --> 00:02:31,220 So in Rata four we should be able to ping this IP address, which we can, but we won't be able to ping 30 00:02:31,220 --> 00:02:40,610 rata two because router two doesn't know how to get back to router four en route to show IPV six root 31 00:02:40,970 --> 00:02:46,550 router two doesn't have a static route to this network. 32 00:02:47,060 --> 00:03:01,580 So on router two IPV six root 2001 colon three colon colon slash 64 2001 colon two colon colon two. 33 00:03:01,970 --> 00:03:10,460 So now can write a full ping router two yes it can, can write a full ping right of one. 34 00:03:13,830 --> 00:03:19,920 The answer is it can't because rather one it needs to be configured 35 00:03:22,380 --> 00:03:26,340 with a static route to get back to router four. 36 00:03:26,370 --> 00:03:29,970 So IPV six, route 2001, colon three. 37 00:03:29,970 --> 00:03:34,350 Colon colon slash 64, 2001 colon one. 38 00:03:34,350 --> 00:03:35,910 Colon, colon two. 39 00:03:36,450 --> 00:03:37,980 So show IPV six. 40 00:03:37,980 --> 00:03:45,360 Route router one has to study roots one to this network and one to this network. 41 00:03:45,720 --> 00:03:50,880 En route of four we can now ping router one with static roots. 42 00:03:51,120 --> 00:03:55,620 And this is true for both IP version four as well as IP version six. 43 00:03:55,740 --> 00:04:03,780 You need to configure static roots on every device for every network that's not directly connected to 44 00:04:03,780 --> 00:04:04,590 the router. 45 00:04:05,040 --> 00:04:09,900 So rather one this network and this network are not directly connected. 46 00:04:09,930 --> 00:04:12,060 So we need to study grafts. 47 00:04:13,430 --> 00:04:18,260 And rather for this network and this network are not directly connected. 48 00:04:18,950 --> 00:04:28,160 So we need to configure to study grants on router to only this network is not directly connected. 49 00:04:28,760 --> 00:04:35,420 So on router two, we only need to configure a single study grant. 50 00:04:35,750 --> 00:04:39,170 And that's true for rider three as well. 51 00:04:39,290 --> 00:04:40,970 Show IPV six route. 52 00:04:41,630 --> 00:04:49,160 We only had to configure this static route for this network because that's the network that's not directly 53 00:04:49,160 --> 00:04:51,260 connected to Router three. 54 00:04:51,530 --> 00:04:58,370 To make it work, you need a static route to every network that's not directly connected to you. 55 00:04:59,750 --> 00:05:02,510 Notice what happens if I remove the static route? 56 00:05:02,750 --> 00:05:05,570 So I'll remove the static, right? 57 00:05:08,970 --> 00:05:19,110 And back on writer one wool writer one be able to ping rather four And the answer is no because rather 58 00:05:19,110 --> 00:05:26,250 one knows that to get to write a four it needs to send the traffic to write a two because of the study 59 00:05:26,250 --> 00:05:26,910 grant. 60 00:05:28,160 --> 00:05:37,070 Wrote two knows that to get to that network it needs to send the traffic to router three rather three. 61 00:05:37,100 --> 00:05:39,050 Has this network directly connected? 62 00:05:39,290 --> 00:05:43,040 So the traffic gets to router for router four. 63 00:05:43,310 --> 00:05:55,310 Returns the traffic to router three, but now rather three doesn't know how to send the traffic back 64 00:05:55,310 --> 00:05:56,600 to router one. 65 00:05:56,690 --> 00:05:58,340 So the packets are dropped. 66 00:05:58,520 --> 00:06:04,730 So the traffic gets to router four with ping, we get return traffic hits router three. 67 00:06:04,820 --> 00:06:12,560 But the return traffic can't get back to right of one because we've removed the study grant if I added 68 00:06:12,560 --> 00:06:13,490 that back. 69 00:06:14,670 --> 00:06:16,020 Back on writer one. 70 00:06:17,180 --> 00:06:18,920 Pings now succeed. 71 00:06:19,550 --> 00:06:25,940 So in this network, we configured IP version six addresses as well as static routes. 72 00:06:26,240 --> 00:06:28,010 How did you do with the lab? 73 00:06:28,040 --> 00:06:29,840 Were you able to complete it? 74 00:06:30,200 --> 00:06:31,430 Did you get to the lab? 75 00:06:31,430 --> 00:06:32,210 Working. 76 00:06:32,500 --> 00:06:34,130 Hope you enjoyed this video. 77 00:06:34,160 --> 00:06:35,960 Hope you enjoyed the lab. 78 00:06:35,990 --> 00:06:37,910 Keep on practicing.
