1 00:00:16,170 --> 00:00:16,470 Okay. 2 00:00:16,470 --> 00:00:23,580 So in this lab, we've been told to configure the network so that calls can be made between the IP phones 3 00:00:23,580 --> 00:00:29,730 and we need to ensure that we have connectivity between devices in this network. 4 00:00:30,510 --> 00:00:34,860 I'm going to start with the configuration of the Cisco router. 5 00:00:41,650 --> 00:00:45,250 But the writer has just booted up show IP. 6 00:00:45,340 --> 00:00:51,760 Interface brief shows us that no IP addresses are configured on the router. 7 00:00:52,690 --> 00:00:58,030 So first thing I'll do is go on to F zeros, slash zero. 8 00:00:58,330 --> 00:01:02,170 I could not shatter this interface, but I'll leave that till later. 9 00:01:02,560 --> 00:01:05,440 So I'll go on to the sub interface. 10 00:01:05,830 --> 00:01:13,780 If a zero slash is 0.1, I'll configure an IP address of ten .1.1.25 for. 11 00:01:14,680 --> 00:01:19,330 Per these instructions on a VLAN one. 12 00:01:22,830 --> 00:01:24,820 Going to use a slash 24 mosque. 13 00:01:25,150 --> 00:01:26,540 And notice the problem. 14 00:01:26,560 --> 00:01:29,250 I need to type encapsulation dot one q. 15 00:01:29,500 --> 00:01:38,170 Specify a vlan in this case vlan one and then I need to make it the native VLAN. 16 00:01:38,200 --> 00:01:40,660 In other words, the untagged vlan. 17 00:01:40,660 --> 00:01:44,680 And now I can put an IP address on the interface. 18 00:01:45,770 --> 00:01:48,440 So do show run shows us. 19 00:01:50,140 --> 00:01:53,380 The configuration of the sub interface. 20 00:01:55,090 --> 00:02:02,080 I'm going to give the router a name just because I like doing that so that I know which device I'm working 21 00:02:02,080 --> 00:02:02,500 on. 22 00:02:03,770 --> 00:02:08,479 I'll create the next sub interface, which is sub interface 100. 23 00:02:09,770 --> 00:02:11,810 That's for VLAN 100. 24 00:02:13,070 --> 00:02:16,100 The sub interface numbers don't have to match the subnet. 25 00:02:16,490 --> 00:02:21,920 I just like to do that to make it easier to troubleshoot. 26 00:02:22,850 --> 00:02:24,530 VLAN is going to be 100. 27 00:02:24,770 --> 00:02:26,900 It's not the native VLAN. 28 00:02:27,200 --> 00:02:34,490 IP address is ten one 102.4 subnet mask. 29 00:02:36,000 --> 00:02:37,440 So do Shia run? 30 00:02:38,650 --> 00:02:41,200 We've got two sub interfaces configured. 31 00:02:44,640 --> 00:02:47,070 I'm going to configure Sub Interface 101. 32 00:02:47,700 --> 00:02:53,700 IP address is ten 1101254 slash 24 mask. 33 00:02:54,060 --> 00:03:00,960 And again, I need to configure the encapsulation as a VLAN 101. 34 00:03:01,710 --> 00:03:04,740 And then I can configure the IP address. 35 00:03:05,220 --> 00:03:06,780 So verification. 36 00:03:07,900 --> 00:03:12,340 We've got three sub interfaces configured on the router. 37 00:03:12,730 --> 00:03:14,140 That looks good. 38 00:03:14,710 --> 00:03:18,790 I now need to configure dhcp pools under the router. 39 00:03:19,930 --> 00:03:23,110 So ip dhcp pool. 40 00:03:25,720 --> 00:03:26,860 Give it a name. 41 00:03:27,220 --> 00:03:28,900 I'm just going to call this PC's. 42 00:03:28,930 --> 00:03:32,560 You could have called that data if you preferred. 43 00:03:33,640 --> 00:03:35,230 Name doesn't really matter. 44 00:03:35,680 --> 00:03:38,440 Subnet mask is going to be a slash 24 mask. 45 00:03:38,920 --> 00:03:47,170 Default router is going to be ten 125 for a DNS server is going to be the router. 46 00:03:48,160 --> 00:03:56,080 So verification days are configuration of the DHCP pool for the pcs. 47 00:03:56,680 --> 00:04:00,820 I need to do something similar for the phones. 48 00:04:01,480 --> 00:04:04,870 You could have called this voice or phones. 49 00:04:04,870 --> 00:04:05,860 It doesn't matter. 50 00:04:06,310 --> 00:04:11,590 Again, use whichever term you want in the exam. 51 00:04:11,590 --> 00:04:14,770 Follow what they tell you to do. 52 00:04:15,710 --> 00:04:25,610 Network is that default gateway is going to be the router option 150 is the TFTP server, so we need 53 00:04:25,610 --> 00:04:35,270 to specify that with an IP address being of the router, the phones will get their configuration from 54 00:04:35,270 --> 00:04:36,170 the router. 55 00:04:36,650 --> 00:04:44,990 Now again, you may want to create an exclusion range so you could do something like IP, DHCP excluded 56 00:04:44,990 --> 00:04:52,730 address and specify the range of addresses that are going to be excluded for, let's say, the data 57 00:04:52,730 --> 00:04:53,540 VLAN. 58 00:04:55,220 --> 00:04:57,260 And the voice vlan. 59 00:04:58,170 --> 00:05:00,780 I've just chosen some arbitrary values here. 60 00:05:01,750 --> 00:05:04,660 In the exam, follow what they tell you to do. 61 00:05:04,870 --> 00:05:08,170 It's really up to you in the real world. 62 00:05:08,170 --> 00:05:15,460 Decide how many addresses you need to allocate and how many need to be excluded for servers. 63 00:05:16,180 --> 00:05:19,540 That's quite a big range for a small network like this. 64 00:05:19,840 --> 00:05:26,080 So I've configured the router with inter VLAN routing as well as DHCP pools. 65 00:05:26,440 --> 00:05:31,840 I'm now going to configure the switch and then I'll configure the telephony service.
