1 00:00:00,390 --> 00:00:04,230 In this lab, you need to configure a grid tunnel. 2 00:00:13,700 --> 00:00:20,930 So in this lab, we need to configure a jewelry tunnel between customer one and Customer two. 3 00:00:21,080 --> 00:00:28,760 We've been told that we need to configure the customer routers to use a DHCP addresses on the internet 4 00:00:28,760 --> 00:00:35,060 interfaces and static IP addresses on the internal interfaces. 5 00:00:36,500 --> 00:00:39,200 So let's start with customer rather one. 6 00:00:44,460 --> 00:00:51,690 I'll go to configuration mode and then go on to gigabit 001. 7 00:00:52,140 --> 00:00:59,610 The interface is currently shut, so I'm going to shut the interface and then I'll configure an IP address 8 00:00:59,610 --> 00:01:01,110 using DHCP. 9 00:01:01,800 --> 00:01:06,330 As you can see, an IP address has been allocated via DHCP. 10 00:01:06,600 --> 00:01:10,500 An IP address of 8.8 to 10.2 has been allocated. 11 00:01:10,950 --> 00:01:14,670 I'll go onto interface gigabyte 000. 12 00:01:14,670 --> 00:01:20,850 No shut of the interface and configure an IP address of ten 111 slash 24. 13 00:01:21,960 --> 00:01:24,630 So show IP interface brief. 14 00:01:24,960 --> 00:01:29,250 We can see that both interfaces are up. 15 00:01:30,140 --> 00:01:34,490 This is the IP address on the Internet facing interface. 16 00:01:34,790 --> 00:01:38,090 This is the IP address on the inside interface. 17 00:01:38,420 --> 00:01:47,300 Internet address was assigned via DHCP internal or customer facing interface. 18 00:01:47,330 --> 00:01:49,520 IP address was configured manually. 19 00:01:51,970 --> 00:01:53,770 That happens because. 20 00:01:54,850 --> 00:02:04,090 The ISP routers are configured as DHCP servers, so show IP DHCP binding. 21 00:02:04,600 --> 00:02:10,720 We can see that this IP address was allocated to this MAC address. 22 00:02:10,990 --> 00:02:22,840 Now we see a DHCP conflict here and that's because IP address 88 10.1 is part of the DHCP pool. 23 00:02:23,140 --> 00:02:33,070 All IP addresses in the subnet are, but the router has this IP address configured on this interface. 24 00:02:33,070 --> 00:02:41,440 So the ISP doesn't allocate its own IP address to the client, but allocates the next IP address in 25 00:02:41,440 --> 00:02:42,250 the pool. 26 00:02:43,100 --> 00:02:47,150 So again, show IP interface brief on the customer router. 27 00:02:47,480 --> 00:02:54,410 This IP address was allocated via DHCP and the router can ping. 28 00:02:56,000 --> 00:02:58,100 The ISP router. 29 00:02:58,730 --> 00:03:01,760 I can do something similar on customer to. 30 00:03:02,990 --> 00:03:06,320 So customer wrote a two show IP interface brief. 31 00:03:07,410 --> 00:03:11,280 Both interfaces are administratively shut down. 32 00:03:11,910 --> 00:03:21,060 So interface gigabit is 001 no shut IP address DHCP interface gigabit is 000. 33 00:03:21,240 --> 00:03:30,900 And while I was typing that an IP address was allocated via DHCP to the router ip address on gigabit 34 00:03:30,960 --> 00:03:36,150 000 is 10.1 to 2.1 slash 24 mask. 35 00:03:37,230 --> 00:03:39,240 I'll no shutter that interface. 36 00:03:40,950 --> 00:03:45,030 So show IP interface brief both IP addresses. 37 00:03:46,050 --> 00:03:53,280 Or configured one dynamically and one statically show IP route shows us the routing table. 38 00:03:53,430 --> 00:04:02,070 Notice a gateway of last resort has been configured and the router also has a default route to its ISP. 39 00:04:02,610 --> 00:04:06,540 So ping eight eight 11.1. 