1 00:00:09,670 --> 00:00:16,090 In this lab, you need to configure a grid tunnel geometry or generic routing. 2 00:00:16,090 --> 00:00:25,180 Encapsulation is a tunneling technology that allows you to create a point to point tunnels over an IP 3 00:00:25,180 --> 00:00:27,370 network such as the Internet. 4 00:00:28,270 --> 00:00:36,790 Multiple protocols can be encapsulated over Jori and you can run routing protocols across a geo tunnel. 5 00:00:37,360 --> 00:00:42,760 The disadvantage of geo tunnels is that they don't support encryption. 6 00:00:43,570 --> 00:00:53,170 If you want the added benefit of jury encrypted tunnels, you typically encapsulate a grid tunnel over 7 00:00:53,170 --> 00:00:54,850 an IP tunnel. 8 00:00:55,270 --> 00:00:58,060 IP SEQ provides the encryption. 9 00:00:58,430 --> 00:01:07,180 GRI allows you to encapsulate multiple protocols and run routing protocols across the grid tunnel. 10 00:01:07,420 --> 00:01:15,940 Cisco Devices now support many types of tunnels such as DLM, VPN and others, but Jory is one of the 11 00:01:15,940 --> 00:01:20,230 oldest and most simple tunneling technologies. 12 00:01:20,680 --> 00:01:29,380 In this lab, you need to configure a GRC tunnel from customer one to Customer two via the Internet 13 00:01:29,380 --> 00:01:31,540 routers in the topology. 14 00:01:31,870 --> 00:01:38,830 There are three Internet routers, ISP router one, ISP router two and ISP router three. 15 00:01:39,220 --> 00:01:43,810 Each of these routers is running BGP in a separate autonomous system. 16 00:01:44,110 --> 00:01:52,630 The BGP configuration has already been completed and as you can see here, ISP router two has two BGP 17 00:01:52,630 --> 00:01:53,620 relationships. 18 00:01:54,220 --> 00:01:57,610 So show IP BGP summary. 19 00:01:58,540 --> 00:02:02,770 Shows us that the router has two BGP relationships. 20 00:02:03,570 --> 00:02:10,380 To one relationship to ISP one and another to ISP three. 21 00:02:11,039 --> 00:02:14,970 Here are the list of tasks that you need to complete in this lab. 22 00:02:15,880 --> 00:02:19,780 You need to configure customer orders, see one and see two. 23 00:02:20,080 --> 00:02:30,190 In other words, this rata and this router to use DHCP IP addresses on gigabit 001 and static IP addresses 24 00:02:30,190 --> 00:02:36,040 as shown in the diagram on gigabit 000. 25 00:02:36,670 --> 00:02:46,690 The ISP routers, ISP one and ISP three have been configured with DHCP and these routers will allocate 26 00:02:46,690 --> 00:02:50,470 IP addresses to the customer routers. 27 00:02:51,230 --> 00:02:58,190 So you need to configure these interfaces with DHCP and these interfaces with static IP addresses. 28 00:02:58,610 --> 00:03:05,270 You then need to configure a DHCP pool on the customer routers to allocate IP addresses to the PCs. 29 00:03:06,220 --> 00:03:13,900 So on customer writer one and customer wrote a to create a DHCP pool and allocate IP addresses to the 30 00:03:13,900 --> 00:03:14,920 PCS. 31 00:03:14,920 --> 00:03:21,010 In these subnets, ensure that the PCs learn about their default gateways. 32 00:03:21,190 --> 00:03:25,960 In other words, PC ones default gateway will be customer router one. 33 00:03:26,230 --> 00:03:29,500 PC two's default gateway will be customer out of two. 34 00:03:29,860 --> 00:03:37,990 You then need to configure a tunnel between C one and C two so that PC one and PC two can ping each 35 00:03:37,990 --> 00:03:41,470 other using RFC 1918 addresses. 36 00:03:41,950 --> 00:03:45,460 Network ten is an RFC 1918 address. 37 00:03:45,790 --> 00:03:54,760 So these PCs will need to be able to ping each other via the Jio tunnel, use a tunnel interface of 38 00:03:54,760 --> 00:04:01,030 tunnel zero on both Customer one and Customer two and use IP addresses of ten. 39 00:04:01,030 --> 00:04:04,090 One, two, three, one and ten, one, two, three, two. 40 00:04:04,090 --> 00:04:11,410 On the tunnel interfaces to enable routing between customer side one and customer side two, you need 41 00:04:11,410 --> 00:04:21,130 to enable IGP and Autonomous System 100 and advertise this network via the Jio tunnel to customer router 42 00:04:21,130 --> 00:04:28,960 one so that the router and the PC can ping both this IP address as well as PC two. 43 00:04:29,470 --> 00:04:39,910 This network also needs to be advertised by IGP through the tunnel so that Customer two and PC two can 44 00:04:39,910 --> 00:04:43,630 ping both the IP address and PC one. 45 00:04:43,870 --> 00:04:50,500 So as a verification, make sure that the customer routers can ping each other on their gigabyte 000 46 00:04:50,500 --> 00:04:54,910 interfaces and that PC one and PC to can ping each other. 47 00:04:56,200 --> 00:05:03,430 These routers in the Internet such as I-spy two, will not learn about the Ten Network. 48 00:05:03,730 --> 00:05:10,150 They should only know about the 8.8.6. X Networks. 49 00:05:12,320 --> 00:05:18,590 Ten 000/8 is an RFC 1918 or private address. 50 00:05:18,770 --> 00:05:27,620 So we are going to tunnel private addresses through the Internet via a tunnel so that these devices 51 00:05:27,620 --> 00:05:28,760 can ping each other. 52 00:05:28,910 --> 00:05:34,220 Even though the ISP routers don't know about those networks. 53 00:05:34,640 --> 00:05:37,610 So can you complete this lab? 54 00:05:38,000 --> 00:05:43,790 Download the attached packet, trace a file and see if you can complete the lab yourself. 55 00:05:44,060 --> 00:05:48,230 Otherwise, watch the next video where I complete the lab.
