1 00:00:06,370 --> 00:00:10,320 This is a practical IP version 4 subnetting lab. 2 00:00:10,420 --> 00:00:17,050 Now, this is a practical lab helping you test and verify your knowledge of IP version 4 subnetting. 3 00:00:17,050 --> 00:00:23,860 We're not simply gonna talk about the theory of IP version 4 subnetting you need to subnet, but in 4 00:00:23,860 --> 00:00:28,080 addition configure the network and get it working. 5 00:00:28,360 --> 00:00:35,020 You need to configure IP addresses on routers, on switches, and on DHCP servers and then you need to configure 6 00:00:35,050 --> 00:00:41,300 the DHCP servers to allocate IP addresses to the clients in the correct subnet. 7 00:00:41,320 --> 00:00:48,880 So once again this is a practical demonstration and lab of IP version 4 subnetting, in this packet 8 00:00:48,880 --> 00:00:49,770 tracer lab. 9 00:00:49,780 --> 00:00:57,370 We have multiple sites, site 1 and site 2 connected via serial links to an Internet router. 10 00:00:57,490 --> 00:01:05,650 You need to configure the network as follows, you've been allocated subnet 1 9 2 1 6 8 1. 0 slash 24 and 11 00:01:05,650 --> 00:01:12,430 you need to subnet this network into 4 subnets as follows subnet 1 needs to be allocated to site 1 12 00:01:12,430 --> 00:01:22,360 subnet 2 to the serial link between router 1 and the Internet router, subnet 3 to site 2 and subnet 13 00:01:22,360 --> 00:01:27,470 4 to the link between router 2 and the Internet router. 14 00:01:27,640 --> 00:01:34,930 Now, we are not going to initially optimize the subnetting you're only gonna create 4 subnets and 15 00:01:34,930 --> 00:01:42,460 then split them across these four networks in a subsequent video we'll optimize the serial links to 16 00:01:42,460 --> 00:01:48,350 use a slash 30 mask and then make more subnets available for additional sites. 17 00:01:48,430 --> 00:01:52,690 But in this initial topology, you simply need to create 4 subnets. 18 00:01:52,900 --> 00:01:56,410 You should configure the router as per the instructions in the diagram. 19 00:01:56,410 --> 00:02:02,660 In other words this interface on router 1 should use the last IP address in the relevant subnet. 20 00:02:02,680 --> 00:02:08,259 This interface should use the first IP address in the subnet on the serial link. 21 00:02:08,259 --> 00:02:14,770 The Internet router is gonna use the last IP address in both subnets on the serial links and router 22 00:02:14,770 --> 00:02:22,300 2 will once again use the last IP address in the subnet on the Ethernet interface and to the first 23 00:02:22,330 --> 00:02:25,210 IP address on the serial interface. 24 00:02:25,210 --> 00:02:31,570 You need to configure the switches with the second to last IP address and the subnet and the DHCP servers 25 00:02:31,570 --> 00:02:40,990 with the third last IP address in the subnet, as an example at Site 1 the switch such 1 should be 26 00:02:40,990 --> 00:02:47,650 configured with the second last IP address and the subnet and the DHCP server with the third last IP 27 00:02:47,650 --> 00:02:48,590 address. 28 00:02:48,730 --> 00:02:55,630 The same should be done for switch 2, in site 2 and the third last IP address should be configured on 29 00:02:55,630 --> 00:02:59,280 the DHCP server at site 2. 30 00:02:59,320 --> 00:03:06,550 You also need to configure the DHCP servers to allocate IP addresses to the clients in the relevant subnets. 31 00:03:06,550 --> 00:03:11,850 So as an example DHCP server 1 should allocate IP addresses to PC 0, 32 00:03:12,010 --> 00:03:20,620 PC 1 and PC 2 in the subnet allocated to this network, DHCP server 2 should allocate IP addresses 33 00:03:20,950 --> 00:03:24,680 in the correct subnet to PC 3 4 and 5. 34 00:03:24,700 --> 00:03:31,270 Once you've done your configuration verify that PCs can access cisco.com and facebook.com 35 00:03:31,330 --> 00:03:33,100 using their browsers. 36 00:03:33,100 --> 00:03:38,380 The server 8.8.8.8 is configured as a DNS server. 37 00:03:39,130 --> 00:03:46,330 So think of this as the Google DNS server that is configured with A records for cisco.com and facebook 38 00:03:46,330 --> 00:03:47,430 .com 39 00:03:47,440 --> 00:03:54,040 So once you've got your network configured with the correct IP addresses your DHCP servers are allocating 40 00:03:54,280 --> 00:04:01,070 IP addresses to the clients, the clients should be able to access cisco.com and facebook.com, 41 00:04:01,120 --> 00:04:05,320 again this is the DNS server in the network. 42 00:04:05,530 --> 00:04:08,050 Okay, so can you complete this lab? 43 00:04:08,090 --> 00:04:14,550 Can you work out the relevant subnets, the relevant IP addresses, and configure the routers switches and 44 00:04:14,550 --> 00:04:18,410 DHCP servers to get this network working. 45 00:04:18,410 --> 00:04:23,230 Download the packet tracer file and see if you can complete the lab yourself. 46 00:04:23,270 --> 00:04:27,050 Otherwise watch the next video where I complete the lab.