40 00:04:06,900 --> 00:04:11,460 The router can ping its default gateway or ISP router. 41 00:04:15,000 --> 00:04:16,170 Can it ping? 42 00:04:16,350 --> 00:04:19,920 Customer rather one so ping. 43 00:04:22,060 --> 00:04:24,520 8.8.1.2. 44 00:04:24,550 --> 00:04:25,770 Yes, it can. 45 00:04:25,780 --> 00:04:34,180 We could do a trace as an example to that address and you can see that the traffic is going via the 46 00:04:34,180 --> 00:04:34,990 Internet. 47 00:04:35,290 --> 00:04:41,260 In other words, traffic is traversing these links to get to. 48 00:04:42,540 --> 00:04:44,970 Customer rather one as an example. 49 00:04:44,970 --> 00:04:48,000 The second hop is the IP address. 50 00:04:48,420 --> 00:04:51,120 Third hop is the IP address. 51 00:04:51,810 --> 00:04:56,130 So we have IP connectivity between customer one and Customer two. 52 00:04:56,460 --> 00:05:03,930 The next step is to configure a DHCP pool on the customer routers to allocate IP addresses to the PCs 53 00:05:03,930 --> 00:05:05,280 in the network. 54 00:05:06,200 --> 00:05:08,540 So on customer roster one. 55 00:05:09,720 --> 00:05:15,390 Conti ip dhcp pool and you could call this anything. 56 00:05:15,810 --> 00:05:19,320 I'm just going to call it PC in the exam. 57 00:05:19,500 --> 00:05:21,240 Follow the instructions. 58 00:05:21,360 --> 00:05:23,790 But here, there's a little bit of leeway. 59 00:05:23,820 --> 00:05:28,470 You can decide what you want the pool name to be. 60 00:05:29,670 --> 00:05:31,170 Network is going to be this. 61 00:05:31,410 --> 00:05:34,080 Subnet mask is going to be that. 62 00:05:34,470 --> 00:05:37,170 Default router will be ten 111. 63 00:05:38,490 --> 00:05:42,480 So show ip dhcp binding. 64 00:05:42,540 --> 00:05:44,940 We don't have any bindings yet. 65 00:05:45,270 --> 00:05:46,830 Let's look at the PC. 66 00:05:48,480 --> 00:05:54,180 So on its configuration, we need to configure it to use a DHCP. 67 00:05:55,960 --> 00:05:58,390 Go to Desktop Command prompt. 68 00:05:59,670 --> 00:06:08,820 IP config notice it has a got an IP address ten 112 ping ten 111 PC can ping. 69 00:06:09,740 --> 00:06:16,790 Customer Writer one And on the customer roster we can see again that. 70 00:06:17,470 --> 00:06:19,180 There was an address conflict. 71 00:06:19,300 --> 00:06:27,160 So the Rada allocated ten 112 rather than ten 111 to the client. 72 00:06:27,190 --> 00:06:31,900 You could create an exclusion range for your pool. 73 00:06:32,110 --> 00:06:39,280 If you want to make sure that a separate range of addresses are used for the client PCs. 74 00:06:39,930 --> 00:06:43,680 We need to do something similar on customer rather too. 75 00:06:43,710 --> 00:06:51,900 So t ip dhcp pool pc network will be ten 1 to 0. 76 00:06:53,070 --> 00:06:56,610 With the mosque slash 24 mosque. 77 00:06:57,010 --> 00:06:59,490 A default router will be ten 1 to 1. 78 00:07:00,510 --> 00:07:03,240 So show ip dhcp binding. 79 00:07:03,240 --> 00:07:04,710 No bindings yet. 80 00:07:05,700 --> 00:07:07,530 Configure the PC. 81 00:07:09,100 --> 00:07:13,570 To use DHCP go to desktop command prompt. 82 00:07:15,330 --> 00:07:19,920 IP config IP address has been allocated to the PC. 83 00:07:20,640 --> 00:07:27,930 So on the router show IP DHCP binding, the IP address has been allocated to the PC. 84 00:07:28,380 --> 00:07:36,520 So we've successfully created DHCP pools on the customer routers to allocate IP addresses to the PCs. 85 00:07:36,540 --> 00:07:44,700 We now need to configure a red tunnel between customer router one and two so that the PC can ping each 86 00:07:44,700 --> 00:07:45,240 other.
