1 00:00:00,950 --> 00:00:05,330 So our topology is connected, I'll start up all the devices. 2 00:00:06,800 --> 00:00:11,750 What you'll notice is NPM is starting, the GNS3 VM is starting. 3 00:00:13,920 --> 00:00:19,650 So the NPM Windows machine is booted up, the GNS3 VM is booted up 4 00:00:20,800 --> 00:00:25,630 and what I'll do now is open up a console connection to the routers. 5 00:00:27,340 --> 00:00:35,290 So let's start with router 1, what I'm going to do is configure this network as 10.1.1. 6 00:00:35,970 --> 00:00:38,110 0/24. 7 00:00:41,110 --> 00:00:50,710 This network will be 10.1.2.0/24, and this one, 10.1.3.0/24. 8 00:00:51,980 --> 00:00:54,890 I'll also create loop backs on each router 9 00:00:55,950 --> 00:01:02,910 with an IP address that relates to their name. So quadruple 1 for router 1, 10 00:01:04,569 --> 00:01:06,880 quadruple 2 for router 2, 11 00:01:08,470 --> 00:01:11,590 and quadruple 3 for router 3. 12 00:01:13,720 --> 00:01:20,470 Loopbacks are great, these are logical interfaces that don't go down on routers and are very useful for 13 00:01:20,500 --> 00:01:25,780 for management as well as for protocols such as OSPF. So on router 1 14 00:01:28,010 --> 00:01:30,980 create the loopback interface. So quadruple 1 15 00:01:34,550 --> 00:01:45,860 go into the first serial interface, serial 0/0 IP address 10.1.1.1/24 no shut it, go on 16 00:01:45,860 --> 00:01:52,850 to the second interface serial 0/1 IP address 10.1.2.1, 17 00:01:54,890 --> 00:01:56,420 no shut that interface. 18 00:01:59,360 --> 00:02:05,180 I'm going to enable my EIGRP, so router EIGRP 100 network 19 00:02:07,300 --> 00:02:16,480 and I'm going to enable EIGRP in all interfaces and disable automatic summarization. The important 20 00:02:16,480 --> 00:02:21,810 step from a management point of view is to enable SNMP. 21 00:02:22,570 --> 00:02:30,010 So I'm going to say SNMP server community and I'm going to specify a community of NPM 22 00:02:31,250 --> 00:02:33,140 and I'm going to set it to Read-Only 23 00:02:34,430 --> 00:02:42,350 and then I'm going to save the configuration. Do something similar on router 2, so on router 2 24 00:02:42,350 --> 00:02:44,510 loopback 0, IP address 25 00:02:48,780 --> 00:02:49,710 quadruple 2, 26 00:02:52,990 --> 00:03:00,010 interface serial 0/0, IP address 10.1.1.2 27 00:03:01,740 --> 00:03:09,420 no shut it, serial 0/1 IP address 10.1.3.2. 28 00:03:11,860 --> 00:03:23,320 No shut that interface, router EIGRP 100 network and enable EIGRP in all interfaces and disable 29 00:03:23,320 --> 00:03:24,850 automatic summarization. 30 00:03:26,790 --> 00:03:28,170 Last router, router 3 31 00:03:31,930 --> 00:03:33,160 create a loopback interface 32 00:03:37,040 --> 00:03:37,940 quadruple 3 33 00:03:41,210 --> 00:03:52,130 /32 mask, go into the serial interface IP address 10.1.2.3, no shut 34 00:03:52,130 --> 00:03:52,360 it 35 00:03:53,390 --> 00:03:58,070 second serial interface IP address 10.1.3.3 36 00:03:59,620 --> 00:04:13,120 no shut that interface, enable EIGRP on all interfaces, disable automatic summarization, 37 00:04:15,960 --> 00:04:18,089 neighbor relationships are being established 38 00:04:21,390 --> 00:04:30,300 and importantly mustn't forget to type SNMP server community, the community name NPM read-only. 39 00:04:31,370 --> 00:04:34,600 Need to do that on both router 2 and router 40 00:04:34,750 --> 00:04:47,290 3 SNMP server community, NPM Read-Only, and I'll save the configurations. 41 00:04:49,530 --> 00:04:58,410 So that's the initial configuration on our routers, show IP EIGRP neighbors shows me that router 42 00:04:58,410 --> 00:05:00,780 2 has 2 neighbor relationships, 43 00:05:01,950 --> 00:05:06,540 router 1 has 2 neighbor relationships, 44 00:05:09,950 --> 00:05:19,310 and so does router 3, router 3 can ping the loopback of router 1 and the loopback of router 2, router 45 00:05:19,310 --> 00:05:26,090 1 can ping the loopback of router 2 and the loopback of router 3. 46 00:05:27,020 --> 00:05:34,670 So I have configured this network with IP addresses on the serial interfaces and the routers can ping each 47 00:05:34,670 --> 00:05:34,990 other. 48 00:05:35,450 --> 00:05:44,210 The next step is to enable the management network and get NPM to manage the devices. 49 00:05:47,280 --> 00:05:52,530 So to configure the management interface, I'm going to go in the FastEthernet interface of router 50 00:05:52,530 --> 00:06:07,140 1 and give it an IP address of 10.1.100.1/24 mask and save the config, router 2 Fast 51 00:06:07,140 --> 00:06:13,460 Ethernet interface given address of 10.1.100.2/24 mask 52 00:06:15,300 --> 00:06:16,620 save this config 53 00:06:19,890 --> 00:06:30,270 and do something similar on router 3 10.1.100.3/24 mask 54 00:06:34,190 --> 00:06:35,990 save the configuration. 55 00:06:37,820 --> 00:06:45,140 So our devices have booted up, we've connected NPM to the topology, let's test connectivity from 56 00:06:45,140 --> 00:06:45,350 NPM. 57 00:06:47,000 --> 00:07:00,080 So here's my NPM Windows Machine IP config shows me the IP address of 10.1.100.100, ping 10.101 58 00:07:00,830 --> 00:07:01,430 that's router 59 00:07:01,430 --> 00:07:06,590 1 ping succeed, router 2 pings succeed, 60 00:07:07,400 --> 00:07:10,000 router 3 pings succeed. 61 00:07:10,820 --> 00:07:18,230 So NPM has IP connectivity to the three routers using the management network. 62 00:07:18,890 --> 00:07:23,210 Now let's get NPM to discover the devices. 63 00:07:23,600 --> 00:07:25,310 In other words, the three routers.
