1 00:00:00,860 --> 00:00:04,220 The next step is to configure the DHCP server. 2 00:00:05,430 --> 00:00:15,510 So I'm going to call this rather DHCP server to enable IPV six unicast routing on gigabit zero one. 3 00:00:16,570 --> 00:00:26,090 Configure an IP version six address of 2001 colon 1 to 3 four colon colon to flash 64 and no shutter 4 00:00:26,110 --> 00:00:27,160 the interface. 5 00:00:27,850 --> 00:00:36,100 I'm also going to configure a static route to the face and network via 2001. 6 00:00:36,100 --> 00:00:37,050 One, two, three, four. 7 00:00:37,060 --> 00:00:37,450 Colon. 8 00:00:37,450 --> 00:00:38,590 Colon one. 9 00:00:38,620 --> 00:00:40,780 In other words, the relay agent. 10 00:00:41,170 --> 00:00:45,860 So can the DHCP server ping the relay agent? 11 00:00:45,880 --> 00:00:46,960 Yes, it can. 12 00:00:47,230 --> 00:00:52,450 Can it ping the face interface on the relay agent? 13 00:00:52,480 --> 00:00:53,590 Yes, it can. 14 00:00:54,010 --> 00:00:58,720 So essentially this DHCP server capping the relay agent. 15 00:00:59,720 --> 00:01:06,460 Now that we've completed the basic IP version six configuration, we need to configure the DHCP server. 16 00:01:06,470 --> 00:01:10,040 So IPV six DHCP. 17 00:01:11,240 --> 00:01:19,610 In this case, we're going to configure a pool and I'm going to call it my pool address prefix is going 18 00:01:19,610 --> 00:01:24,230 to be 2001 face colon, colon slash 64. 19 00:01:24,590 --> 00:01:27,740 The face network is on the left hand side. 20 00:01:27,740 --> 00:01:30,740 So that's the address prefix that we're going to allocate. 21 00:01:30,860 --> 00:01:40,460 We'll also allocate a DNS server, which is going to be the local router, and we'll configure a domain 22 00:01:40,460 --> 00:01:41,090 name. 23 00:01:44,270 --> 00:01:47,050 Of CNA Dexcom. 24 00:01:48,050 --> 00:01:53,330 So that's what should be sent through to the client through DHCP. 25 00:01:54,300 --> 00:02:02,640 Now on the gigabit is there are one interface we need to use this command IPV six DHCP server. 26 00:02:03,370 --> 00:02:06,180 And point it to the pool that we've created. 27 00:02:06,190 --> 00:02:07,450 So my pool. 28 00:02:08,800 --> 00:02:11,800 So this is the configuration of the DHCP server. 29 00:02:13,360 --> 00:02:21,640 We've essentially configured a DHCP pool as follows and on the gigabit zero one interface, the interface 30 00:02:21,640 --> 00:02:24,040 that's going to receive the DHCP requests. 31 00:02:24,580 --> 00:02:30,190 We have configured an IP address as well as a server pool. 32 00:02:31,150 --> 00:02:35,650 So let's do a debug ip of six dhcp. 33 00:02:36,350 --> 00:02:38,750 So that's the server configuration done. 34 00:02:39,730 --> 00:02:39,970 Okay. 35 00:02:39,970 --> 00:02:42,150 So now let's configure the client. 36 00:02:42,160 --> 00:02:50,470 So I'll call this client, I'll enable IPV six unicast routing and then on gigabit to zero zero we'll 37 00:02:50,470 --> 00:02:52,690 use the command IPV six address. 38 00:02:53,200 --> 00:03:00,220 In this case we're going to use DHCP and then I'll enable IPV six on that interface. 39 00:03:00,970 --> 00:03:05,920 Before I know shut to the interface I'm going to do a debug IPV six DHCP. 40 00:03:07,190 --> 00:03:08,090 At the moment. 41 00:03:08,090 --> 00:03:17,240 We told that gigabit zero zero is not ready, so show IPV six interface gigabit is zero zero. 42 00:03:17,450 --> 00:03:23,270 At the moment the interface is down, but notice we do have a link local address. 43 00:03:24,320 --> 00:03:24,560 So. 44 00:03:24,560 --> 00:03:25,580 Interface gigabit. 45 00:03:25,670 --> 00:03:26,780 Zero zero. 46 00:03:26,810 --> 00:03:27,440 No. 47 00:03:27,440 --> 00:03:28,250 Shut. 48 00:03:29,420 --> 00:03:31,100 Let's see what happens now. 49 00:03:33,560 --> 00:03:40,880 What you'll notice in the output is that a solicitation was sent to all routers on the segment. 50 00:03:41,930 --> 00:03:46,640 A DNS server was configured as well as a domain name. 51 00:03:51,620 --> 00:03:52,970 On the relay agent. 52 00:03:52,970 --> 00:04:00,860 It received the solicitation from from a host ending with this link local address which is. 53 00:04:01,960 --> 00:04:03,520 Which if I scroll up. 54 00:04:06,520 --> 00:04:08,110 Is the client. 55 00:04:10,000 --> 00:04:12,940 The relay was forwarded to the DHCP server. 56 00:04:13,060 --> 00:04:16,480 A reply was received from the DHCP server. 57 00:04:17,269 --> 00:04:26,360 And the reply was sent to the client on the dhcp server relay was received from the relay agent. 58 00:04:28,130 --> 00:04:28,580 Pull. 59 00:04:28,580 --> 00:04:30,890 My pull is going to be used. 60 00:04:31,400 --> 00:04:34,970 A binding is created for the client. 61 00:04:36,490 --> 00:04:40,930 A new address is going to be allocated to the client of this. 62 00:04:41,590 --> 00:04:44,350 So the address is going to be allocated. 63 00:04:45,580 --> 00:04:48,070 The source IP address is going to be this. 64 00:04:49,080 --> 00:04:55,860 It's sending a relay reply and it's updating the binding source address is going to be that. 65 00:04:57,760 --> 00:05:07,000 The relay is once again sent to the relay agent, so show IPV six interface gigabit is zero zero. 66 00:05:07,280 --> 00:05:08,440 Notice the link. 67 00:05:08,440 --> 00:05:13,930 Local addresses this, but the router has been allocated this address. 68 00:05:14,630 --> 00:05:17,300 That's for this subnet. 69 00:05:18,420 --> 00:05:19,830 What I'll do is. 70 00:05:20,930 --> 00:05:22,610 Shut to the interface down. 71 00:05:23,000 --> 00:05:31,280 We can see some messages on the DHCP server and then I'll shut the interface again. 72 00:05:32,540 --> 00:05:39,600 So interface has come up and the router is getting an IP address through DHCP.
